Kicksville's live show is completely built around Sonar. I can go into more details if you want, but basically, all the technical elements you see in this video are driven by Sonar: lights, video, MTC feeds, patch changes for the remote computers (we have 8 onstage), and console automation. The mix you hear is actually the 2-track mix we send to FOH, recorded directly back into Sonar during the show, with no post-processing beyond a limiter to bring the levels up for the video.
https://youtu.be/omElhthKQIQ A lot of folks do this, but we've taken it far beyond most.... 70 inputs, 10 stereo monitor mixes, extensive dynamic automation (meaning we don't just change scenes on the console - we're directly controlling things like FX sends, channel EQ, etc.), and a lot more.
Some things to keep in mind as you try and implement this kind of thing into your show:
- We have everything laid out in one large Sonar project, so there's no loading files during the show. Some folks use the playlist feature or call up separate files for each song, but for us, one file was a better solution considering lighting changes and video cues happen between songs.
- Don't stress the main computer. The less load you put on a machine, the less likely it is to crash. We have separate machines for each person's rig, running softsynths, VST effects, etc., so the master machine doesn't have to do the heavy lifting.
- Test, test, test, and test again.
- Take the time to carefully prep any playback tracks. Match RMS levels from song to song, and make sure things aren't going to surprise you at the gig. For example, that 808 bass drum that sounds awesome at home may have so much 40Hz that when you play it back on a full PA, you rattle the trusses out of the grid ;-)
- Did I mention testing?
I'd be happy to go into more detail about the technical details if you'd like, but it's pretty complicated and involves lots of eye-wateringly dense Excel spreadsheets

I can say this though: in 7 years of doing this show, we've never had a single problem with Sonar. Not once. So, there you have it.
cheers!
