Midification of Yamaha CS50 & SK20

[pinksoir]

Hi.

 

I wonder if either (or both) the Yamaha CS50 or SK20 synths could be midified. I'd only be looking for note on/off. I know the CS50 has a MIDI kit already, but that's very expensive and adds a bunch of features I wouldn't necessarily want. 

 

Service manuals are here:

Thanks.
