Arbhar heralds a new generation of granular processing in Eurorack. Sampled audio can be chopped into tiny grains, scattered, shaped, re-pitched, reversed, and layered for an endless range of audio manipulation from seamless frozen tones to mutated acousmatic madness. Each grain sounds with its defined specifications. When modulation is used, the “per-grain parameter” definition allows for true polyphonic layering.

Featuring a condenser microphone set into the front panel, built-in audio analysis for automatic sampling, and internal modulation over various parameters; this is truly a granulator like no other.

Introducing the world for the first time to the Dr Lexer methodology of granular processing.

It is as the old saying goes … “Nicht verzagen, Lexer fragen”.


  • Granular processor (Lexer method)
  • Two granular engines available simultaneously:
    1. controlled by intensity and grain length settings (up to 24 grains)
    2. externally triggered grains (up to 20 grains)
  • Manual and automatic playhead control for granular textures and time stretched audio playback (Scan/Follow mode)
  • Sampling wavetable oscillator
  • 6 sample buffers (10 second record time each)
  • Built in condenser microphone
  • Dedicated analogue input pre-amplifier
  • Audio onset analysis for automatic capture control
  • LED display for amplitude, length, scan, spray
