a question exc btn

Do you realize that you can fill each touch screen with 84 executors?

You can turn a section of the screen into an "executor" page or window and use it as virtual masters.

And now, with Midi notes added, you can use various Midi push button pieces. My favorite being the JazzMutant Lemur.

It's expensive but you can do a TON with it.
