Thank you for your helpful response ‘aptmusic9’. I also dug around on Google (funny how it does a better search of the Steinberg website than Steinberg itself :-/) and I found this forum post that shed some light as well:
So I’m guessing in the future when I make MIDI vst track I should bounce and save it on the same project at once. Then either freeze or mute the vst.
Does this save CPU resources at all? Any other tips?
