Glad to hear you got it working!!
Like Janus mentioned, you’ll need to drag each instance to the rack view, but don’t forget to set each VST instrument a different midi channel like in my screenshot above!
As for playback templates I’ve yet do try them, I just do everything manually.
I usually just add a VST Instrument in a K7 instance in play mode, and then add it to the selected instrument along with the expression map. My pieces are fairly small at the moment so it’s not a lot of work.
