I’m using cubase 5 and i assume this is the same in Cubase 6.
When you use a generic remote like Korg Kontrol, you can select one of the audio tracks, then set up one of the faders to control the ‘selected’ effects send level in your project - lovely!!! EXCEPT:
As soon as you then select a midi channel, and go into the Generic Remote page, you loose all your settings.
Cubase does not have seperate remote controls for Midi and Audio tracks, so any setups you do in the generic remote setup page for audio tracks, won’t be remembered as they don’t also apply to midi tracks.
