NI has a new Cuba product which has percussion, bass, piano, tres and trumpet... but no trombone. It's discounted 50% for the next week, and it looks like it would be a good match - it uses samples and a pattern grid (with a lot of presets), so it's got more flexibility than loops.

NI also has Session Horns on sale at 50%, which does has a trumpet and trombone... Only they don't work in solo mode (grrr).

BiaB has MIDI drums where you can set up patterns, but RealTracks are so easy to use that it's been years since I've looked into that functionality. But it might be something worth looking into, especially if you're got a good sampled drumkit.

Of course, you're request is 100% right. Having RealTracks would be great for you. smile

Vocal control, you say. Never heard of it. Is that some kind of ProTools thing?
