I'm interested in using a noise gate somewhere in my pedal chain to get a choppier synth sound. I don't need it to reduce noise, just to cut off the decay of notes. Sort of like adjusting the "Sustain" and "Release" of an ADSR envelope on a synth. The Boss NF-1 looks like it fits the bill - it has controls for attack and decay. Has anyone used a noise gate (the Boss in particular) for this purpose?
