I have one, I'm slowly getting into using it (53y old).
At the moment, the Morningstar MC6 is the heart of the midi-set up of my band (https://vi.be/platform/bandwerk) but the plan is to change to Mortrix. As we control our drums (Beatbuddy), keys, effects and loops via midi, it is a slow process. At first I thought the different operating choices of the Mortrix would make it difficult to change from the MC6 (which is doing a good job at controlling everything) but now I slowly start to see the benefits of Mortrix. A lot more testing and thinking is needed but I am confident I will get there.
I am keeping an eye on this page and the Mortrix discord page.
