[sdiy] Polyphonic MIDI to CV

Here is a MIDI to matrix keyboard interface I built
in the 90’s  for my Korg Poly61.
It didn't have any MIDI IN connector.. 
Now it does and still works well. 

The MIDI interface is 61 notes polyphonic and the idea
could be used in your project..

Just a circuit suggestion..

Hi, I'm thinking of creating a string machine starting from a project from

the 70s. Basically, a replica of an analog string machine with new

components. The tricky part I think is the full polyphony with the MIDI to

CV conversion. There will be no keyboard in the instrument but there will

be midi input connection.

 

Do you have any idea, project that does not use commercial modules that

would be impossible to implement in the circuit?

 

Thank you

Francesco
