Bc2000 (for the BCF2000 & BCR2000)

and we come full circle to the benefits of putting a small embedded processor between the MIDI IN/OUT of the BCR ... the -ve NRPN thing.

It frustrates me slightly that the BCR uses an ARM chip that has signed and unsigned integers. For the want of allowing the signed to be considered unsigned we could have both the official NRPN (that Behrninger supports) and the unofficial one that AKAI, E-MU and a plethora of other people support.

Hence the Arduino Mega, and LCD and hours of design/experimentation in the garage ... cannot be bothered to watch the Wimbledon final ... hmmh time to play with this global parameter and my bespoke buffering algorithms.

I decided I would stick with the sysex because of the obvious advantages (eg doesn't matter how many different synths receive the sysex - only the intended one will respond).

On the BCR, I have to press a switch 7 times or rotate a knob, which shows number 1-7 on the display - and maybe see if I can fit a label with the 7 items on a paper overlay...
