I don’t receive CC data from my Polybrute, after a long frustrating troubleshooting maneuver, I installed Cubase 12, and found that everything worked as expected in ver. 12 What’s wrong in ver. 13?
Hi,
Do you use All MIDI Inputs or a dedicated In? Can you record the MIDI Notes?
Could you double-check the Preferences > MIDI > MIDI Filters? By default only the SysEx is enabled for both the Thru and Record.
Thanks for taking the time to reply, I should have deleted my post. It’s Cubase 13’s new way of handling CC data that confused me, along with Arturia’s dedicated driver for data transfers. There is a “hidden” VST driver for PolyBrute’s software. I think it’s that and the new features in the Cub that teased me. There is a hole through now, although I am still on slightly uncertain ground. 
Hi,
By default Cubase 13 set the type to Ramp for the most MIDI CCs. Previously it was Jump.
