I am having to uninstall Cubase 7, due to big problems -- so until the planned fixes come out, I would stay away from it.
I read about the issue with the Steinberg HW (UR824), but the issues I am having are not the ones described.
I get spikes on track 1 when not hooked up to anything, every 15 secs or so.
Worse still, the performance meter is spiking constantly, with "nothing going on at all" -- meaning no playback or recording happening. With straight instruments only being recorded, these spikes result in dropouts and "hiccups". No inserts, sends, automation being used.
Their forums show some issues, but nothing this drastically wrong. Anyone else noticing this or similar?
