I tried to use it with Sonar X3 and Sibelius and sync was far too unreliable to use.  With Notion it was reliable as far as sync but passing MIDI data from Sibelius to Sonar was unreliable.  Even if I got it to work, Sibelius and Notion don't implement re-wire in a way that would be useful to me.  If you could load all of your sounds into your DAW and just run a re-wired notation app to send MIDI data and control the VSTi's in the DAW it would be usable to me.

i could never get Sonar to Rewire with Notion, which is a shame as i find notation much easier to use than piano roll/midi editing for orchestration. Notion is a great product in its own right though.

use it with sibelius and reason... haven't had any unusual sync issues with either except for repeated passages in sibelius.

So, I can export my Sonar files into Notion, and they will become a score there? That's what I'm talking about. I know XML files can be exported/imported, but usually people are doing that to go from one DAW to another. I'm talking about going from a DAW project in Sonar, to a notation project in Notion or some other program.

Rewire is a real time process. It allows you to pass midi data to a client which then returns audio to the host.

It doesn't work well for notation in this case because Sonar has to be the Host. Now if Notion could be the host you could write your midi score in Notion Rewire to sonar as Midi and return the audio in Notion. Sadly it doesn't may works as the former not the latter.

You can export XML from Sonar and import it into Notion, but for the editing effort required its easier to just do the project in Notion if a good quality score is what's required. Notion hosts VSTis but if the sound isn't good enough that's when to export the MIDI XML and then open that in Sonar and then finish the audio side if you also want a master able finished audio project. A bit convoluted but the only way I've been able to get it done well.

I have just begun using Sonar Professional after using Reason exclusively for years.
It's a great program. I'd even say it can be quite a teacher when it comes to synthesis, signal paths, and creative mixing techniques. The version i have doesn't have any vst capability(6.5.2), but i love it, so i kept it.  
Prior to this setup, i was running Reason in tandem with Komplete 8, Maschine, and u-he's gorgeous VST's within Logic (before the upgrade/downgrade debacle took place).
Anyway, the need for more diverse eq's and signal proccesors overall is what leads me here. 
but my inital question to the salesperson was, "Does it have reWire?"
Resounding yes=sonar professional!
diving into rewire TODAY.

Reason complements SONAR very well, given that Reason provides a rack of useful instruments. FWIW when Cakewalk implemented ReWire the guys from Propellerheads said it was one of the best implementations, if not the best implementation, they'd seen of ReWire.

Can't wait to really see it in action.
I think i got a little overambitious in trying to rewire a fully loaded reason song file (16 GB of RAM can get your head in the clouds real quick). then i realized that i was trying to reinvent the doggone wheel, and just bounced out the tracks and made the song sound 280% better. That's some true percentage.
 
Checked out your guide and that was the only way i even attempted half of it, so grateful for you writing that.
for anyone else searching or trying to figure it all out,
Start from the beginning of the guide to play ReWire and Sonar.
