Qu-Bit Electronix Nano Rand V2

Musical randomness in 4HP with four algorithms

4 HP Eurorack module

Nano Rand v2 is a compact 4HP sample-and-hold, random voltage generator, and analog noise source built around an 8-bit microcontroller. It offers four switchable random voltage algorithms ranging from stepped voltages to audio-rate square waves, and generates musically-related random gate outputs when externally clocked. Its digital core brings a distinctly musical character to aleatoric patching, producing evolving rhythms and unpredictable but harmonically coherent voltage sequences.

Features

  • 4 switchable random voltage algorithms: stepped, LFO, audio-rate square wave, combination
  • Sample and hold with audio and control rate input (range +-8V)
  • Analog white noise output with extremely flat frequency response
  • Internally or externally clocked operation
  • Random gate output with musically-derived rhythmic divisions when externally clocked
  • Rate knob controls rhythmic probability of gate output when externally clocked
  • Unipolar (0V-5V) and bipolar (+-8V) random voltage polarity switching
  • Algorithm switching via front panel button or external gate input (threshold 4.5V)
  • Rate LED indicates active algorithm color and current clock rate
  • Reverse power protection
  • 4HP skiff-friendly form factor
  • 8-bit microcontroller core

Controls & Jacks (16)

  • Gate Out— When internally clocked, outputs periodic gate signals at internal clock rate. When externally clocked, outputs random gate signals derived
  • Rand— Random voltage output. Four algorithms: Magenta (stepped voltages), Cyan (LFO waveforms/frequencies), Amber (audio rate square waves), Green
  • Clk— When internally clocked, acts as CV input to modulate internal clock rate. When externally clocked, acts as gate input for external clock so
  • Noise— Analog white noise output with extremely flat frequency response.
  • Rand Algo— Advances to the next random algorithm sequentially.
  • Rand Algo— Gate input that advances to the next random algorithm. Threshold voltage is 2.5V.
  • S+H Out— Sample & hold output. Range is ±8V.
  • S+H In— Sample & hold input. Accepts both audio rate and control rate signals. Range is ±8V.
  • Bi— Bipolar polarity control input.
  • Rate— Controls internal clock speed (fully left = slowest, fully right = fastest). When externally clocked, controls rhythmic probability of rando
  • Ext— External clock mode trigger input.
