Axis and Ohs interfaces with a Midi controller rather nicely. The developer is actively updating the application for MSFS2020 and here’s just a sample of things you can do with with a midi device. Taktility makes overlays for the X-Touch mini. Below is my WIP custom overlay that I’m designing to cover the x-touch mini.
There are still sdk improvements required to make all the things fully functional. As an example, none of the FMS buttons/knobs have a working event to trigger externally. Hopefully the next patch brings more.
There are far more things that are working that i haven’t shown. The app is simple to use once you understand how events work in the sim. I bought this on ebay for $70 which (right now) is a bargain. The app is around $10-$15 US.
So for under $100 and a little configuring on my part i have the ability to have 16 knobs with 16 knob presses as well as 32 buttons. there are two profiles on this device. on top of that, Axis and Ohs will soon release with a toggle that will allow you to expand that even further. An example of that is the altitude 1000/100 increase/decrease by pressing the knob in to activate a combination event.
