[russian32gb]

Good morning guys from Greece Peloponnese island Aigio town , I have a project in mind and would like help with it , if someone is electronic devices repair technician or expert . I want to make a modified custom minimalistic slim midi keyboard from that M audio prokeys sono 61 digital piano midi keyboard hybrid. I want to decase it cut the unnecessary and bulky plastic and keep only the keyboard and the main board pcb on the left under the pitch bend modulation joystick and the keyboard base assembly. I figured out how to do it all but , I need to find a way to get the USB b port out of the shell ( that is on the secondary PCB board of audio input and outputs that is connected with the main board ) . Now I have spare USB b female port to do it but , I need to know which inputs are the + - ground and signal wires that are on the main board that's connected with the secondary PCB board so I can get rid of that secondary audio input and output PCB board and keep that USB b female port option on the main board. Thanks in advance

Normally, it's possible to find and download a copy of the service manual from one of the usual sites but I can't find anything listed for your model, only user manuals. However, I did find the service manual for another model, the M-Audio Keystation_49es_Mk3 and it shows the pinout information for the USB socket.

The USB socket is pretty much a universal standard so although the models are different, the connections should be the same. If you need the full service model, you can download it here

I hope this helps.
