I have track templates set up for all kinds of common situations, with the most often used ones being track templates set up for different custom drum kits I put together in Native Instruments's Battery 3 drum synth. In each custom kit, each cell actually used is assigned to its own stereo output channel, and rough levels for each cell's volume are set as well. Along with that, in the Sonar track template, Battery 3 and the custom kit is loaded into the synth rack, and a track folder is created, with a whole bunch of audio tracks all inserted and assigned to pick up the output of each separate drum kit piece from Battery 3.
Further, these audio tracks are routed to separate buses, such as for toms and cymbals, etc, and those get routed to a Drums Bus, which is itself routed to the Master Bus.
So, with only a couple of mouse clicks to do the insert of one of these track templates, I get a GIANT bunch work done for me, Battery 3 loaded with a custom kit, each kit piece sending its output to separate stereo outputs, a bunch of audio tracks all set to the different audio output from Battery 3, and then bus grouping of things like cymbals and toms and such going to sub-buses, then to a common drums bus, and finally to the master bus.
The above is INSANELY powerful, and one of the things I absolutely LOVE about Sonar.
I have such track templates set up for a whole range of different kits I enjoy using, and have additional track templates set up for other synths I use, such as Kontakt, where a similar process is used for having a string section built from individual instruments, same for a brass section, etc.
So, go through the tutorials, watch some videos, consider picking up one of the Sonar books out there (they are quite good), and have a blast.
