Hello,
There are several topics in this forum section which clearly indicate PB Connect won't transmit Midi CC messages when inserted as a VST instrument in Cubase (12 for me). I first realised it when trying to use the sustain pedal on a sampled piano, Polybrute being used as my master keyboard. Cubase's Midi input monitor displays no activity when the pedal is depressed.
As soon as PB Connect is unloaded from Cubase, Midi CCs are transmitted normally whatever the selected Midi track.
I sent a support ticket some time ago but I in the end I had been answered it is PB Connect's normal behaviour...
We clearly need a fix and be able to use the Polybrute with PB Connect at its full potential. It makes nonsense to have to cope with such a limitation on this incredibly powerful and fantastic machine !
