Speaking of Sound Diver, I have a problem controlling the JV1010 in it as well. It will allow me to edit programs and use the microkorg as a MIDI controller to play parts as I tweak all the parameters, and it lets me save to the user banks. Only thing is, if I go to load a setting from one of the Preset (patch) banks, it fails. I can provide screens of the exact messages if needed.
I know this is off topic from Cubase, but some people from this forum have responded who directly have used a JV1010 in Cubase before so I figure it’s not a far cry as JV1010 owners to know how to tweak parameters with the program that came with the 1010.
