Hi
i recently developed an alternative, custom firmware for the MIDI Captain series of controllers which can communicate in a bidirectional way, similar to the Fractal MIDI specification. It has at first been developed to control Kemper Profilers and has a pretty broad user base there already, but is basically designed to support multiple clients devices.
I would love to add Fractal support, but don't have a Fractal device myself, so i would need people who can help by testing the firmware dev versions for me during the development process.
You can check out the project online: There is a web based Emulator which is used to configure the MC, but also emulates the PySwitch project in the browser, so just have a look to get a first impression: (sorry i am not allowed to post links, so replace the dots please) pyswitch(dot)tunetown(dot)de
The project is hosted on Github: github(dot)com/Tunetown/PySwitch
In the Kemper forum, there is a massive thread about it, it is linked in the README on Github.
If there is interest and i have some people for testing, i would give it a shot. Please post here if you can support this
