SK880user. Thanks for the reply. That's what I think is going on also. The audio from the arranger section is getting routed through the dsp's. You may be on to something if you can select a dsp for the arranger and a dsp for the mic/line input. Your second suggection is probably the most realistic and that is to record in seperate tracks. I've used that process for years when I used to compose and record completely within the PC using cakewalk. I always do the vocals last and that may well be a better way to do it due to the fact that you can then concentrate on singing instead of playing and singing. Its just nice to have the option to go either way. I've got the manual here at work so I can referrence it. Now where did I put my glasses...
