Not sure this will help, but I find that I have to watch the key signatures very carefully. If the song is in C, the other instruments will have to match. Like my trumpet is in Bb so I have to add 2 sharps and go up 2 intervals. For the flute things are fine. I think the trombone is in C like the flute. If you load up a tune that has an embedded melody already there, you can't just change the key of the biab song--at least that's what I found. You have to make the key of the other instruments match the key of the song via transposition. Of course you can change everything, if it's a midi file in PowerTracks or Real Band. Not sure if you wanted to hear all of this, but.....
