Thanks guys. I will look into the monkeyaudio. I hope you do write tips on this rharv. Russ, I don't think I could send the .seq because he doesn't use RB. Mike, I usually do 192 mp3's so I will keep that in mind. John, I hadn't even thought about bit rates. Do I need to know what bit rate he's using?

I'll be using RB and I think he's using recent version of cakewalk music creator.

So when I sing to his mp3 opened in RB, then I should send him back a separate mp3 (or ape file) of each vocal track. I'm assuming I should send him raw tracks with no effects so he can add those on his end.

These will then decompress into his daw so that he can mix it with the original tracks. Then after he does his final mix and recompresses back to an mp3 it should sound decent (depending on how well it was recorded and mixed of course).
