After changing a fader or button, press PARAMETER to display the Parameter number you just changed.

* [51, 52, 59] multi value button, choose "INC" on the BCF

Programming the BCF2000

Unfortunately, I ran out of consequent rotary's for LFO-2, so this modulator is a bit off the logic.
The BFC2000 is not that hard to program and actually a lot of fun to do. Dump the settings to the computer after finished.
