Hi,
Wow that's a lot of programing. And it's all in step record? or did I misunderstood you. I'm more of a "live"recorder so that won't work for me. But if you're gonna do it all in step recording then I think the pa 80 just might be able to pull it off. In step record, you can insert chords as well as your control ( intro, v1,v2, etc) anywhere...I think you can even insert different styles into one song ( like ballad in v1 and rock on v2). You can mute, pan, transpose, etc each track in the mixing page (while in song mode). You can assign tracks to one of four outputs as well. You can also convert what u just did into a standard midi file also. One thing I didn't understand was the following phrase:

I will than go back and mute all the recorded ones and re-record the rest of the accompaniment tracks, rest of the drum kit, and whatever is remaining to the same recording medium in sequence.

I dont understand why you would go back after you've finished the song and re record the rest of the accompaniment tracks (ones you just recorded)...do you mean the rest of the other parts besides the accompinement ( such as if you want to add another piano, or strings, or trumpet) . Because when you say accompaniments first thing that comes to mind is the style itself (drums, bass, acc1, acc2 , etc).

Other than that now, the melody part and any other parts besides the accompaniments, you can not record in step mode. So you'll need to do it in real time after you've finished all the step recordings. You will have only one track of melody or whatever you choose it to be in the bsq mode. If you want more drums or more strings and more piano, you'll have to switch to the regular sequencer mode by just pressing the song record button ( no saving, no loading neccesarry). ONce there you still are in the same song but it gives you more tracks and here you can do punch in punch out and more editing functions.

I hope this helps.....my problem with the pa80 is that I can't do live editing in the bsq mode, but I like the styles so much I'm willing to use cakewalk to do all the editing. This is a pretty long answer. I hope I didnt confuse you more. If I can be of more help, please email me.
