Gate 2 Trigger/decay generator Eurorack Module
Converts (almost) any incoming signal into a trigger with adjustable decay length (For a sustained gate input, the module only triggers once, no stuttering)
Up to minutes in length depending on the electrolytic capacitor used (A 1uf electrolytic capacitor delivers +/- half a second at max setting)
It even responds to audio very accurately, making it a useful clock/signal-extractor, for use with e.g. drum tracks.
Controls: Trigger length, manual trigger. Input: Gate/signal in, Output: trigger out. 6.3 HP. (+/-3 cm)
