Re: Unwanted Percussion Sounds
G'day John,
if you check the staff properties for those instruments you'll find on the MIDI tab that they're assigned to channel 10.
This is the percussion channel - you simply can't use it for anything but percussion.
If you've run out of channels, you can use the same channel for some groups of staves:
E.G. 1st and 2nd violins can often share a channel - all the Horns can usually use the same channel &etc.
