Bc2000 (for the BCF2000 & BCR2000)

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).
