I have a strange thing that happens to me sometimes with Cubase where I’m working away and have no problems at all with MIDI input latency, but then all of a sudden I notice that when I play my midi keyboard connected into Cubase running a VST instrument, I have a very noticeable MIDI latency which makes it un-playable.
Since it doesn’t start off that way, I have thought that maybe it’s because I have too much going on in my project, but if I go and disable various things, or even remove tracks altogether, I can never get it back to having (essentially) no MIDI latency.
It only effects when I play my keyboard… the VST’s run just fine within the DAW from MIDI data in the track. If I start a new project, even without restarting Cubase, I don’t have this problem. I’ve tried restarting Cubase, my computer, my MIDI controller and nothing helps. It’s like something happened (some obscure setting?) automatically and I can’t undo it.
I’m using Cubase 7.5.20 | Roland A-800 | Windows 7 | Connected via USB
