I will built everything on top of MPD24.
I think it will be easy, just wanted to be sure about encoders because MPD24 firmware only accept absolute values from encoders and they are useless, so no relative or incremental data from them. they are sending values from 6 o'clock to 18 o'clock, so 180degresse(and when I pass that 180 in any direction they are not sending anything in any direction, below 0 or above 127, but you can spin them as long as you wish)and I hope that there is some absolute encoder that will imitate EQ POTs from mixers.
I dont need PADS so I will be replacing it with buttons, and MMC buttons on bottom can send MIDI too so I will have 16+5 buttons.
Basically I just want to rearrange it and do something about those useless encoders(but now I see I only can move them :(
