Kurzweil PC4 - Assigning Pressure with an ASR

On most keyboards, aftertouch (monophonic pressure) can be very unwieldy, and can cause abrupt jumps to whatever it's assigned to affect. One cool workaround is to use aftertouch to trigger an ASR, and then let the ASR do the work. (An ASR is a very simple envelope, with attack, sustain, and release - it's a shape that can affect parameters over time.) Once you lay into the keys, the pressure will trigger an ASR to ramp up smoothly. This is very handy for things like volume swells, filter sweeps or controlling the depth and/or rate of an LFO vibrato. More info and demos here: www.weisersound.com
