I need to record several VST tracks into one audio track to diminish the load on the CPU. I can’t seem to find out how in the manual. I used to do it but now it is not happening. If you can diect me to what section in the manual explains this, I’ll be happy.
Solo the tracks you wish to combine and do an audio mixdown export of the main Stereo Out with “Import into Project - Audio Track” selected.
You could also try to “Freeze” the tracks causing a high load. Or just export/import to audio one track at a time.
Since you don’t mention which version of Cubase you are using it’s rather difficult to point out a section of the manual. Look for something relating to Export Audio Mixdown.
