it seems to work with with a limited number of instruments and as i said it removes the drums.
i am tying to create a backing track true to the original song so that i can play a transcribed original sax. solo. obviously when i create a backing track using styles in biab and play a transcribed solo it never quite matches.

one problem is i only seem to be able to edit the note channel numbers one at a time.

but the main problem is adding a new drum part. i tried adding notes to the drum part they are there but don`t play back any ideas.

culfy
