It's a little different than the MP3 route because I can customize my own arrangements, fills, etc. Kind of like Band in a Box, where you enter in the chords and select a pattern/chain of patterns. Also, it's just bass and drums - no other instruments which I think the mp3s would have.

And it uses all of the SRX sounds. I have always loved Roland's SRX expansion boards (including the incredible Complete Orchestra) and from the demos I've heard of the DR-770 and the 880 the bass and drums should be incredible.

Should take me a couple of beers and around 5 songs a night to put in all the changes. I should be ready to roll in a couple of weeks.

I will definitely post some mp3s of the new combo.

Again, thanks for all the suggestions.
