I wanted to be able to use my Casio XW-G1 in Cakewalk as well as my XW-P1, so I built a Cakewalk Sonar Instrument Definition File based on the one Mike Martin did for the XW-P1. You can download it here. Casio XW-G1 INS.zip I tested it with a 4-track MIDI file setting two tracks to synths, and two tracks to drums, and it seems to work well. Please let me know if you have any problems with it. -Sheldon Sims-
