heres an alternative for you.
bb is great for fast track generation but realband is superior
by a long shot when it comes to audio and midi handling
and editing.

import your bb song into rb and then you have 255 tracks to
record on plus features like odd time sig handling
and numerous other features. (see the rb manual and my tips on these forums.)

remember you can also drag tracks from bb into rb...
easy peasy.

see various of my many tips in pg tips forum including
how to do things like drum solos.

lots more info in the rb forum also.
