RYK modular did it again. ALGO is a quad complex stereo VCO that will serve both the beginner as the advanced sound explorer.
ALGO's four oscillators can be used to create complex FM or additive sound textures (chords, pads, organs). Obviously this module is digital. A unique Algorithm Display gives an idea of what affects what, and it looks great. In a typical 4Operator scenario, you can use M1 to M4 CV to modulate the volume of each voice, but you can also switch to FM mode and unleash chaos.
The module uses the 'sum of sines' technique to sculpt new sounds, but you can also use Warp and Fold to do traditional waveshaping and folding.
The module offers detuning, chorus and a built in VCA.
