Re: BCR2000->NRPN->Prophet 12 Problem

2016-01-07 by wytchcrypt@...

Just hooked the BCR2000 back up to Midi-Ox and found something interesting. Setup a rotary encoder to toggle LFO2 Wave Reset and a button to do the same and compared the midi messages. The rotary successfully turns the parameter on/off where the button only turns it on. The midi sent from the rotary & button are different...problem being the button doesn't send all 4 midi messages required for the NRPN, leaving off the final LSB value required to turn the parameter back off.

Seems very odd...the button is set to send NRPN but doesn't send the full 4 messages???

Unfortunately, I don't think there's anything I can do to fix this, is there???
