Stereo In/Out Synthetic Tail-Generator Reverb and DSP Platform

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 DV 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 DV a unique reverb, it’s a stereo DSP platform. A simple USB connection will allow you to update DV to a variety of future effects firmwares. Open-source support will be released near the end of the year, too, which will allow you to write your own firmware!

Features
• All CV inputs expect 0-5v. All pots act as offsets and sum with the input CV. The FSU gate input responds to signals above +2 V.
• 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 high pass filter. In the center, the filter is disabled.
• Regen: Amount of feedback in the reverb tank. Regen controls a wide range of tones and behaviors. All the way to the left, feedback is minimized. As you turn up to about 12 o’clock, DV 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 side-chain 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.
• Index: The amount of LFO sent to the delay lines that make up the reverb. This is a bipolar control: in the center the LFO is disabled. To the left, the LFO modulates the delay lines randomly. To the right, the LFO modulates the delay lines with a sine wave. The Speed parameter controls the rate of the LFO.
• Size: The delay time of the reverb.
• Dense: The spacing of the delay lines. To the left, the effect sounds more like a delay; to the right, the delays are smeared into reverb.
• 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.
• 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 mode clearly, turn Regen fully clockwise and modulate the Size parameter.
