A&H doesn’t have a suitable option currently.
However there is a “work around” that is available immediately. The third party app, Mixing Station, supports midi devices very well. It is just about plug and play to attach various motorized midi fader controllers via USB to the device running Mixing Station. It even works when you plug the midi device into phone or tablets running mixing station. There are a half dozen or so supported devices out of the box (meaning you don’t have to map/program every button of the midi device) and you can easily change the default mapping should you want to.
The Waves Fit Controller is one of those supported devices at it is very similar to your inspiration design. It’s not the cheapest option for fader controllers, but at only $1200 it’s still less expensive than the A&H IP8 which has half the faders and non of the other encoders that the Waves Fit Controller has.
