OK, I also have Cubase 11
Please forget my previous message - the PB does not
send program change messages. Sorry about that confusion.
You will have to insert program changes manually in your MIDI parts.
You can also select the program in the Cubase Track Inspector, but not the bank. That's because Cubase uses the Bank Select LSB message (CC 32), while the PolyBrute uses the Bank Select MSB message (CC 0).
To insert a Bank Select MSB message in the controller lanes, you must first add Bank Select MSB to the list of available controllers:
* Click the down arrow on the bottom of the controller lanes view,
* Select "Set up Available Controller..." to open the available controllers dialogue
* Scroll to "CC 00 (BankSel MSB)" in the available controllers dialogue
* Click "Add" in the bottom of the available controllers dialogue
Now you can select "CC 0 (BankSel MSB)" when you add a controller lane.
Also add a Program Change lane.
With that done you can insert bank and program messages as needed in the controller lanes.
Yes, it's a bit convoluted, but hopefully you'll get it working.
