similar deal for me...
wilfoster,
I've been doing pretty much the same thing with CEP (from old Tascam Porta0?). I usually try to record as hot as possible without audible (or otherwise I guess) clipping. Depending on what you have on your 4 individual tracks, I guess how you dump it into your PC is a matter of taste...I have done all 4 into seperate stereo files and mixed in multitrack but it was a bitch syncing these up...result was good but extremely labor intensive (time stretch feature is cool but I still haven't gotten proficient at it). Don't know SF too well so I guess I'm not throwin ya too much here...it is fun though, ain't it?
Anyway, good luck...
