I have a control surface built into my mixing desk that sends MMC data to Cubase for the basic transport functions (play, stop, record, etc.) and Cubase, up to version 6.5, used to respond with MMC RESPONSE messages so that the “Recording” light of my studio could light on when I hit record on my desk.
Since version 7 this MMC stuff works intermittently, sometimes stops working for no apparent reason, then works again as soon as I control the trasport via keyboard shortcuts, but soon after stops working again.
Also trasport commands from the Generic Control Surface stop working along with MMC. My controller sends a few MIDI events to trigger some of the most used functions such as arm, mute, solo, volume, pan, etc. and when MMC stops working, the control surface stops working as well.
Nothing changed in my hardware since when I used Cubase Studio 4, Cubase 5.x and Cubase 6.x, same control surface, same MIDI interface, same computer. Just the Cubase version grew up, and I started experiencing issues from Cubase 7.0. And this is a major issue for me.
Any advice on this matter?
