abacus , been there, done that. I have used Band in a Box and One Man Band for years. Band in a Box I have used more, because I don't need a lot of realtime stuff.

As for Live Styler, my God. I uninstalled it after 10 minutes, hated all the numerical values I had to enter and it's complexity.

I'll use the PC only to substitute the sounds after the music has been fully written on the hardware.

Integration? No thanks...it never really worked the way I want, and it never will.
