Resolume Quick Tip: Piano mode

Use the piano switch for key and midi maps to add a punch to your visuals.

Is there a way to toggle this mode with a MIDI device? In the NUVJ software, for example, both A and B sides have a Latch button for this Piano mode behavior. The Latch setting also applies to each set of transport controls, so you can do things like pause B side for just a few moments with one long button push. It's very useful and I'd appreciate any tips on how to emulate this in Resolume.
