@GarfieldModular -- thanks for the kind words!

@Lugia -- interesting point, very oblique. In a previous incarnation I did all my music in the computer, which meant lots of editing and rearranging to try to keep the piece in motion. What's obvious to me, but maybe not to others, is that in this piece there are a lot of static parts, a lot of thinking-while-recording, which if I was working on a multitrack recording I would edit down. The modular is an escape from all that clicking, but I'm not yet proficient enough on the instrument to achieve the musical results I want. Whether I adopt your idea or not, I am sure that "keep practicing" is part of the answer :)
