Thanks for your interest, Trebor.
What I really need is to convert the first part of that waveform into a short pulse… but (and there’s aways a “but”) … I can’t just turn the whole drum hit into a simple square wave of maximin amplitude - I need to keep the dynamics of the playing so the short pulse I end up with will vary with amplitude and that will drive the level of the resulting drum sample from the Alesis D4 drum module.
Actually, Steve’s NY Noise Gate has both settings available under the hood. That’s the gate I’ve already been using getting rid of microphone spill, and it’s done a good job from a musicallity sense.
and is a simple mod to make them available independantly.
I attempted
THRESHOLD: -26db
ATTACK: 0.20ms (yes, 200 microseconds - I went under the hood and adjusted the range)
RELEASE: 10ms
and even if I go under the hood again and reduced the RELEASE time to, say 2ms, I’ll still have a problem where it will see the next positive swing after 2ms and let that through when I actually want to truncate it. That’s where a “HOLD” setting could come in handy.
OPEN the gate on the initial hit
RELEASE the gate after, say 2ms
HOLD it closed for, say 76ms, ignoring any condition to open it again until that 76ms
I almost need an ADSR envelope applied to each drum hit… hmmm…
