Midi CC from cubase to controller?

I haven’t experimented with it, but you might check out Quick Controls for this. There you can configure it to send CCs, so no send is needed. I don’t know what is sent to the output, since I haven’t actually tried this but I suspect it would work. There’s a limit of 8 controls though.

Another thing you might check out is using it in Mackie mode with the Quick Controls. This, if I remember correctly will allow you to use paging to access more slots, but I don’t remember much about it. I had a BCF years and years ago, and played with this and BCF received the data back from Cubase I think… I found it overly complex to actually use, but I thought I’d mention it.
