Just know that Track Templates don't save any audio or midi clips of recorded data. It's not their purpose.
But, I too use track templates all the time, specially for drum kits, as I will have each kit piece from a drum synth routed to its own audio outputs from the drum synth, and routed to its own audio track within my drums track folder. I also have a bus created for parallel compression, toms, cymbals, kick, and snare, to give me excellent control over things quickly. ALL of that stuff is also save in the track templates, and it save me COUNTLESS hours of time in any given month, rather than having to set it all up for every new project.
WAHOO!
