hi Steve
thanks for the response.
indeed, i could knock together an NRPN converter on an Arduino (or WebMIDI, Swing, etc) in the blink of an eye, but i like the single-box approach. also i get the feeling that with a few additions to the current firmware hack, writing a native version wouldn't take very long at all.
maybe i'll do the converter while i investigate the native solution...
and btw, on UART zero, if you stick a switch in there that disconnects the MIDI optocoupler (it puts 5v on the line) you can use that one too. regular Ards only have one hardware UART and the switch is necessary in that case.
best regards
Jason

Hi Jason.
The arm chip itself can handle the sigend type we need. I gave up lobbying Behringer and instead put a Arduino Mega as a man in the middle to do all the transforms. Mega wad necessary because it has 4 UARTs - use 1 2 3 not 0 as this can interfere with the flashing process.
This allowed me to midi merge from an 88 keyboard and in my case AKAI Miniak, to read in BCR data and send updates round the loop so that BCR and Miniak were in sync.
If you didn't care about that then perhaps 2 cheap Arduinos looking for NRPNs and transforming the over/underflow could do the trick
Lot easier than hacking a firmware (for me at least).
