I recently returned from a couple of EU & UK festivals, running Bitwig as my DAW and Chameleon as my only controller.
I've just up/downgraded from the sizeable 22inch touch screen to a much more manageable and travel-friendly 16inch touch screen for Chameleon to run on. It's not as sensitive as the larger 22inch which occasionally means button aren't triggered when hit, but it is much nicer to travel with something that small and only requiring one cable instead of 3.
Here's a clip from the trip, with the occasional glimpse of Chameleon.
