L.I.G.O. stands for LFOs In, Gates Out, and is a comparison logic module in the Eurorack modular synthesizer format.
L.I.G.O. provides a tremendous amount of sequence generation potential for minimal input. Just feed it a couple LFOs, and it will provide you with multiple gate patters all relating to those LFOs. It doesn’t need to be LFOs either, patch in sequencer CV as one of the sources, and gates suddenly relate to the pitch of your sequence!
Of course, as a good Eurorack citizen, L.I.G.O. also provides you back buffered versions of your input, so you don’t need a multiple or stacking cables to continue using that CV across the rest of your system.
