NGEN – Algorithmic MIDI Workstation – User Manual

About NGEN

NGEN is a unique 16-track MIDI sequencer designed in São Paulo / Brazil that lets you combine multiple algorithmic / generative generators and MIDI FXs to sequence multiple hardware or software MIDI instruments.

It offers a completely new way of creating and performing music by abstracting the composition process. Instead of writing sequences from scratch, NGEN lets you quickly generate a new sequence for your drums, basslines, melodies, and chord progressions with a push of a button.

NGEN includes classic Spektro Audio generators (ACDGEN and Polyform), completely new algorithmic generators (Drumgen, Samba, Arper, MARP, Pop, Turing, Shuffler), and practical generators (Input Sequencer, MIDI Player, Thru).Each generator features an algorithm to combine different composition techniques with randomness so each generated sequence is unique.After generating a sequence, you can tweak it in real time using the parameters available for each of the generators. Take things even further by applying MIDI FXs such as Chord or Glitch to your sequences.All tracks in NGEN follow the same key and scale so it’s easier to get multiple sequences that work well with each other.Quickly save and restore your creations using patterns and projects stored in the microSD card.

NGEN's design is primarily focused on live performance so it features a 1.3" OLED screen, a minimalistic and easy to read interface, mechanical switches (Gateron Green), shortcuts for accessing different features, per track Program Change selector and auto-variation, extensive MIDI CC implementation, and a Performance mode for controlling up to 4 parameters at the same time.

NGEN also includes a variety of tools to let you explore this world of algorithmic sequencing such as assignable CV outputs, a built-in MIDI monitor, different clock generators, and much more.

How to Use ↵

Getting Started

Getting Started with NGEN

To get started with NGEN, simply connect it to a computer or another USB-host device via USB, or to a MIDI-capable device via the MIDI Out jack.

The MIDI Clock generator is active by default, so NGEN should be ready to receive MIDI Clock from a DAW or external gear to NGEN.

By default, all 16 tracks are set up to output MIDI to channels 1 through 16 sequentially however only the first track is active when the device is turned on (more tracks can be enabled via the Track Settings).

Attention - ADVANCED MODE

Many advanced settings (such as track routing and Clock Rate) are hidden by default to provide a more streamlined experience to new users.
To access these settings, enable the "Advanced Mode" in the Settings / General page.
To keep your current settings, save your settings after enabling Advanced Mode.

Step-By-Step Guide

This guide provides a step-by-step process to initiate NGEN:

1 - Connecting NGEN to your setup

In this first section, you'll learn how to connect NGEN to your setup and use it to sequence 1 instrument using the ACDGEN generator.

  1. Establish a connection between NGEN and a computer or a MIDI-enabled hardware instrument. If you do not intend to use NGEN with a computer, you can power the unit externally.

  2. Configure your MIDI instrument or destination to receive MIDI notes on Channel #1:

    1. If you're utilizing NGEN with a computer, launch your preferred DAW, create an instrument/MIDI track, load a virtual instrument, and set it to receive MIDI from NGEN's Channel 1.

    2. If you're employing a hardware synthesizer, ensure it's configured to receive MIDI on Channel 1.

  3. Initiate one of NGEN's Clock Generators:

    1. If you wish to synchronize NGEN to a MIDI Clock from your DAW or instrument, ensure they're configured to output MIDI Clock to NGEN via USB or the MIDI IN jack.

    2. If you prefer to use NGEN's internal clock, navigate to the Main Menu, proceed to the Clock sub-menu, hold the TRACK / CLK button and move the MENU ENCODER to select the Free Clock, then click the encoder to activate it.

  4. NGEN should now begin transmitting MIDI Notes to your instrument.

  5. By default, NGEN will load ACDGEN as the generator for track #1 so you should hear a sequence being played on your instrument.

2 - Generating and Modifying Sequences Using ACDGEN

Now that NGEN is connected and transmitting MIDI notes to your instrument, let's see how to generate and modify sequences using the ACDGEN generator.

Attention

The first 3 sub-menus available in the Main Menu (Generator, MIDI FX and Track) are related to the selected track while the other sub-menus contain global settings.

  1. Return to the Main Menu using the RETURN button and navigate to the Generator sub-menu. This sub-menu contains all the parameters available for the active generator in the selected track (in this case, ACDGEN).

Note

While in the Generator sub-menu, the NGEN displays the name of the active generator in the top-left corner and the selected track number in the right corner.

  1. Use the MENU ENCODER to scroll through the parameter list.
  2. To modify the value of the selected parameter, click the MENU ENCODER to select the value, scroll to adjust it, and click the encoder to return to the parameter selection.
  3. The main 4 parameters of the active generator can also be accessed through the ** PARAM 1-4 potentiometers** (except while in certain sub-menus). Additional 4 parameters can be accessed by holding the FUNCTION button and turning the PARAM 1-4 potentiometers. More information about the behavior of the potentiometers can be found in the Hardware Controls section.
  4. To generate a new sequence, click the GENERATE button.

For more information about Generators, check the Generators section.

3 - Activating a MIDI FX

Let's try adding a MIDI FX to the active track to modify the sequence generated by ACDGEN in real time.

  1. From the Main Menu, navigate to the Track sub-menu to access the track's parameters. This sub-menu lets you activate/deactivate the track, select the active generator and MIDI FX, and adjust settings related to MIDI routing, clock division, and more.
  2. Navigate to the MIDI FX parameter and click the MENU ENCODER to select the desired MIDI FX.
  3. Scroll through the list of available MIDI FXs using the MENU ENCODER, select the Glitch MIDI FX, and click the encoder to confirm.
  4. Return to the Main Menu and navigate to the MIDI FX sub-menu to access the parameters of the active MIDI FX.

Attention

While in the MIDI FX sub-menu, PARAM 1-4 potentiometers control the parameters of the active MIDI FX as indicated by the knob icon on the top of the screen.

For more information about MIDI FXs, check the MIDI FX section.

4 - Adding More Tracks

Because NGEN is a multi-track sequencer, you can switch between tracks to edit their parameters and sequences. Let's add a new track and configure it to output MIDI notes to Channel 2.

  1. To open the track selector, click the TRACK|CLK button from the Main Menu or any sub-menu.
  2. Use the MENU ENCODER to scroll through the list of available tracks, select track #2, and click the encoder to confirm.
  3. Use the shortcut FUNCTION + TRACK to jump to the Track sub-menu.
  4. Only track 1 is active by default, so activate track 2 by scrolling to the Active parameter and clicking the MENU ENCODER to toggle it on.
  5. Navigate to the Generator parameter and select a different generator for track 2.
  6. By default, the 16 tracks available in NGEN are set to output MIDI notes to channels 1 through 16 sequentially. To access the parameters related to MIDI routing, clock division, and more, enable the Advanced Mode in the Settings / General page.

For more information about tracks, check the Track section.

5 - Using Patterns

NGEN allows you to create and store 8 patterns per project. In this section, you'll learn how to save and load patterns.

  1. Click the PATTERN button to open the Pattern selector.
  2. Use the MENU ENCODER to scroll through the list of available pattern slots.
  3. To quickly save your active sequence to a pattern slot, press FUNCTION + PATTERN.
  4. To load a pattern, scroll to the desired pattern slot and click the MENU ENCODER.
  5. To access the pattern slot settings, click FUNCTION + PATTERN while in the pattern selector. This sub-menu lets you save, delete, copy and paste patterns.

For more information about patterns, check the Pattern section.

6 - Saving Your Project

In this final section, you'll learn how to save your project for future use.

Attention

Projects can be stored in the internal memory of NGEN or on an external microSD card. To save your project to the internal memory, ensure that the microSD card is not inserted.

  1. Return to the Main Menu and navigate to the Project sub-menu.
  2. Scroll to the Save parameter and click the MENU ENCODER to save your project.
  3. Edit the project name using the MENU ENCODER and confirm.

For more information about projects, check the Project section.

Flow Diagram

The NGEN sequencing engine works by having a clock generator trigger the tracks' generators and MIDI FXs.

The notes generated by each track's generator and MIDI FX are routed to the track's main and auxiliary output. The MIDI output of all tracks is sent to external instruments via the USB and MIDI (A-style 1/8" jack) ports.

Hardware Setup

Connecting NGEN to other your setup

NGEN can be connected to computers, drum machines and synthesizers via USB, MIDI and CV. These connections can also be used simultaniously.

Connecting via USB

The simplest way to use NGEN is to connect it to your computer via USB.

The USB connection powers the unit and it's capable of sending and receiving MIDI since it works as a Class Compliant MIDI device.

Connecting via MIDI

NGEN can also be connected to other gear via the MIDI IN and MIDI OUT 3.5mm TRS jacks (Type-A).

Please note that NGEN still needs to be powered via USB (check the Powering NGEN section below).

Connecting via CV

NGEN also features 2 pairs of CV + Gate outputs that can be used to sequence other hardware instruments (such as modular synthesizers).

More information about the available CV modes is available in the Settings section.

The four outputs are available as two pairs of additional outputs available via the Aux Out parameter in the Track sub-menu.

To route the output of a track to one of the CV outputs:

1 - Enable Advanced Mode (Settings / General).

2 - Select one of the available CV modes (Settings / CV Out).

3 - Select the track you'd like to route to one of the CV output.

4 - Open the Track sub-menu, navigate to the Aux Out parameter and set it to CV 1 or CV 2.

WARNING

The CV and Gate jacks are OUTPUTS only. Do not send any CV signals into them or you may run the risk of damaging your unit.

Please note that NGEN still needs to be powered via USB (check the Powering NGEN section below).

Powering NGEN externally

If you'd like to set up NGEN without a computer, you can power it using a USB power bank / battery or a standard USB wall charger.
NGEN's power consumption is minimal so even a 0.5A charger should work.

Note

Because of NGEN's low power consumption, certain USB power banks can dismiss it as an actively charging device and may turn off after a certain period. If this happens, try using a different power bank or a USB wall charger.

I2C Connection

NGEN features an 1/8 TRS I2C connection on it's left side wired with SDA on the TIP and SCL on RING.

We plan on adding I2C-related features in future NGEN firmware updates.

WARNING

Do not connect any CV outputs or other signals via 1/8 to the I2C connection otherwise you may damage your unit.

Hardware Controls

Hardware Controls on NGEN

The NGEN includes a main clickable encoder (MENU ENCODER), a return button (RETURN), 4 parameter knobs (PARAM 1 through PARAM 4), and 4 buttons (TRACK/CLK, PATTERN, FUNCTION, and GENERATE) that can be used to access and control different features.

Encoder

The MENU ENCODER can be used for navigating menus, activating patterns, selecting the active track/clock, selecting different parameters, changing their value, and selecting files.

Turn the MENU ENCODER to select a different sub-menu, file or parameter.
Press/Click the MENU ENCODER to select a sub-menu or file or switch between parameter selection and value adjustment.

The MENU ENCODER can also be combined with other buttons to perform different operations.

Please refer to the shortcuts table for more information.

Knobs

The 4 knobs (PARAM 1, PARAM 2, PARAM 3, and PARAM 4) in NGEN serve different purposes depending on which menu is active.

The default behavior of the 4 parameters is to control the main parameters of the selected Generator of the active Track.

Additional parameters can be controlled by turning the 4 knobs while holding down FUNCTION.

{}

NGEN Knob Icon

While in the MIDI FX, SCALE and CLOCK menus, the 4 knobs are mapped to parameters related to those features (note the knob icon on the top section of the display). Exiting those menus will revert the knob mapping to the Generator parameters.

Pick-up Behaviour

If the position of a knob does not match the value of the parameter that it's trying to control, the knob gets disabled and enters a pick-up state.

While in this state, a pick-up screen will be displayed to indicate the position of the knob relative to the parameter's value.

To re-enable the knob, turn the knob so its position matches the current value of the parameter.

Buttons

The four hardware buttons included in NGEN perform specific functions when pressed individually. Shortcuts and secondary functions can be accessed via Shortcuts (see table below).

  • TRACK / CLK : Enables track/clock selection (by holding the button down and turning the MENU ENCODER).

  • PATTERN : Selects the active pattern.

  • FUNCTION : Modifies the behavior of the other buttons to enable access to additional functions (see Shortcuts).

  • GENERATE : Call the main function of the active Generator, MIDI FX or Clock.

  • RETURN : Returns to the previous menu.

Shortcuts

A list of shortcuts available is available on the Menu Navigation page.

Special Behavior

Certain NGEN features (such as the scale editor, name editor, and file selector) can have more control over NGEN's hardware controls and, as such, can use the available hardware controls in different ways.

The standard behavior for NGEN's controls should be restored once you complete the operation or exit the feature (e.g. by pressing the RETURN button).

Menu Navigation

The NGEN menu system is designed to be easy to navigate using the MENU ENCODER and the RETURN button.

The unit boots into the Main Menu which lets you access all the different features available in NGEN. We've limited the maximum depth of the menu system to two levels (MAIN MENU > FEATURE SUB-MENU).

Use the MENU ENCODER to scroll through the list of features and click the MENU ENCODER to navigate to a sub-menu. To return to the previous menu, press the Return button.

Different sub-menus can contain different menu items such as parameters, toggle switches, and actions which can be selected by scrolling the menu MENU ENCODER.


  • Parameters (indicated by the parameter name on top and value at the bottom) can be controlled by clicking the MENU ENCODER to access the parameter's value and scrolling the MENU ENCODER to change it's value.

Note

Most parameter values are adjusted in real-time as you turn the encode but some (such as the Generator and MIDI FX selection in the Track sub-menu) require you to click the encoder to confirm the new value.


Clicking the encoder on parameters switches between parameter selector and value


  • Switches can be toggled by clicking the MENU ENCODER.


  • Actions (indicated by the action name displayed on the center of the screen) can be called by clicking the MENU ENCODER.

NGEN includes a variety of different features, settings and parameters that lets you use it in a variety of different ways but, to make it easier for you to get started, certain advanced parameters and settings are hidden by default.

To enable the advanced mode, go to Settings, enable Advanced and save your settings.

To better display the appropriate information, NGEN automatically switches between different modes (Menu Navigation, Idle, and Parameter Visualization).

Menu Navigation is the default mode of the display.

When moving one of the PARAM knobs, NGEN will display the name, current value, and range of the parameter currently mapped to that knob.

While in Generator or Clock sub-menus, the display will switch to the selected Idle mode (Animation or Parameter List) after 5 seconds of no hardware interaction unless Idle Mode is set to OFF.

NGEN includes unique animations for Generators and Clock Generators, designed to provide visual feedback of their current state/functionality.

While displaying an animation, parameters modified via the 4 PARAM knobs are displayed on the top section of the display to prevent obstructing the animation.

This idle mode displays a list of the parameters currently mapped to the 4 PARAM knobs and it's designed to help users get used to different mappings.

In order to prevent display burn-in, NGEN's display will go into screensaver mode after a certain period (determined by the Screensaver Period setting) of no hadware interaction (unless it's displaying an animation). The screensaver does not affect other functions so NGEN will continue to work normally while in screensaver mode.

To exit the screensaver mode, move any of the knobs or click on any of the buttons.

File Management

About File Management

NGEN can use external files to store and load data for Projects, MIDI files, DrumGen templates, and NSL scripts. These files can be either be stored in the microSD card or in NGEN's internal memory.

During it's boot process, NGEN checks if a microSD card is inserted. If no microSD card is inserted, NGEN will use its internal memory instead.

NGEN currently doens't offer a way of transferring files between its internal memory and the microSD card (coming soon).

Using NGEN with a microSD card

We recommend using microSD cards with a capacity of 32GB or less, formatted as FAT32.

Before inserting a microSD card into NGEN, we recommend that you copy the Factory Content to the microSD card in order to have the necessary folders for MIDI files, DrumGen templates, and NSL scripts.

Factory Content

The Factory Content for NGEN (including MIDI files, DrumGen templates, and NSL scripts) is available on the NGEN Resources repository on Github.

If you'd like to download or update the Factory Content, follow these steps:

1 - Download a copy of the Factory Content available on the NGEN repository on Github.

2 - Navigate into the Factory Content folder and copy the contents to the root of your microSD card.

Attention

It's currently not possible to copy new files into NGEN's internal memory. If you'd like to use new files available in the Factory Content, you'll need to use a microSD card.

MIDI Mapping

About MIDI Mapping

Most of the settings, parameters, and actions available in NGEN can be controlled, modulated, and automated via MIDI CC. This lets you automate parameters during a live set or even use an external MIDI controller to access certain parameters directly.

MIDI CC messages are routed to Tracks according to their IN CH (MIDI Input Channel) settings. The values received are processed depending on the behaviour of the parameter / setting / action (check MIDI chart below).
The different behaviours are:

  • Scaled: values 0-127 are scaled to the parameter's minimum and maximum range.
  • Action: values greater than zero trigger the action.
  • Absolute: the value is used directly according to the range described (values outside of the described range are ignored).

Because NGEN uses MIDI Channel 16 for global settings, tracks set to IN CH 16 will only receive MIDI notes.

Warning

In order to receive MIDI CC messages, you must first enable "MIDI CC RX" in Settings / MIDI sub-menu.

NSL - NGEN SCRIPTING LANGUAGE

The NSL Engine Generator is a powerful tool that lets you create your own custom algorithms using a simple scripting language.

At it's core, the NSL Engine features a 32-step sequence (with individual pitch, velocity, length (in beats) and density per step) and standard parameters such Shift, Length and Density to control playback.

Instead of using a pre-defined algorithm to fill the 32-step sequence, the NSL Engine lets you load a script to generate it using your own custom algorithm.

Each NSL script consists of a series of hex values that are parsed into commands and values. Hex values above 160 (0xA0) trigger new commands and values below 160 are assigned as values / parameters for these commands. The engine also includes 32 registers (Memory Buffer) that can be used to store values and use them later in the script and 4 generic parameters (Param 1-4) with ranges from 0-100.

Warning

The NSL Engine is still in beta and it's not fully documented and implemented yet. This section of the manual will be updated as we continue to develop the NSL Engine. Faulty scripts can cause the NSL Engine to crash and require a reboot.

ngen_nsl Rust Library

ngen_nsl is a custom Rust library available via cargo / crates.io that make it easier to create and parse NSL scripts for the NSL Engine.

To add it to your Rust project, run the command cargo add ngen_nsl in your project's directory.

Documentation for ngen_nsl is available at https://docs.rs/ngen_nsl.

NSL Programming Reference

Parameter Types

NSL commands require set of different parameters to execute correctly and each parameter's value is used according to the list below:

VALUE

The VALUE parameter type returns a constant values from 0x00 to 0x7F (0-127) and values stored in the NSL Engine's memory buffer from 0x80 to 0x9F (128-159).

DESTINATION / SOURCE

The DESTINATION / SOURCE parameters consists of 2 x VALUE parameters that are used in pair to retrieve values from different parts and features of the NSL Engine.

SOURCE parameters are used to retrieve data while DESTINATION parameters are used to set data.

The first VALUE in the pair (aka VALUE 1) is used to indicate the type / location of the value that follows it (VALUE 2) according to the table below:

PART / FEATURE VALUE 1 (Address) VALUE 2 (Value / Index) VALUE 2 RANGE SOURCE DESTINATION DESTINATION RANGE
Constant Value 0x00 Value 0-127 ✔︎ ✕ N/A
Random Value 0x01 Random Range 0-127 ✔︎ ✕ N/A
Step Pitch 0x02 Step Number (Zero-Indexed) 0-31 ✔︎ ✔︎ 0-127 (MIDI PITCH)
Step Velocity 0x03 Step Number (Zero-Indexed) 0-31 ✔︎ ✔︎ 0-127 (MIDI VELOCITY)
Step Length 0x04 Step Number (Zero-Indexed) 0-31 ✔︎ ✔︎ 0-32 (BEATS)
Step Density 0x05 Step Number (Zero-Indexed) 0-31 ✔︎ ✔︎ 0-49
Memory Buffer 0x06 Step Number (Zero-Indexed) 0-31 ✔︎ ✔︎ 0-255
Params 1-4 0x07 Parameter Number (Zero-Indexed) 0-3 ✔︎ ✔︎ 0-100
Scale 0x08 Note position in scale 0-127 ✔︎ ✕ N/A
Scale (Quantized) 0x09 Note position in scale 0-127 ✔︎ ✕ N/A

Some features such as Constant and Random use the second VALUE in the pair (VALUE 2) as the actual value while the other types use it as an index to indicate the location of the value in the NSL Engine's memory.

Examples:

  • 0x00 0x05 : Returns a constant value (ORIGIN = 0x00) of 5 (VALUE = 0x05).
  • 0x02 0x10 : Returns the step pitch (ORIGIN = 0x02) at index 16 (VALUE = 0x10).
  • 0x07 0x20 : Returns a random value (ORIGIN = 0x07) between 0 and 32 (VALUE = 0x20).

INT16

The INT16 parameter type uses a pair (x and y) of 8-bit values (0-255) to create a 16-bit value (0-65535) by shifting the first value 8 bits to the left and adding the second value to it ((x << 8) + y).

Generator

About Generators

NGEN Generator Sub-menu

The generators in NGEN are used to generate MIDI notes/sequences to play external MIDI instruments.

Each generator uses a specific algorithm to create a unique MIDI sequence based on certain ideas, musical styles, and production techniques. These sequences can then be modified and interacted with via the different parameters available in each generator.

The output of each generator is routed to the Track's both MIDI out and Aux Out (which can be used to send MIDI notes from one track to another).

Each track can load any of the available generators.

Info

The animations for each generator are displayed via the Idle Mode feature while in the Generator sub-menu. To see the animations, set Idle Mode is set to Animation in the Settings, navigate to the Generator sub-menu and leave the machine idle until the display switch to the Idle Mode.

Generator Parameters

While in the GENERATOR sub-menu or the MAIN MENU, the main parameters of the selected generator are mapped to the NGEN 4 knobs (PARAM 1, PARAM 2, PARAM 3, and PARAM 4):

  • 4 Parameters are mapped to the knobs directly.
  • 4 Additional parameters are accessible by holding down FUNCTION while moving the knobs.

Some parameters such as Length, Shift and Density are available in many of the available generators. These common parameters are always mapped to the same knobs to improve usability and consistency.

A complete list of parameters available for the selected Generator can be accessed via the GENERATOR sub-menu available in the MAIN MENU.

The MIDI velocity of generated chords is determined by the Velocity and Balance parameters. Velocity determines the base velocity of the chords and Balance determines the correlation between MIDI velocity and note lenghts.
At 50, Balance uses the same velocity for short and long notes. At 0, short notes will have a higher velocity and long notes will have a lower velocity. At 100, short notes will have a lower velocity and long notes will have a higher velocity.

Modes:

• STABS: Generates a sequence of stabs (short chords) that can be used for house, techno, and other dance music genres. In this mode, Density disables certain chords in the sequence based on their density value.

Patterns

About Patterns

The pattern system in NGEN is designed to let users create and perform different sections of a song/project. Patterns can store and recall settings for all tracks (including their Generators and MIDI FX). Global and clock settings are only stored in Projects.

Each Project contains 8 pattern slots that can be saved, copied, pasted, and deleted from the Pattern Selector menu (accessible via the PATTERN button).

The Pattern Selector displays the active pattern on the left (ACTIVE), the selected pattern on the center (NEXT) and the Generator and MIDI FX selected for the first 3 active tracks.

Loading / Queuing Patterns

NGEN offer 3 methods for loading / queuing patterns:

1 - Press the PATTERN button to open the Pattern Selector, select the pattern using the MENU ENCODER and click on the encoder to load.

2 - Turn the MENU ENCODER while holding down the PATTERN button to select a pattern, release the button to load the selected pattern.

3 - Use the shortcuts PATTERN + GENERATE to load the next pattern in the sequence or PATTERN + FUNCTION + GENERATE to load the previous pattern in the sequence.

Patterns are queued and loaded at the beginning of the next bar if NGEN is playing or immediately if NGEN is stopped.

Saving Patterns

The changes you make in NGEN are not automatically saved to the current pattern to avoid accidental overwriting of patterns.

To save the current pattern to one of the available slots, follow these steps:

1 - Open the Pattern Selector by pressing the PATTERN button.

2 - Select which pattern slot you'd like to save the current pattern to by turning the MENU ENCODER.

3 - Open the Pattern Edit menu by holding down the FUNCTION button and pressing the PATTERN button.

4 - Select the Save option to save the current pattern to the selected slot.

It's also possible to use the shortcut PATTERN + MENU ENCODER to save the current pattern to the selected slot while in the Pattern Selector.

Pattern Generation

NGEN includes a new Pattern Generation feature that lets users generate an entire pattern at once by holding down TRACK | CLK and pressing the GENERATE button. This shortcut will generate new sequences for all active tracks.

If the Randomize State setting is enabled, NGEN will also assign random states to all tracks when generating a new pattern.
For more information about track states, check out the Track States section in the Track documentation.

It's also possible to generate variations of the current pattern by holding down TRACK | CLK + FUNCTION and pressing the GENERATE button.




Pattern Menu

The pattern edit menu can be accessed by holding down the FUNCTION button and pressing the PATTERN button (accessible from the Main Menu or from the Pattern Selector).

The menu includes options for saving, copying, pasting, and deleting the selected pattern.




Generate All / Variate All

The last 2 options in the Pattern menu are Generate All and Variate All. These options let you explore NGEN's algorithmic pattern generation capabilities by generating or variating all patterns at once starting from the selected pattern.
These features can be used to create all 8 patterns in a project at once or to fill subsequent empty patterns.

Generate All generates 8 unique patterns and automatically saves them to the current project.

Variate All generates 8 variations of the current pattern and automatically saves them to the current project.

Warning

Generate All and Variate All won't affect / overwrite already saved patterns. If you'd like to overwrite a pattern, make sure to delete it first.




Pattern Reloading

NGEN includes a new feature that lets users quickly reload the active pattern from it's last saved state by holding down PATTERN and pressing the RETURN button.

This feature is useful for quickly reloading an entire pattern after making changes to it during a live performance.




Workflow Suggestion

The pattern system can be used to create, store and load different variations based on the initial pattern.

After creating your first pattern, return to the Main Menu and save it as pattern one.
You can then create different variations by tweaking the different parameters and generating new sequences. To save each variation, load an empty pattern and save the current variation to it.

Performance Mode

About Performance Mode

NGEN includes a dedicated performance mode available under the PERFORM sub-menu.

Performance Mode includes 8 macro parameters that let you map up to 4 parameters of any Generator or MIDI FX, in any track, per macro and set specific ranges for each mapping.

Macro mappings are stored in Project files and are recalled automatically when you load a Project.

Macro mapping

Macro mapping process

To map a parameter to a macro:

1 - Navigate to the PERFORM sub-menu

2 - Select a macro and click on the MENU ENCODER to adjust the macro mappings.

3 - Select the parameter slot number(Param #).

3 - Select the > Map To Param to activate mapping mode (indicated by the M→ icon on the display's top section).

4 - Navigate to a parameter and press the MENU ENCODER to select the displayed parameter.

5 - Adjust the minimum and maximum values via the Min and Max settings.

Track Muting

While in the PERFORM sub-menu, you can use the 4 buttons (TRACK | CLK, PATTERN, FUNCTION, and GENERATE) to mute/unmute the first 4 tracks.

Muting works by disabling the track instead of affecting the Generator's parameters.



Projects

About Projects

Similarly to standard DAWs, NGEN can save and load entire sessions as project files. These files are stored in a microSD or directly to NGEN's internal memory (HW version 1.1 and above).

A project file contains data for Tracks (including data for the active Generators, MIDI FX and I/O routings), Clock Generators, Scale, Perform Mode, and Patterns.

After saving or loading a project, that project becomes the active project for all Patterns.

To save a project, navigate to the Projects sub-menu, select the Save or Save As option. Save As option will prompt you to name the project file.

To load a project, navigate to the Projects sub-menu, select the Load option, and select what file you'd like to load.

To create a new project file, navigate to the Projects sub-menu, select the New option. This will clear all data from the current project and create a new one.

Projects can not be renamed through NGEN's interface. To rename a project, connect the microSD card to your computer (via a microSD to USB adapter) and rename the files inside the Projects folder (we suggest limiting the filename to 10 characters).

Loading and Saving Projects During Playback

It is possible to load and save projects while NGEN is playing without any interruptions.

Projects are cached and loaded at the beginning of the next bar. This allows you to switch between projects as if you were switching between patterns.
This feature is particularly useful for live performances and jam sessions where projects can used to different songs or sections of a song.

NGEN uses a separate core to handle the loading and saving of projects, ensuring that the audio engine is not interrupted during the process.

Attention

If you plan on switching between projects during a performance, make sure you have the same Clock Generators enabled in the projects you're switching between.

Scale

About Scale

Because NGEN is designed with live performance in mind, most of the Generators process notes in terms of musical intervals rather than specific notes. Therefore these Generators use the selected Key and Scale in the SCALE sub-menu to translate those intervals to the appropriate notes.

This approach lets the user change the Key and Scale of all Tracks simultaneously via the SCALE sub-menu (available in the MAIN MENU).

A global Octave control is also available under the Scale sub-menu.

List of Available Scales

  • Minor

  • Major

  • Harmonic Minor (mHARM)

  • Melodic Minor (mMELO)

  • Major Pentatonic (MPENT)

  • Minor Pentatonic (mPENT)

  • Blues

  • Dorian (DORIA)

  • Lydian (LYDIA)

  • Locrian (LOCRI)

  • Arabic (ARAB)

  • Augmented (AUGM)

  • Wholetone (WHOLE)

  • Phrygian (PHRYG)

  • Chromatic (CHROM)

Scale Editor

The Scale Editor allows you edit the currently selected scale by enabling or disabling notes.

Use the MENU ENCODE to select a note and press the MENU ENCODE to toggle it on or off.

To return to the Scale menu, press the RETURN button.

Warning

The Scale Editor is a beta feature and subject to change. Changes made in the Scale Editor are only temporary. Selecting a different scale will reset the changes made in the Scale Editor.

Tools

About Tools

The Tools sub-menu contains different features that can be used to monitor, control, and configure NGEN's settings.

List of Available Tools

MIDI MONITOR (MONITOR)

The built-in MIDI Monitor lets you track incoming and outgoing MIDI messages. It can be used to make sure that NGEN is receiving MIDI clock, notes, and control changes from other devices and that it's also sending MIDI messages appropriately.

The four columns in the MIDI Monitor represent message type, number (note or CC number), value, and channel.

To switch between IN and OUT, press the GENERATE button.

TEMPLATE

The Template tool lets you load different track setup templates (Generator / MIDI FX / Clock Rate / Routings) to your current pattern.

Available templates:

Tracks

About Tracks

The NGEN features 16 tracks that work similarly to MIDI tracks in standard DAWs. Each track contains different settings for active Generator, MIDI FX, Program Change, routing, and more.

These settings can be accessed via the TRACK sub-menu (available in the MAIN MENU) or the FUNCTION + TRACK shortcut.

Track Selection

Track Selector

Because NGEN's controls are mapped to the active track by default, it's important to be able to quickly switch between tracks.

To select a different track:

  1. Press the TRACK / CLK button to open the track selection screen.

  2. Use the MENU ENCODER to scroll through the available tracks.

  3. Press the MENU ENCODER to select a track.

For quicker selection, turn the MENU ENCODER while holding down the TRACK / CLK button.

Tracks Internal Routing

When triggered by a Clock Generator, a track will advance the active Generator. The MIDI output of the Generator is then sent to the input of the active MIDI FX.

The MIDI output of the MIDI FX is then routed to the track's main and auxiliary outputs. The main output is always routed to the USB / MIDI Out on the selected MIDI channel (OUT CH). The auxiliary output, on the other hand, can be used to send a copy of the MIDI messages generated by the track (post-MIDI FX) to different destinations such as another track or one of the CV outputs.

Tracks can also receive MIDI from external sources (via USB or MIDI IN) and other tracks (routed via the AUX OUT). Some Generators (such as Polyform) can process incoming MIDI notes.

Auto Variate (AUTO VAR) Enable / disable the Auto Variate mode

Track Edit

The Track Edit sub-menu can be accessed via the shortcut FUNCTION + TRACK | CLK from the Track sub-menu and it contains options for copying, pasting and clearing the track.

The Copy and Paste options let you quickly copy the settings of one or more tracks and paste them into another track. Keep in mind that internal data for the selected Generator and MIDI FXs (including sequences and parameter settings) are not copied.

The Clear option resets the track's settings to their default values.

Track States

To create more dynamic patterns, NGEN can control the prominence of each track in new patterns via the Track State feature.
When generating new patterns (TRACK + GENERATE), NGEN can assign a random state to each track (according to the Randomize State setting).
When a new state is assigned to a track, it randomizes key parameters of the active Generator within ranges defined by the state.

Available states:

State Description
Standard Medium intensity and sequence length
Low Low intensity and medium sequence length
Mute Mutes the track (via Density or Probability parameters)
Fill High intensity and shorter sequence lengths
Sparse Lowest intensity and longer sequence lenghts

Tips & Techniques

About this section

NGEN can be used in a variety of different ways and this section is designed to help you get started with some of the most common techniques.

Tips & Techniques

Tips for Live Performance

Here's a list of some tips that can help you get the most out of NGEN when performing live:

Organizing your songs

One way to organize song ideas is by utilizing the 8 available patterns within each project to store distinct sections of a song. For instance, you can use pattern 1 for the intro, pattern 2 for the verse, pattern 3 for the chorus, and so on.

Additionally, projects can be used to store different songs. For example, you can use project 1 for song 1, project 2 for song 2, etc.

NGEN is capable of loading projects and patterns while playing so you can use this to switch between songs and sections of a song while performing. Switching between different projects and patterns is always done in sync with the clock and it's designed to be as smooth as possible.

Using shortcuts

NGEN includes several shortcuts that can help you during your performance. A list of all shortcuts can be found in the Menu Navigation section of the manual.

Using the Performance Mode

The Performance Mode is a powerful tool for live performances. You can use it to control multiple parameters of different tracks at the same time. You could use the Performance Mode, for example, to control the density, octave, and mode of multiple tracks at once.

Using an external MIDI controller for NGEN

While NGEN may only feature 4 hardware knobs, it's possible to control most of its parameters and features via MIDI CC. This means that you can use an external MIDI controller to control NGEN's parameters and expand the number of real-time hardware controls available.

If you have a MIDI controller with a 3.5mm MIDI jack, you can connect it to NGEN's MIDI IN jack. Controllers with MIDI DIN jacks can be connected to NGEN via a MIDI cable and a DIN to 3.5mm (Type-A) adapter.

Because NGEN works as a USB client, USB MIDI Controller can only be used with a separate USB Host device or a computer (that forwards the MIDI messages from the controller to NGEN).

A full list of NGEN's MIDI CC mappings can be found in the MIDI Mapping section of the manual.

Automating parameter changes via MIDI CC

The MIDI CC mappings can also be used to automate parameter changes via a DAW or other MIDI-capable device. This can be used to perform programmatic/automatic changes to NGEN's parameters (such as Key and Scale) according to the needs of your performance.

Combining Multiple Tracks for 1 Instrument

The standard workflow for NGEN is to utilize one track per instrument, but it's also possible to employ multiple tracks for the same instrument. This approach allows you to combine different Generators and MIDI FX to create more intricate and complex sequences.

To achieve this, simply set the Output Channel of all tracks to the same value. From there, you can use the second track to add or modify the notes generated by the first track.

Here's a list of some great combinations that we've found during our testing:

  • DRUMGEN + Samba: DrumGen can be used to sequence the main elements of your drum section (kick, snare, hihats) while Samba can sequence other percussive elements.

  • POP + Arper: In this combination, POP can be used to generate the main chord progression while Arper can be used to add a repeating arpeggio pattern on top of it.

  • 2X ACDGEN: Two ACDGEN tracks can be combined to create more intricate sequences. Try setting the 2 ACDGEN tracks to different algorithms and/or octaves for more interesting results.

Extra tips for combining multiple tracks:

  • Use different clock rates for each track (1/16 and 1/8 for example).
  • Explore contrasting settings for the generators. Use the available parameters to set different densities, octaves, and voicing modes (monophonic vs. polyphonic).
  • Use MIDI FXs like the Shaper to control the velocity of the notes generated by each track.

Using DRUMGEN and SAMBA to generate melodic sequences

DrumGen and Samba are primarily designed to sequence percussive instruments however it's also possible to use them to generate interesting polyphonic sequences. Use the Note 1 through 4 parameters to set them to any other 4-note chord.

The Note Length parameter in Samba allows you to switch between different length modes, which can have a significant impact when used with melodic instruments.

Chaining MIDI FXs

While NGEN only allows one MIDI FX per track, it's possible to chain multiple MIDI FXs by using the Aux Output of a track and the Thru Generator.

To chain MIDI FXs, follow these steps:

  • Select the track you'd like to chain MIDI FXs to.
  • Set the MIDI FX of that track to the first MIDI FX you'd like to use.
  • Set the Aux Output to another available track.
  • Select the track that you set the Aux Output to and set its Generator to Thru.
  • Set the MIDI FX of the Thru track to the next MIDI FX you'd like to use.

Repeat these steps for each MIDI FX you'd like to chain.

Attention

Keep in mind that each track will continue to output MIDI to the selected Output Channel so, to avoid sending duplicate MIDI messages, set the Output Channel of each track to a different value.

AUTO VARIATE (AUTO VARI8)

The Auto Variate feature in NGEN is designed to automatically generate sequence variations for enabled tracks after a certain number of bars. This feature works on a per-track basis and can be enabled or disabled for each track via the Auto Vari8 toggle available on the Track sub-menu.

When enabled, the Auto Variate feature will generate a new sequence variation for the track after a certain number of bars. The probability of the variation being generated can be set via the PROB parameter, and the amount of variation can be set via the VARIATION parameter.

Auto Variate settings are global and affect all tracks that have the feature enabled.

Parameter Description
Probability The probability of the variation being generated
Length (Bars) The number of bars before a new variation is generated
Variation Amount (Amount) The amount of variation to be generated
