I just created a few (however, I only edited the CS6x file) which are working fine in my setup and allow bank switching. In the case of the file for the CS6x I just edited the existing file and now i'm able to access the patches from my PLG-150DX and PLG-150AN boards.
If anyone could use these i'll post the or email them, they're free (of course) but I thought it could be useful to someone else.
You WILL need to use a text editor to edit the program/patch names as the names reflect my SQ80 patches. I was able to save time by copy and pasting some common things.
I may make other files that work with other synths that I have. So far I have mindam files for:
DSI Evolver (should work fine with the Mono Keyboard too)
DSI Poly Evolver Keyboard (should work fine with the Poly Rack too)
Ensoniq SQ80
Kawai K5
Alesis Ion
Yamaha CS6x
I might later try to make ones for the Yamaha DX200, TC Helicon Voice Live, Behringer V-Verb Pro 2496 and Lexicon MX200..... I'm not sure yet... I also have a Roland VariOS with the D-50 card but i'm not sure about that either because the editor (for PPC G3/G4) for it often crashes on my MacBook Pro, rendering it somewhat useless, so I may end up selling it
but if I change my mind I may try writing a file for it too.
