jloeb and Chris, thanks for listening and thanks especially for taking the time to post your reaction. I really appreciate it. It's no fun to toil in a vacuum.
Chris-- I always do a lot of tweaking. This piece was no exception-- mostly keyswitched patch changes + midi controller #11. But once I had worked out the first violin part I was able to transfer much of the tweaking to the other sections rather quickly since this piece is largely homophonic.
