I just stumbled upon this very cool controller:
It’s not really small, it’s not very cheap, but it has also been developed for (live) musicians (not only optmized for DAW use).
It has 8 motorized 100mm faders, 16 buttons, 8 knobs and 8 scribble strip displays.
After all, it’s quite compact though, compared to similar controllers (300W x 260D x 52H mm)
The price is around 1150€.
You can read the full discussion about its development in a very long forum thread here:
