Not everyones solution, but the D8B with probox got 24 + 1 motorized faders, pan, meters, transport and so on, using the standard MCU and combining with generic remote settings its quite capable. On the con side - its an old machine, can be noisy if you dont install new power supply. This is the perfect solution for me. I wanted faders and pan knots and this works pretty good.
