baberufus: I didn't mean to hijack your thread. To your question, I'd say it's
possible to get a clean, open sound while using 350 tracks. As others have pointed out, it's not likely that all of those tracks would be playing at the same time, plus you could EQ and pan them out of each others' way. But it's
easier to get the open sound you're looking for by using fewer tracks, fewer instruments, and an arrangement that focuses the listener on what's important in the mix and leaves silence here and there as part of the performance. This, of course, is hard to do, but it's been done, and you can do it, too.
