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.
Granular synthesis by Lexer method
Two types of granular engines can be used: one that controls the intensity and grain length, and the other that triggers the grain from the outside.
Scan mode that specifies the grain playback position with CV, Follow mode that automatically plays at an adjustable speed
Can be used like a wavetable oscillator when the grain length is short
Equipped with 10 sample buffers of about 6 seconds. The buffer contents remain even when the power is turned off.
Built-inPanel-accessible condenser microphone
Equipped with analog preamplifier at the input stage
Equipped with audio analysis function that can automatically start capture (recording)
LED display showing audio size, length, playback position and spread
Trigger output whose settings can be changed flexibly
Grain playback direction probability can also be set
Internal pitch modulation possible
1V / Oct input installed
Dynamic control of grain playback window
2HP expander (included with the main unit) allows CV control of not only main parameters but all parameters
HOW TO USE
The role of each part is displayed by mouse over.
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 by changing the position of the switch on the Arbhar body board:
Stereo Panning: CV value controls stereo width and panning movement
Reverb: The CV value controls the amount and parameters of the reverb. Reverb mode uses a lot of the processor power, so the sample rate drops from 64kHz to 48kHz, and the number of grains that can be sounded simultaneously by the internal trigger drops from 24 to 20.
Delay: The CV value controls the amount of delay and parameters.
At Arbhar,Main input jack, Onset Analysis input jack, built-in condenser microphoneYou can record sound from three input sources ,. 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 the spectrum of the input sound, and when there is a large change,Automatically trigger recordingTo do. Due to the internal connection, the sound to the condenser microphone also passes through the Onset Analysis. If you don't want to record with Onset Analysis, lower Sense or change the behavior of Onset with Shift + Capture + Layer (see Onset Analysis Setting below).
On granular processors, the audio in the buffer isGrain) And control various playback methods to create various sounds and textures. Arbhar has various parameters for controlling grain, and almost all can be controlled by voltage. Grain playback position, spread, level, etc. traverse the moduleLED displayWill be reflected in the display.
The playback frequency of the grain internal trigger isIntensityControlled by. The playback timing also changes on the left and right sides of the knob. The envelope that controls the volume of each grain is alsoCoverIt is controlled by the knob and CV. On the bufferScanCentered on the position controlled bySpraysThe grain in the range determined by is triggered. The time length of the reproduction grain isLengthIs controlled by and the playback direction isDirectionIt is stochastically controlled by the knob.
Polyphony In Arbhar, besides the internal trigger whose frequency is determined by Intensity,StrikeThe input can trigger the grain externally and mix it with the output. Each grain can be polyphonically pronounced, and the number of notes that can be produced is 24 for internal trigger grains and 20 for external trigger grains. The pitch of each grain is affected by the 1V / Oct input, pitch knob, and 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 does not change, but if you switch to Follwo mode, the playback position will automatically move, and Scan will control the movement speed. To switch to Follow mode, hold Shift + Capture and turn the Scan knob twice left or right. The Strike button glows white in Follow mode.
Recording is started / stopped by the Capture button or trigger input, and Onset Analysis. One layer (buffer) can record up to 10 seconds. Recording always starts at the beginning of the buffer. There are 6 available layers to record from α to ζ.LayerSelect by control. An Ω buffer that combines six can also be selected.
Overdub 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.
Trig Out & Onset Analysis Setting
You can change the settings for Trig Out and Onset Analysis by holding Shift + Capture and turning the Layer knob.
α: Default setting. Trig will output a gate each time the grain is triggered and Onset Analysis will work as normal.
β: Trig outputs the gate during the hold state by Onset Analysis. Onset Analysis works as usual.
γ: Trig outputs the gate when the grain is triggered and held by Onset Analysis. Recording by Onset Analysis is not performed. Useful when you want to disable automatic recording without changing the position of the Sense knob
δ: Trig outputs the gate during the hold state by Onset Analysis. Recording by Onset Analysis is not performed. This is convenient when you want to use Onset Analysis regardless of the operation of Arbhar itself.
