The CV to Gate module provides the ability to take any control voltage and create a gate signal based on the voltage going above a trigger voltage and falling below the release voltage. The trigger is sensed against the set voltage on a rising signal and the release is sensed against the set voltage on a falling signal. The thresholds can be separate or synchronised (set to the same value) using the Sync switch.
At its simplest, this allows gate, trigger and release triggers from clock sources, but it can also be used with any source such as an LFO or random signal to generate triggers/gates or even to generate audio frequency pulse waves.
