Doepfer A-143-2

This is a beast of a module.
4 independent ADSR with End Of Cycle outs for Attack, Decay and Sustain.
Gate input 1 is normalled to input 2-3-4 so you can use the same gate to all with just one cable.
You can also patch it up as an AD Loop or an pseudo LFO. Or a daisy chain of envelopes. The possibilities are almost endless.

Good sturdy potentiometers give an robust feel and you won't accidentally nudge a pot.

3 separate timing settings for each ADSR with times from a couple of ms to 5 minutes available.
It quite big and deep so make sure you can fit it in your skiff. But I'd recommend it to anyone.
