Desmodus Versio

Stereo-in, stereo-out synthetic tail generator reverb and DSP platform. Less of a room simulator, more of a synthetic tail generator with features for sound design and performance. Runs on the Versio stereo DSP platform; firmware-swappable via USB.559

Capabilities 3

Resonatorresonator: Regen past noon reaches 100% feedback (infinite tail); can self-oscillate when FSU is triggered with no input.559
Reverbreverb: Primary function: synthetic tail generator reverb, not a room simulator. Three reverb style modes: LIM (clean limiting), DST (saturating), SHM (shimmer with octave pitch shift).559
Stereo Processorstereo-processor: True stereo in / stereo out; right input normalizes to left when unpatched.559

Jacks 5 — 3 in / 2 out

Parameters 10

Name	Type	Range	Behavior
Blend	knob	—	Dry/wet balance. Fully CCW: dry signal only. Fully CW: wet/processed signal only. Center: mix of both.559
BND/LRP/JMP	switch	—	Controls how delay lines respond to modulation: BND crossfades, LRP interpolates with pitch effects, JMP jumps quickly.559
Dense	knob	—	Controls spacing of delay lines. CCW: delay-like character. CW: delays smeared into reverb.559 Zones Delay Reverb Delay -100–0%Delay lines sparsely spaced — effect sounds like a distinct delay.559 Reverb 0–100%Delay lines densely smeared — effect becomes a lush reverb.559
FSU	button	—	When pressed (or gate input is high above +2V), maxes Regen and mutes the audio input, creating a freeze/swell effect.559
Index	knob	—	Bipolar LFO amount to delay lines. Center: LFO disabled. CCW: random LFO modulation. CW: sine wave LFO modulation. Rate set by Speed parameter.559 Zones Random Sine Random -100–0%LFO modulates delay lines with a random waveform.559 Sine 0–100%LFO modulates delay lines with a sine wave.559
LIM/DST/SHM	switch	—	Selects reverb style: LIM (clean limiting), DST (saturating/distorting), or SHM (shimmer with one-octave pitch-shifted feedback).559
Regen	knob	—	Controls feedback in the reverb tank. Fully CCW: minimized feedback. Up to 12 o'clock: shorter reverbs emulating smaller synthetic spaces. Past 12 o'clock: 100% feedback, infinite tail. Past 3 o'clock: infinite reverb is ducked by new input sounds, creating sidechain-type effects.559 Zones Short Reverb Infinite Tail Sidechain Duck Short Reverb -100–0%Feedback minimized to moderate; shorter reverbs emulating smaller synthetic spaces.559 Infinite Tail 0–50%100% feedback — infinite tail with no ducking.559 Sidechain Duck 50–100%Infinite reverb tail is ducked by new sounds arriving at the input, creating a sidechain-type effect.559
Size	knob	—	Controls the delay time of the reverb, affecting the perceived room size.559
Speed	knob	—	Controls rate of the internal LFO that modulates the delay lines. Modulation amount is set by the Index parameter.559
Tone	knob	—	Bipolar filter in the reverb tank. CCW controls a lowpass filter, CW controls a highpass filter, center disables the filter.559 Zones Lowpass Highpass Lowpass -100–0%Lowpass filter applied in the reverb tank, increasing in strength toward fully CCW.559 Highpass 0–100%Highpass filter applied in the reverb tank, increasing in strength toward fully CW.559
