Noise Engineering Desmodus Versio Eurorack Stereo Reverb and DSP Platform Module
Noise Engineering Desmodus Versio - Stereo Reverb and DSP Platform
Desmodus Versio is Noise Engineering's long anticipated take on a reverb. This is a true stereo in / stereo out or mono in / stereo out effect. Less of a room simulator and more of a synthetic tail generator with features designed for sound design and performance, the parameters on Desmodus Versio allow you to take the effect from a delay to a beautiful reverb to an uncanny, nightmarish atmosphere in the twist of a few knobs. Not only is Desmodus Versio a unique reverb, it's a stereo DSP platofrm. A simple USB connection allows you to update Desmodus Versio to a variety of firmwares. Open-source support is available too which allows you to write your own firmware.
All CV inputs expect 0-5v. All pots act as offsets and sun with the input CV. The FSU gate input responds to signals above +2v. The audio inputs clip around 16v peak to peak.
• Blend: Dry / wet balance control. When turned fully left, the unmodified input signal is passed through. Fully right, only the processed signal is heard. Points in the middle give you a mix of both. A good way to hear Blend is with high Regen values and Tone and Index set to 12 o'clock
• Tone: A filter in the reverb tank. This is a bipolar control: turning the knob to the left controls a lowpass filter, and to the right controls a highpass filter. In the centre the filter is disabled.
• Regen: Amount of feedback in the reverb tank. Regen controls a wide range of tones and behaviours. All the way to the left, feedback in minimized. As you turn up to about 12 o'clock, Desmodus Versio generates shorter reverbs, emulating smaller synthetic spaces. Past this point, the reverb reaches 100% feedback, creating spaces with an infinite tail. Past 3 o'clock, the infinite reverbs are ducked by new sounds at the input, creating sidechain-type effects.
• Speed: The speed of the internal LFO. The LFO can modulate the delay lines, and modulation amount is controlled by the Index parameter. A good way to hear Speed is with a low Size setting, Density and Index fully clockwise and a high Regen setting.
• Index: The amount of LFO sent to the delay lines that make up the reverb. This is a bipolar control: in the centre the LFO is disabled. The the left, the LFO modulates the delay lines randomly. The the riht, the LFO modules the delay lines with a sine wave. The Speed parameter controls the rate of the LFO. A good way to hear Index is with a low Size setting, Density fully clockwise, Speed at 12 o'clock and a high Regen setting.
• Size: The delay time of the reverb. A good way to hear Size is with a percussive input and all other parameters to 12 o'clock.
• Dense: The spacing of the delay lines. The the left, the effect sounds more like a delay. To the right, the delays are smeared into reverb. A good way to hear Dense is with a percussive input, Size fully clockwise and all other parameters at 12 o'clock
• FSU: This control maxes out the Regen control and mutes the input to the reverb when the button is pressed or when a high gate is sent to its input. A good way to hear this button's effect is with Blend above 12 o'clock and a low Regen value
• In L / In R: Audio input. If R is not patched, the signal from L is normalled to both inputs
• Out L / Out R: Stereo output pair
• LIM / DST / SHM: Reverb style
- LIM (Limit): A clean reverb, using limiting within the reverb tank to contain feedback. A good way to hear LIM is with moderate Regen values and starting with all other parameters at 12 o'clock, then playing with Tone and Index / Speed
- DST (Distort): Similar to LIM, but instead of limiting within the reverb tank, slight saturation is applied for a more distorted sound. A good way to hear DST is with high Regen values and starting with all other parameters at 12 o'clock, then adjusting Size and Tone to taste
- SHM (Shimmer): A demonic pitch-shifting algorithm. Adds a one octave pitch shift that feeds back into the input. A good way to hear SHM is with high Regen values and all other parameters at 12 o'clock. Create haunting effects by introducing subtle modulation with Speed and Index.
• BND / LRP / JMP: Changes how the delay lines respond when the panel controls are modulated. To hear each more clearly, turn Regen fully clockwise and modulate the Size parameter.
- BND (Blend): Crossfades the delay times for smoother changes
- LRP (Interpolate): Slowly changes delay line length, has audible pitch shift effects due to the delay lines changing length.
- JMP (Jump): Quickly changes delay line length, for audible and fast changes.
