lochan / hichan
If incoming notes have a MIDI channel between
hichan, the region will play.
hichan will almost always be used together.
One application of this is SFZ files which are to be controlled from MIDI guitar
controllers, which send MIDI data for each string on a separate MIDI channel.
The regions for that string would then have
hichan set to the
lochan=1 hichan=7 lochan=2 hichan=2
