"Re"-midification of Yamaha DX7S keybed

To answer the question you'll need to know how the switch matrix is configured in the DX7 (I'd assume circuit diagrams are available on the net though).

You'll also need a core and a DIO matrix to make it happen. The pitchbend and mod wheel may require an op amp circuit to shift and scale the right voltage range for the ADC on the core.

 

I bought an original DX7 20 years ago that was about 12 years old at the time.

For the last 15 years I've used it as a master keyboard midi controller. I have a sheet of plywood over it with a cut-out for the keyboard keys, pitchbend and mod wheel. This provides a surface for computer keyboard and mouse/trackball as well as other control surfaces. It actually looks surprisingly good and highly functional as a music workstation.

 

I'm using it daily at the moment, and it's done a lot of work over the years. The build quality of yamaha is amazing!
