I'm using super-large templates, and this is what I do.
I create a track exactly as I want it - FX, samples, whatever. Then I have a custom action that does this:
Code:
Track: Mute tracks
Track: Set all FX offline for selected tracks
Track: Lock track controls
This removes all CPU load, and the "lock" action dims the track so it's obvious it's not active.
I can then search for any track in the Track Manager (eg "Vln I SHORTS") and with a button click I have another custom action that enables it.
Is there any reason this kind of thing isn't viable? I did the same thing in Cubase, except I used its native track enable/disable functionality.
