MidiOx will, but not sysex to NRPN.
Bome will.
BUT the BC can be programmed to output a sysex string like F0 43 10 12 27 val f7 (I assume the second last byte is the value)
eg the BC output
F0 43 10 12 27 00 F7
F0 43 10 12 27 01 F7
F0 43 10 12 27 02 F7
etc
when the encoder is turned.
It's not that hard with Mark's editor. You need to used the 'Custom Output' to enter
F0 43 10 12 27 val0.6 F7
and set up the range.
All the best
