Hello,
 
I'm using Sonar Platinum for live performances and I would like to switch between different VST instruments on the fly. A simple way is to change track focus with a mouse, but I believe there should be a way to do it remotely with a midi keyboard. Changing midi channel on a keyboard doesn't help because i need to do it really quickly, i need some kind of shortcut when a button on a keyboard immediately makes a track / plugin active. Could anyone help me with a solution?
 
Thanks,
Nick.

To avoid bad experience on stage, I recommend triple test that it works as expected and do not change plug-in version till you have a reason. Also I would recommend to use separate device (or separate MIDI device as seen by Windows, in case your board support it).
 
With that plug-in, you can create any possible direct mapping: focus particular track, open/close GUI for particular VST (Synth or FX) and map knobs/encoders to particular parameter (the result is close to MIDI learn). But be prepared to invest some time to learn how to configure all that.

Thank you, this is exactly what i need!
