Hey Gampopa. If you use Cakewalk, be sure to stay in touch with me. I am 99% done with a really really cook Studioware Panel for controlling the EA-1. It has all the knobs on there - with PART A and PART B on screen simultaneously, without switching between the two. So it's sort of an improvement over the real thing!
Included in my final ZIP file for that will be a .INS for Cakewalk that lets you easily access banks C and D. (A and B are easy to get to, no .INS required.)
Stay tuned. I'll post here when the Studioware is ready.
