The Raiju (雷獣) is an 8HP Percussive voice "hidden" inside a combo Vactrol LPG + envelope module.

ADSR Envelope generator
Digital envelope generator with cv control over each stage, three selectable, configurable, ranges, End-Of-Stage output (you can toggle between All stages, Attack, Decay, Sustain and Release) and a shape control pot, going from linear to exponential.

Analog LPG The lpg can be controlled by the internal envelope or an external trig/cv, it's input is normalled to the oscillator, simply plug an external audio source to override it. It uses a vtl5c3/2 vactrol from XVive.

Percussive Oscillator The internal digital oscillator has been developed and fine tuned for percussive sounds, with it's macro-controlled FM Oscillator (noise or sine mod osc with configurable ratio), bandpassed triangle core, a 5-stage, buchla-style waveshaper and pitch envelope. When Raiju is used as a voice you can route the CV inputs to selected envelope or oscillator parameters.
