Polyphony voice limit for a group.
An example limiting a crash cymbal to four polyphony voices, and a ride to a total of seven voices, with the ride group including both the bow and bell articulations:
<group> group=1 polyphony=4 <region> key=49 sample=crash.wav <group> group=2 polyphony=7 <region> key=51 sample=ride_bow.wav <region> key=53 sample=ride_bell.wav
This opcode is useful for controlling sound buildup, limiting resource use, and for emulating the behavior of vintage keyboards with limited polyphony. It’s also possible to use note_polyphony instead when there is only one pitch in a group, or use both in combination. An alternative for controlling sound buildup is using ampeg_release with off_mode set to normal.
