EDIT TO SAY RESOLVED _ I JUST HAD TO DO A REBOOT OF EVERYTHING CC121 is working now.
Last night I installed the trial version of SLP 11.
Since then my CC 121 has received info from CUBASE but wont send (control) anything in cubase.
I have tried this with both projects in which I used SLP11 and one were SLP was not enabled.
Not sure if this post belongs here or in the Spectral Layers thread so I hope it is ok to post in both places.
