Vostok Instruments Sigma Hybrid Rhythm Computer

Sigma is a multi-channel gate processor with a strong focus on rhythm and time-event manipulation.

The module generates up to 23 simultaneous gate signals directly related to the four gate inputs, allowing you to fire an entire array of synced events in your patch by just moving pots and connecting cables.

The core of the module is composed of four identical CV-controlled gate-length processors that create exact copies of your gate signals with adjustable length.

The Logic section creates new events from each length-processed pair using analog Boolean circuits.

Pair Sigma with a trigger sequencer or clock generator, and a bunch of drum modules or voices to get a vast amount of new rhythmical patterns on the fly.
