The BC will Learn sysex if the JD-Xi will output sysex.
- check 4.3.1 page 13 of the very average manual.
Connect up the Midi so the BCR can see the data coming from the synth.
Hold the LEARN button and move the encoder you want to use. You are now in Learn mode.
Move the control on the JD-Xi through its whole range (ie go to min then to max) and the BCR should display Good.
That encode is now programmed. do the other controls and save the preset.
OR you could go to Marc's web site and download the editor as claude suggested
You can only program a few things from the front panel.
This editor allows you to program everything possible on the BCR.
Feel free to ask about anything you are having trouble with.
All the best
