Hello!
 
I wonder if anybody could guide me to the best approach to play live keys with CbB?
I would like to create patches and change them on the fly, something like MainStage.
 
Thank you!!

Are you talking about having a project in Cakewalk by Bandlab and then running MainStage separately? 
 
By the way MainStage is an Apple product and I don't think it will run on Windows. 

Thank you for you reply, karhide. But what I actually wanted is to use only Cakewalk (and its vsti) to play live, changing patches in a fashion like how MainStage works. I am used to Sonar/Cakewalk, but I am now playing in a band. 

Your taking about using a DAW as a VST host. Any DAW can be used this way but it's a bit clunky. It's not what DAW's are optimized for.  There is software specifically made for VST hosting that the Pro's use for live performance. 
Off the top of my head I do believe Reason,  Ableton.  Cantabile is a popular one I think.

Maybe take a look at Akai VIP software.  They have playlists that can load multis that you create with up to eight VST instruments in your collection.  Run it as standalone, or as a plugin in your favorite DAW. https://youtu.be/RsG-89JoA-Q
 
VIP standard is currently on sale for $49.  https://www.pluginboutiqu...-AKAI-VIP-3-1-Standard

Excellent, thank you very much for your help!!
