That PCR M80 just might send the corresponding MIDI patch data when you use its patch selection buttons.

Therefore, when hooked directly to the SD2, via software loop or directly, you may well be able to select at least the GM bank from the keyboard's controls. Well worth trying.

A faster method than using software looper is to simply disconnect the USB connects at the MIDI cable end and use one MIDI cable to go directly from keyboard MIDI out to Ketron MIDI in.

Ralband and Powertracks use a different Patch Map format than Biab. Both files are published on this website in the Patch Map area and both should be downloaded if you want to use your SD2 with both programs. Read up on it, they are two different format files that install differently in each proggie. Both are thoroughly tested and work with each program, though.

In RB you must rename the existing file and then drop the new one into the folder with RB shut down, then start RB up again.
