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.
