Bc2000 (for the BCF2000 & BCR2000)

Hi,
Does anyone know the correct parameter update request (or if one even exists) to cause Live (v7) to send all it's mapped CCs?

I'm attempting to get BCR knobs shared across 2 banks to synchronise (ie, encoders 1-8 are always mixer channel 1-8 levels, while the rest of encodes switch between fx sends on bank 1 and fx parameters on bank 2).

I figure that if Live can successfully respond to an update request by sending its mapped CCs, encodes 1-8 will always be in sync between banks.

Thanks in advance,
Skye
