1. I created an "audio" track. 2. Next, I created busses containing my main FX plugins. 3. On the AUDIO track, I put "inserts" for each of these FX busses. 4. Save the audio track as a "template" track.
When insert this newly created "track template," in any project, it inserts the track and the busses. The only thing is, the BUSSES have the green SOLO icon selected.
