Bc2000 (for the BCF2000 & BCR2000)

success!!!

I first pursued the option to control the sound module's individual drum sounds via nrpn messages to provide the filtering I wanted, since my preference is to not have a pc in the MIDI chain - and it worked!

a lot of ducks needed to be in a row here is a run-down:

the sc-88 pro manual did show what nrpn messages were required to change drum sound levels regardless of the note messages received - in this case 1a in hex, along with the drum sound number, eg. 24 in hex to control bass drum 1.

then it was a matter of setting up the bc to send this along with volume levels for toggle on and off. the bc parameter 1 is nrpn and I found the bc parameter 3 setting through trial and error with midiox was 3364 in this case to send the above hex values. to alter the levels of other drum sounds parameter 3 is changed. parameter 4 and 5 send the toggle values, ie. full volume and mute.

then the sc-88 pro just needed to have receive nrpn messages turned on for the MIDI drum channel 10.

next I will see if the akai z4 has similar abilities, and the manual suggests it is even easier on the z4 since you apparently can specify your own cc messages to control modulation. hopefully I can get the z4 to respond in the same way as the sc-88 and use the same bc presets.

I'm constantly impressed by the MIDI standard and how so many different devices implement it well to allow such flexibility and functionality.

thanks for all your help guys I learnt a lot.
