Arbhar is a new generation Eurorack granular processor. The sampled audio is chopped into short tones, blended, varying pitches and layered endlessly for a wide range of audio operations, from frozen smooth tones to glitched live instrumental sounds. I will.With a small condenser microphone built into the panel, audio analysis for automatic sampling, and internal modulation, Arbhar delivers unparalleled granular synthesis.

With the introduction of firmware version 2 (2023), we implement both technical and conceptual improvements.Complete rewrite of entire codebaseThis has improved the overall Arbhar user experience while keeping the overall feel the same.Increased efficiency and expanded capabilities will allow Arbhar to explore even more acoustic and musical spaces.

Arbhar uses a granular process to chop up captured audio or sound files loaded from USB and play them back, altering them in various ways.A single fragment of audioGrainIt is called. Arbhar can play 88 grains at the same time, creating thick sound layers.

Arbhar provides various parameters to control grain, and almost all of them can be controlled by voltage.Grain playback position, spread, level, etc. across modulesLED displayWill be reflected in the display.

Playback-related parameters include the recording playback position, the length of the note being played, the playback direction, the volume envelope, and the pitch.Some parameters, such as pitch and playback direction, can be randomized using only Arbhar's built-in functions.


The explanation of each part is displayed by mouse over

Input Section

At Arbhar,Main input jack, Onset Analysis input jack, built-in condenser microphoneYou can record sound from three input sources: .

Routing is microphone → onset input → main inputInternal connectionSo, for example, the sound from the microphone is input when not patched to the main and Onset inputs. At the input stageAnalog limiterIs installed to prevent digital clipping due to excessive volume.

Onset analysis Onset Analysis monitors and analyzes the spectrum of the input sound, and when it changes significantly.Automatically trigger recordingTo do.It is also possible to output a trigger by setting.Due to internal wiring, sound to the condenser microphone also passes through Onset Analysis. If you do not want to record with Onset Analysis, lower Sense or change Onset behavior with Shift+Capture+Layer (see Onset Analysis Setting below).

Input ismono/stereoIt is possible to switch.Switch by pressing Shift and Capture while turning the Grain window (described later) or by using a preset file.For stereo, the Onset input becomes the R input.Turn on the Analog Emulation option in the preset file to apply the same process to the input as the analog limiter installed on input L.

Output Section

The granularly processed audio is mixed with the original sound using the Dry/Wet control, passed through the Output Level, and output from the two Output jacks.If you want to output in mono, patch only to Output2.When patched to both, the signal is output in stereo, and by default each grain is randomly swung left and right using coin toss logic.

The phase of the signal from Output 2 can be reversed for a unique cancellation effect when converted to mono.Changes can be made by holding down Shift and Capture while turning Hold (described later), or from the settings file.

Grain Playback

In Arbhar, besides the internal trigger whose frequency is determined by Intensity,StrikeThe input allows you to trigger grains externally and mix them into the output.Each grain can be played polyphonically, and the total number of notes that can be played is 88 for the internal and external triggers.The pitch of each grain is affected by the 1V/Oct input, the pitch knob, and the Pitch Deviation control;Only updated at the moment of pronunciation(Sample & Hold), pitch control in the middle of pronunciation does not affect the grain.This allows for polyphony with distinct pitches for individual grains.

Follow Mode
With Arbhar's default settings, if the Scan control is constant, the grain playback position will not change, but if you switch to Follow mode, the playback position will automatically move, and Scan will control the movement speed. Follow mode is, can be switched by pressing Shift and Capture while turning Scan or by using a settings file. In Follow mode, the Strike button lights up white.

In Follow mode, buffer playback will be looped when Follow Mode Looping is On.The setting is ON by default, and ON/OFF can be switched in the settings file.The length of the loop can now be controlled with the Hold knob.When looping is enabled, the speed control by Scan is bidirectional, and rotating to the left of center will play in reverse.

Wavetable Mode

Turning the Length knob fully counterclockwise will bring the grain playback length closer to audio rate and crossfade into Wavetable mode.The generated wavetable is made from single-cycle loops of recorded content within layers.Both Grain Direction indicators will light amber when this mode is active.

  • The pitch of the Wavetable Synthesis Engine is calibrated to produce a C note when the Pitch knob is set to the center position.
  • The Pitch Deviation knob works as usual.
  • The Scan and Spray knobs change the position within the layer from which the wavetable is derived.
  • Turning the Intensity knob to either extreme position disables continuous vibration.At any of these extreme positions, you can trigger short notes using the Strike button and Strike input.These notes are 15% louder than continuous vibrations and can be used to emphasize continuous vibrations.
  • Turning the Grain Direction knob affects the interpolation speed between wavetables derived from the recorded content within the layer.
  • By default, the wavetable center frequency is C2, 130.813Hz.
  • The center frequency can be set in the configuration file.


Recording is started and stopped by the Capture button, trigger input, and Onset Analysis.One layer (buffer) can record up to 10 seconds.If you start capturing and do nothing, recording will continue until the end of the buffer.Recording continues even if you change the playback layer midway through.Pressing Capture again during recording will stop recording.

You can change whether the gate input to the Capture jack is latch (turns capture ON/OFF with the gate) or momentary (captures only during gate High) by holding down Shift and Capture while turning Dub (described later), or by using the settings file. Is possible.You can also switch whether to press or release the capture button to start recording using the settings file.

There are 6 available layers from α to ζ for recording.LayerSelect by control. An Ω buffer that combines six can also be selected.In Ω bufferYou can select and play α to ζ using the Scan control.Also, the color of the buffer display changes for each layer.

Accumulative Recording Mode
By default, recording always starts from the beginning of the buffer, but you can resume recording from where you left off.Accumulative Recording Modeis also possible. This can be done by holding Capture and pressing Shift or by using a configuration file.When recording is stopped in this mode, the Capture button will flash amber.The recording position is automatically reset to the beginning of the layer when the recording head is paused past the 10 second mark.To manually reset the recording head, double-tap and hold the Shift button to enter Track and Hold mode, then press the Capture button.

Additionally, it is also possible to manually set the recording head to a specific position.
To do this, set the Scan knob to the desired position and double-tap the Shift button to
Press and hold to enter Track and Hold mode and press the Strike button.

The input sound can be recorded repeatedly in the buffer. How much of the existing sound is left after a new recordingOakAdjust with controls. Also press Shift + Capture + Strike to activate the current buffer state.savecan. If you don't like the new recording, press Shift + Strike to go back to the previous recording.undoTo do. If you repeat this, the buffer will be empty at the end, but press Shift + Strike again in that state to save the saved contents.Roadcan. This save function is very convenient when you want to return to the past buffer state after experimenting with various things while overdubbing.

Layer decoupling
Arbhar allows you to specify separate layers for recording and playback layers. You can change only the recording layer (LED amber) while keeping the playback layer (LED white) by turning the Layer knob while pressing Shift. When you select the Ω layer, the playback layer and the recording layer will match again.


In Arbhar, by using the Track&Hold function, which involves pressing Shift twice before operating a knob or button, you can operate the parameter so that the changed parameter becomes effective only when you release Shift. Press Shift twice and the buffer display will turn green to indicate Track&Hold mode. Grain Window, Pitch, Pitch Deviation, and Intensity are the parameters that can be tracked and held.Among them, Pitch can be set while track and hold to adjust the pitch.QuantizeThere are functions that can be performed.At that time, the pitch will be displayed using the layer indicator as shown below.

+1 (-11) Semitone: White alpha - B
+2 (-10) Semitones: White beta - A#
· · ·
+5 (-7) Semitones: White epsilon - G
+6 (-6) Semitones: White zeta - F#
-5 (+7) Semitones: Amber beta - F
-4 (+8) Semitones: Amber gamma - E

-1 (+11) Semitone: amber zeta - C#

Expander and Hold CV

The expander is equipped with CVin of Spray, Layer, Direction, Envelope, Pitch Deviation, Dub, Hold, Dry/Wet.However, the Hold CV input can be changed to any of the following controls using the preset function:

  • Stereo Panning: Controls stereo width and panning movement using CV values. Increasing the CV from 0 will narrow the panned stereo width. Moving the CV in a negative direction changes the panning from a simple coin toss to something more random.
  • Hold CV: Controls the CV of the Hold parameter.
  • Stereo Reverb: Control the amount and parameters of reverb using the CV value. When CV is positive, it controls the reverb parameters, and Dry/Wet is fixed. Inputting 5V will freeze the reverb.When negative, only the wet signal is output, making it possible to obtain a shimmer effect.
  • Delay: Controls the amount of delay and parameters using the CV value.When the delay is mono input, Out1 outputs a dry signal and Out2 outputs a wet signal.When inputting stereo, a fixed Dry/Wet mixed signal is output. When CV is positive, the feedback is fixed at 66% and the delay time is changed from 80ms to 1000ms.When negative, the delay time is 25ms-1ms, and the feedback is 99%, creating a Karplus-Strong effect.

Trig Out & Onset Analysis Setting

You can change the Trig Out and Onset Analysis settings by holding down Shift+Capture and turning the Layer knob, or from the settings file.

  • alpha: Recording is triggered by onset detection of the audio signal.For each grain generated, a trigger signal is generated at the Pulse Output.
  • beta: Recording is triggered by onset detection of the audio signal. A gate signal is generated at the Pulse Output and remains HIGH for the period set by the Hold Knob.
  • gamma: generated GrainA trigger signal is generated at the Pulse Output.An additional trigger signal is generated during onset analysis.
  • delta: A gate signal is generated at the Pulse Output and remains HIGH for the period set by the Hold Knob. It is useful to connect the Pulse Output to the Capture Pulse Input and set the Hold Knob to the same time period as the recording period.
  • epsilon: Pressing the Strike Button generates a trigger signal on the Pulse Output.
  • zeta: When playing in Follow Mode, an End of Loop (EOL) trigger signal is output from the Pulse Output at the end of the set loop time (Hold Knob).

When using stereo input, the Onset input recording trigger function is disabled, so alpha is the same as gamma, and beta is the same as delta. 


Arbhar file structure
In Arbhar v2,

  • Various setting items including those set with button combos
  • Audio data contained in 6 layers

can be saved/recalled.The settings are stored in a text file called ****.txt, and the audio is stored in the form of a wav file.A collection of settings and 6 audiosscene, and one scene is stored together as one subfolder.Six scenes are stored in the main unit even when the USB is not inserted, and you can switch between them by selecting from the Load/Save menu below. A USB can store 1 banks each containing 6 scenes.It is also possible to change only the settings in the Load Configuration settings in the scene settings file and not change the audio content of the layer.In this case, only the preset will be recalled.

Presets inside the main unit
The scenes stored in the main unit are determined by the Load Configuration settings described above.Settings onlywithout changing the layer's audio content.Used to change only setting items at once to suit various uses. Presets 1 to 6 are as follows.For details on how to load, please refer to "Calling a scene" below.The complete parameter content of each preset ismanualFrom page 63 onwardsDefault Presets".

  • Preset1:  This is a preset with specifications close to Arbhar Classic firmware V1. Mod CV is set to reverb

  • Preset3 Arbhar Stereo: Preset assuming stereo input. Onset mode is changed to delta
  • Preset4 Follow Mode: Preset for follow mode where the playback position advances. Capture CV mode is set to Retrigger, and the playback position will be reset each time Capture is triggered.Also, the Onset mode is set to Zeta and the Quantize table is changed to Octave. Mod CV will be changed to Hold.
  • Preset5 Panning Mode: Mode for panning mono input. Mod CV becomes panning, and Onset mode becomes gamma.
  • Preset 6 Accumulative Recording Mode: An additional recording mode that basically records from the middle of the layer. Onset mode is delta

List of folders in USB
The USB consists of the following folders.

  • _arbhar_library: A folder for storing samples to be loaded into layers. Up to 6x6=36 subfolders named (bank number)_(layer number)_sample can be stored, and each subfolder stores one wav file. If there are multiple files shorter than 1 seconds, they will be collected and arranged on a layer so that the length is 10 seconds.
  • _arbhar_scenes: A folder for storing and recalling scenes. (Bank number)_(Scene number)It can store up to 6x6=36 subfolders named _scene.Each subfolder contains a .txt file with settings and 6 wav files to load into the layer..

    List of setting items

    For example, the settings for the parameter CaptureButtonMode in the configuration file are as follows. /* ... */ are comments that contain explanations about the parameters.The actual code is only the PARAMETER: CaptureButtonMode: 0 part, so if you are creating from scratch, you only need to write that part.If you want to refer to the factory preset file Arbhar.txtClick here for the guidelines..

    Capture Button Modes: Latching or Momentary
    arbhar's Capture Button can be set to Latching or Momentary Modes.

    Latching Modes will activate recording when the Capture Button is pressed and deactivate
    recording when the Capture Button is pressed again.

    Momentary Mode will activate recording as long as the Capture Button is pressed and will
    deactivate recording when the Capture Button is released. This behavior might be more
    appropriate for certain use cases, including capturing shorter samples when using the
    Accumulative Capture Mode.

    0 - Latching (Default)
    1 - Momentary

    Note: This parameter might overwrite the 'Activate Capture On Button Up' parameter.

    PARAMETER: CaptureButtonMode: 0

    The list of parameters that can be changed in the settings file (****.txt in the scene subfolder) is as follows.

    PARAMETER: Load Configuration: Presets, Layers, and Scenes:
    When loading a scene, arbhar allows you to choose between presets, layers, or the entire scene.

    •  Preset reads all parameters defined in the configuration file and ignores audio files present in the _arbhar_scene directory.This option is equivalent to having only configuration files in the directory.This is the factory preset setting.
    • Layers loads the first six audio files present in the _arbhar_scene directory and ignores all parameters defined in the configuration file. The arbhar control behavior remains the same, but the layer's audio file is replaced.This option is the same as if the directory contains audio files but no configuration files.
    • Scene will read all parameters defined in this configuration file and the first six audio files present in the _arbhar_scene directory.

    PARAMETER: InputMode:
    arbhar can function in both mono or stereo input mode.In stereo input mode, the input is the left input and the onset input is the right input.The sensitivity knob acts as a level control for the onset input.

    PARAMETER: AnalogEmulation:
    arbhar allows for analog emulation of onset inputs to equalize left and right sound quality in stereo input mode.

    PARAMETER: PhaseSwitch:
    By default, arbhar's Output 2 is inverted in phase from Output 1.
    •If you want mono input/mono output patching, set Phase Switch to phase-inverted.If you want mono input/stereo output patching, set Phase Switch to phase correction.If you want stereo input/stereo output patching, set Phase Switch to phase-corrected.

    PARAMETER: CaptureCVMode:
    Arbhar's CV capture behavior can be set to one of three capture modes: Momentary Capture Mode, Latching Capture Mode, and Retrigger Capture Mode.
    • Momentary Capture Mode records while the signal at the Capture Pulse Input remains HIGH.This is best used with gate signals.
    • Latching Capture Mode starts recording when a rising edge signal is received at the Capture Pulse Input and continues recording until another hard edge signal is received.This is best used with trigger signals.
    • Retrigger Capture Mode restarts recording whenever a rising edge signal is received on the Capture Pulse Input, but does not interfere with the state of the capture.

    PARAMETER: CaptureButtonMode:
    arbhar's Capture Button can be set to Latching mode or Momentary mode.
    • Latching mode starts recording when the Capture Button is pressed and stops recording when the Capture Button is pressed again.
    • Momentary mode starts recording while the Capture Button is pressed and stops recording when the Capture Button is released.This behavior may be suitable for certain use cases, such as when capturing short samples using Accumulative Capture Mode.

    PARAMETER: ActivateCaptureOnButtonUp:
    You can set it to record when you press or release a button.
     By default, pressing the Capture Button starts recording.This parameter can be changed and recording can be set to start when the Capture Button is released.This behavior may be suitable for certain use cases, such as when using Accumulative Capture Mode or using the built-in condenser microphone to minimize button noise recording.

    PARAMETER: AccumulativeCaptureMode:
    This mode allows you to successively combine different recordings at different positions within a layer.When enabled, pressing the Capture Button will pause the record head instead of resetting to the start of the layer.

    PARAMETER: LinkAccumulativeRecordingCaptureAsGate:
    arbhar can be configured to link Accumulative Capture Mode and Capture Button Mode.This allows a link to activate Capture Button Mode when Accumulative Capture Mode is enabled.

    PARAMETER: OnsetMode:
    Arbhar features six Onset Control modes that analyze significant spectral changes in the input audio to estimate the onset of new sound events.These modes are alpha, beta, gamma, delta, epsilon, and zeta.

    PARAMETER: StrikeButtonToTrigger:
    arbhar can configure the Strike button to generate a trigger signal on the Pulse Output when pressed.If this feature is disabled, pressing the Strike button will not generate a trigger signal on the Pulse Output.If this feature is enabled, pressing the Strike button will generate a trigger signal on the Pulse Output

    PARAMETER: StrikeCVDelay:
    Arbhar can be configured to apply a trigger delay to Strike Input.This defines the time added to the Strike Input delay time.Adjusting this delay is useful for improving sample-and-hold accuracy when the trigger signal occurs before the CV.

    PARAMETER: FollowMode:
    Arbhar can be set to either Scan mode or Follow mode.
    • In Scan mode, move through layers with the Scan knob, set playback position at any point, and freeze audio playback.
    • In Follow mode, audio playback is internally triggered and directed, and the Scan knob becomes the speed control at which the recorded grain progresses.This mode allows you to change the playback speed of a layer independently of the pitch control. The Scan knob controls speed from 20x (fully counterclockwise) to 1/20th (fully clockwise).

    PARAMETER: FollowSpeedDirection:
    Arbhar allows you to configure the behavior of the playback speed control (Scan knob) in Follow mode.
    • With Unidirectional, the playback position is only forward. Playback speed is slowest when the Scan knob is set fully counterclockwise. Playback speed is fastest when the Scan knob is set fully clockwise.
    • Bidirectional sets the playback position to move forward or reverse. When the Scan knob is set to the center position, the playback speed will be the slowest. When the Scan knob is set fully clockwise, playback speed is fastest in the forward direction. If the Scan knob is set fully counterclockwise, playback speed will be fastest in reverse direction.
    • With Inverted Unidirectional, the playback position is only forward. Playback speed is fastest when the Scan knob is set fully counterclockwise. Playback speed is slowest when the Scan knob is set fully clockwise.This is the same as unidirectional, but the behavior of the Scan knob is reversed.

    PARAMETER: FollowScanOffset:
    Arbhar allows you to set a Scan offset in Follow mode if the Follow mode playback speed is set to be controlled by the Scan knob and the Scan CV input.

    PARAMETER: FollowPositionOffsetWithScanCV:
    Arbhar allows you to configure the behavior of the Scan knob and Scan CV input in Follow mode. The Scan knob and Scan CV input can be set to control playback speed, Scan offset, or both

    PARAMETER: FollowLoop:
    Arbhar can enable or disable playhead loop playback in Follow mode.
     Note that if Follow mode looping is set to disabled, the bidirectional option for Follow mode speed control will also be omitted and automatically set to unidirectional.

    PARAMETER: FollowSetLoopLengthWithHold:
    Arbhar can control the length of loop playback in Follow mode with Hold.The end of layer (EOL) trigger signal is triggered at scan offset in Follow mode and can be looped during the hold period.This is the same EOL trigger signal available in zeta Onset Control mode.

    PARAMETER: RandomTimingWithRandomIntensity:
    Arbhar allows you to set random timing of grains.
    Random timing of internally triggered grains can be applied by turning the Intensity knob from the center position to the fully clockwise position.

    PARAMETER: RandomAmpWithRandomIntensity:
    Arbhar can randomly set Grain's new clothes. By turning the Intensity knob from the center position to the fully clockwise position, you can apply a random amplitude of internally triggered grain.

    You can set the Mod CV Input target.

    PARAMETER: WavetableCentreFrequency:
    You can set the center frequency of Wavetable mode in Hz.

    PARAMETER: QuantiseTable:
    The clockwise behavior of the Pitch Deviation knob sets the available pitch variation. Each clockwise step of the Pitch Deviation knob uses the pair of numbers in the list and the "original" pitch set by the Pitch knob as the Pitch Deviation parameter.
