I agree that SysEx is beyond most people's capabilities, but it's just a arbitrary binary format using Midi as a transport. I think you can pack anything in Sysex, right? Given that your FBV protocol is likely a binary format it could be stored in Sysex. I agree that the speed of midi might pose a problem especially when sending large patches (with like IR's). The benefits may be too little to spend any time implementing Sysex, but I think it's possible, or am I off base? Of course, in order to allow users to use the Sysex, the formats would have to be published. Again that's a lot of work and may open Line 6 to exposing proprietary information. Note: I've done some limited parsing of Sysex for a side project that never got going.
