Awesome idea and functionality, however not perfect at the moment (Dec 2019). USB connectivity can drop at certain situations, sync isn't rock solid, lights on module bleed heavily into surrounding buttons so sometimes not clear to see the activity - however, very promising that this will be improved and then this is easily a 5 star module - highly configurable, deep features and ability to use USB and MIDI DIN at the same time.
Go for it if you are daring, since it is already highly useable, but be warned.
*update
With bugs fixed and a great configurator tool released, this is a stellar module! Timing is tight, it is easy to switch and create profiles, cv response is tight, timing is great. Additional features like AUX A and B for clocking and MIDI transport are well warranted
