They have a free trial.
 
Don't get me wrong - I spend literally on average 12+ hours a day working with Sonar, and I champion its use - I wouldn't EVER willingly part with it.
 
For live work - Forte is a great choice, but if you wanted to mix live work with backing tracks and that sort of thing, then Sonar would be more usable.
 
I hope you find one or more ways to achieve your goals,

My first thought here was the TenCrazy MFX Channel Switch.  But I see that it's one of his MFX plugins that haven't been updated to 64-bit yet.  It may be worth a shot to contact Markleford directly.
 
Personally, I take great care with switching MIDI Channels, especially in a live setting.  Try to avoid "orphaned" controller or Note On/Note Off pairs at all costs.

The other side issue is that I run two instances of Sonar, X3 32bit for "live VST host", and X2 64bit for simultaneous "multitrack recording" of whole band during live performance. The two Sonars SHARE THE SAME AUDIO INTERFACE (Behringer X32 Rack) simultaneously.
 
I would hope I can do the same with Forte as "live VST host" and it will be happy sharing the audio interface with the "recording Sonar".

Nope - if you are using ASIO drivers, then Sonar and Forte will NOT play happily together.
 
The only way that would work is to use WDM drivers, and I believe that would be a giant train wreck.
 
Why in the world would you be trying to run two instances of Sonar at the same time?

Actually I run three instances, as Sonar X1 is used as yet another "live VST player" for the controllers I do not want to change sounds during the performance. That way I do not to keep adding those static controllers/VST's to every song in the "Sonar X3 that loads a new project for every song".
 
So far so good
The three instances can even can send output to the same channels of the audio interface and it just sums together.
 
The X32 Digital Mixer is a 32in/32out audio interface, so I am simply exploiting all the channels. And it works.
 
With one computer and one mixer (the Behringer X32 Rack with audio interface card) I get 5 major functions:
1] Front of house mix  (wireless FOH mixing on Android/Ipad)
2] Stereo IEM Monitor mixes  (performers self mix IEM on Android/Ipad)
3] Live mulitrack recorder (Sonar X2 64bit)
4] Don't need snake - (because, again, wireless FOH mixing on Android/Ipad)
5] And of course mixer's audio interface take care of the keyboard rig (hosted by Sonar X3 32bit AND Sonar X1 32bit simultaneously)
 
Yes might "bite me in the ass" someday, but I like to live dangerously! Its just a newly "revived" band:

I think the OP's issue is the controller does not respond to changing it's output channel. It just might work if you purchase the right controller. I'll look later if My Roland does this trick, I think it will.

Cantabile is another option for live performance.
