I’ve notice that when I start working with midi the GUI becomes very sluggish & stuttery.
Working with just audio is fine, as soon as any notes midi notes are played.
This is a problem that actually began with the last MacOS update that broke cubase’s offline export.
The glitchy graphics however have persisted into version 10.
Even a simple midi arrangement with cpu friendly instruments causes the issue.
I made a video demonstrating the issue. Note the more or less smooth playback until the playback head reaches the midi sequence.
When in this condition, cubase itself becomes sluggish and unresponsive, not just the graphics.
