I use Sonar with playlists as my fall back for providing backing tracks for my live solo act. I've never had to use it 'for real' yet. I have a Roland Sonic Cell for that and I use it only for MIDI files no audio.
I have however under the above limitations rehearsed with it on several occasions and never let me down yet.
Sonar 8.3.1 PE on a Toshiba Satellite T6400 @ 2.00 Ghz, 3 GB RAM with Windows 7 x32. If that's of any use. The only thing I couldn't get working was the Start/Stop via MIDI for some reason.
I thought this was the whole idea behind Sonic Cell - create your stuff using Sonic Cell as your interface and sound module with Sonar, create a playlist with SC play list editor, dump everything onto a jump drive and let SC do the play back on the gig...
Unfortunately, there are only stereo outs on the SC, and I'm not sure you could have it play back MIDI and audio in the same song. It would be nice if it had at least 4 outputs and a click track output.
The other thing is that with Sonar 8.5.2, you'd be able to use MIDI to control the Matrix View, to allow for some variation when playing live.
I've heard that the Fantom G and Sonar play well together. It's my understanding that the Fantom G could be used as a audio and MIDI interface to Sonar. When your stuff is done, you could dump it from Sonar into the Fantom G sequencer, and with MIDI controlled RPS, you'd have some live flexibility.
The only problem is that the Fantom G isn't a cheap solution - however, I would trust it more in a live situation than a computer running Sonar.
