Hi fastlanestoner,
you can use
1) Render function on the track, or
2) Apply FX on items, or
3) "record" (old-school) on another spare track.
To record track 1-"Synth" (which has MIDI clips and VSTi synthesizer) to blank track 2-"Recorded-Printed Synth":
- create send from track 1 to track 2
- on track 2 set recording options to Record: Output (stereo), Input: None
- record arm track 2
- set cursor on timeline to where you want to start play/record as audio
- start Record button, wait while required section is over, then hit Stop
- track 2 now has audio item with synth part recorded from track 1
Happy midireaping
