Biggest problems - The
timing is too perfect, volume is too perfect, pitch is to perfect ; and this leads to unnatural sounding performances.
Timing, pitch, and volume sway in a live instrument performance.
1) Yamaha WX5 is one answer to your problem (Just play in a few lines - mix with keyboard tracks).
2) Someone already said one live player on top of the mix.
3) Score for a High School Stage band - ALL LIVE performances!
Yamaha WX5 is what I use for horn stuff. It's not a cheap solution, but it works great. I have a friend Larry that can do all the stuff I do on a WX5 on a keyboard - I never have that kind of ribbon / pitch wheel skills.
