Matt,
There is an incomplete INS file for Cakewalk published on the L'il Chips site at this URL:
http://www.lilchips.com/cakewalk/ins/xv.asp It is only a preliminary version, and seems only to be correct for the USER bank, and for Preset Banks A, B, C, and D. Other preset banks are not correct. But it is a start!
