I’ve got a project with no Audio Tracks and 9 Instrument Tracks (one VSTi each) along with a Reverence FX channel and a couple of group channels. Overall pretty modest size. Then I opened the Score Editor in non-page mode for a single track to read lyrics during playback. Suddenly I’m getting all sorts of audio artifacts. So I open the VST Performance meter and sure enough the peak meter is jumping around in the 80-100% range. If I close the Score Editor (or even minimize it, it turns out) everything goes back to normal and the VST peak meter is somewhere under 5%. If I make the Score window visible again performance goes in the tank, minimize it and everything is OK.
Anybody got an idea of what’s going on? Granted displaying the score is going to use some additional resources, but my graphics card should be handling the bulk of that. I’ve tried switching ASIO guard off and also setting it to high but that had minimal if any effect.
