Caveat: I admit to knowing almost nothing about Midi.
But I thought it was programming code that includes, among other things, instructions for each instrument.

If I import a Midi song within BiaB, is there a way to mute one of the instruments when I play (or export) the song?
It would be very helpful for my students if I can 'take out' the bass part of a song.
I've tried what I'd think are the easy 'obvious' solutions but it hasn't worked.

Possible? Is this a real easy task that I'm going to be very embarrassed about when it's revealed?

Thanks.
