Instruo Cruïnn
Analogue stereo oscillator with through-zero phase modulation
14 HP Eurorack module
The Instruo Cruïnn is an analogue stereo oscillator built around a single sawtooth core that produces six parallel phase-displaced sawtooth variants. Five internal triangle-wave LFOs independently modulate the phase of each variant, creating super-saw textures, lush stereo pads, phaser-like basses, and chaotic effects. A built-in stereo VCA with soft-clipping saturation provides amplitude control, and both linear and exponential FM inputs are available. The module includes a passive 4HP expander for individual waveform outputs and per-voice CV phase control.
