To make it easy to use with a controller/touchpad it sounds like an instance per track is the way to go (that way the control could always be the 1st one of the selected track for instance). BUT, that's why
@Simon Ravn comment surprised me as I always thought that it would not be the way to go CPU wise since your cores are now spread accross so many different instances.
Going with Folders or Channels disabling within an active Instance will probably accelerate the CPR loading time, and might be more efficient CPU wise since all the core are spread accross a limited amount of instances.
So for those who use Cubase and VEP together with large template, what would you recommend?
