Thanks, Biker Dude. So, I watched the video which is great, but I am still a bit unclear on a few points. Maybe I should work with it a bit before asking questions, but here are my confusion points.
1-The part about importing a file v creating an instrument was not clear to me. Wouldn't you need to do both?
2-Rather than adding patches one by one in Sonar (127x8 for the JV), would it make more sense to take an existing ins file and edit it in notepad to create the new file?
3-I have never been clear whether the synths I have are "Normal," "Controller 0," or "Controller 32." The ones I need to do are Roland JV-1080, Kurzweil PC2R (same as PC2 but rack-mount), and Yamaha Tyros 2.
4-Let's say I found a file that appears to be correct for the four factory banks in the Roland JV-1080, how would I know how to label the new sections of the file? It looks like the existing file has headers like PR-A, PR-B, etc. I could guess that the new sections need EXP-A, EXP-B or something, but I might try a lot of things before I got it right. Same questions on the PC2R (although it uses different nomenclature)?
Of course if someone had a file with all the expansion cards and knew the header format, I could swap them around to match the slots where I have installed my cards.
Sorry to be an idiot, but this is quite frustrating.
