Show HN: Impetus – I turned my MPE keyboard into a DAW control surface

Hi HN,I'm a sound editor and composer. I had an MPE (MIDI Polyphonic Expression) keyboard sitting on the desk in front of me and not enough space for a DAW control surface. The MPE keys to me were about the same size as a mixing board fader, and operated on the same y-axis gesture, so I decided to see if I could make the translation.About a year later, I have an 8-channel control surface running on HUI or Mackie Control with all major functions, including a system wide keyboard shortcut and macro engine.The crucial part was getting the keys to respond like a real fader, starting in the right position when touched and not introducing jumps or jitters into the mix. The result is really smooth control though and it works better than I imagined it would.It's macOS only for now, and works with ROLI Seaboard models and KMI K-board Pro. It should also work with Haken Continuum, but is not tested.DAWs tested and confirmed: Pro Tools, Logic Pro, Cubase, Studio One, Reaper, Ableton Live and Digital Performer, plus video editors using the same protocols, such as DaVinci Resolve's Fairlight page.I would love any feedback, especially if you own any of these devices and can try it out.
