Re: Percussion
what is a "MIDI channel"?
"MIDI Channel" is an arbitrary contruct of the MIDI Specification.
If you press F2 on a staff, click on the Midi tab, click on the ? (upper right corner), then click on Channel, you get this:
This specifies which channel on the specified device should be used for playback of this staff.
MIDI devices can support up to 16 channels. Each channel generally uses its own instrument patch, volume, and various other performance parameters. It is usually necessary to use unique channels per staff so that one staff does not interfere with the playback of another staff. By default, each new staff is assigned a new, unique channel.
I would add that channel 10 is usually percussion and that it would help if NWC would skip it when assigning "a new, unique channel".
