Granular Pitch-Shifting Effect
Audio Damage ADM02 Grainshift is a pitch-shifting module built with granular synthesis code originally developed for our Discord 3 plug-in.
Granular synthesis divides sound into small segments, or grains, and reassembles them in different ways to produce different effects.
Grainshift offers a simplified set of granular synthesis parameters to bring this powerful signal-processing technique to the modular synthesizer world in an easy-to-use and economical package.
From subtle chorusing to diffuse clouds of sound, Grainshift adds exotic new flavors to your modular spice rack.
Control voltages present at the jacks are added to the values set with the knobs.
Positive voltages at the PITCH jack increase the pitch shift; negative voltages decrease it.
The CV jack adds an additional octave (up or down) of shift to the range available with the PITCH knob.
Positive voltages at the CHAOS jack increase the amount of chaos (pitch randomization); negative voltages decrease it.
Positive voltages at the SIZE jack increase the grain size; negative voltages decrease it.
The useful range of voltage for the CV jacks is ±5V.
The SHIFT knob changes the amount that the signal's pitch is raised or lowered.
Turning the knob clockwise from its center position raises the pitch; turning it anticlockwise lowers the pitch.
The shift range is up or down one octave.
The CHAOS knob randomizes the pitch and size of the audio grains.
Turning the knob clockwise increases the amount of randomization.
The SIZE knob controls the size of the grains. Rotating the knob clockwise makes the grains longer.
Use the SIZE knob to tune the module to suit your source material. Longer grains provide a smoother sound, while shorter grains preserve transients more accurately.
The audio input signal goes in here. The hardware will be happiest if the signal level is within ±7V.
All of the little sonic grains emerge from here.
Help them find their way in the world of your modular system.
A hint of chaos can help smooth the sound out by detuning the grains slightly.
While this can be useful in itself, try mixing a little of Grainshift’s output with CHAOS the original signal to add a background texture.
