Hi there Roland FC 300 has a nice mode (called SysEx) in which it passes all the button presses as SysEx messages (same for expression pedal etc). In this mode there's no concept of banks, patches. It basically sends out what happens to it, just like a HID device over USB. In this mode, it's also possible to control what's on screen of FC 300. If support for this was embedded into AA it would allow for full customization and integration, including tuner feedback on FC300 screen, long patch names, wah and expression pedals. This probably won't benefit AA12 users but for those who have FC 300 it would be amazing to have that in. It would turn regular AA into AA12 basically.
