Thanks for the extra info Jason! I was working on a sort of memory map for all the patch info, but I'll go back to working on the NRPN input.
You know, there as a glitch I noticed while working with the BeatStep. If I adjusted Cutoff for example, then tried to adjust Res, the Cutoff value would change right before the Res would. I figured it just needed a null RPN between the adjustments.
