fratveno!,
Thanks for the help. I did what you pointed out exactly and everything worked (I added ten players of woodwinds). Even after inserting the Cubase expression maps for VEPro instruments, everything was ok!
But then, after adding a next instrument in VEPro (violin) on midichannel 11 and trying to connect a new instrument in Dorico, there is no connection. Strange enough when changing a working instrument in dorico to channel 11 the VEPro instrument does react on midi. You don’t hear the audio though, while the VI on channel 11 gives VU and the track goes to the same output as the others.
It looks like you first have to set up everything in Halion before switching to VEPro to let dorico make the right midi/audio connections
Is it possible to work with several Midi Ports also? In Nuendo you can choose the Ports per track. That is not possible in Dorico I guess. More instances or Event input?
