Qu-Bit Electronix Nebulae v2

Phase-vocoder granular sampler and open DSP platform

20 HP Eurorack module

Nebulae v2 is a stereo granular sampler and open DSP platform from Qu-Bit. Its phase-vocoder engine time-stretches and pitch-shifts audio independently, while a parallel granular processor shreds the same buffer into grains you sculpt with density, overlap and window controls. The Blend knob crossfades the two engines. Source material can be a USB audio file, a live input, or a 5-minute recorded buffer (48kHz/24-bit). Holding Source unlocks a deep secondary-function layer, and holding the Speed encoder loads alternate instruments written in Csound, Pure Data and more.

Features

  • Phase-vocoder time-stretch engine: change speed independent of pitch
  • Independent pitch shift (-3 to +2 octaves) with 1V/oct tracking
  • Granular processor with density, grain size/overlap and 7 window types
  • Blend knob morphs between phase-vocoder and granular engines
  • 5-minute stereo recording buffer at 48kHz / 24-bit with overdub
  • Plays .wav/.flac/.aif files from USB (up to 75MB, no naming convention)
  • Live, file, or recorded-buffer source material
  • Open DSP platform: load Csound, Pure Data, SuperCollider, shell, C or Python instruments
  • Factory alternate instruments: One-Shot Sampler, Synth Voice, World of Echo, Test IO
  • Secondary function layer accessed by holding the Source button
  • Per-grain randomisation: position, panning, displacement, size, muting and FM
  • Circular (continuous) recording mode via Source+Record

How-To Guides

  • Load a sample from USB and play it
  • Time-stretch a loop without changing pitch
  • Build a granular cloud
  • Record and mangle live input
  • Externally trigger grains rhythmically
  • Load an alternate instrument (e.g. reverb)
