Doepfer A-142-4

The A-142-4 Quad Decay from Doepfer generates simple decay envelopes from incoming trigger pulses. With four total channels, the A-142-4 can be very useful for synthesizing multiple percussion voices or achieving simple polyphony in Eurorack. Decay time for each of the four channels is adjustable from 1ms-15ms while attack time is static, making this a very uncomplicated way to introduce more envelopes into a system.
