As the keyboard of my Poly61 had lots of defective keys I needed a
MIDI-interface.
As all the solutions to buy were too expensive I decided to design my own.
It is a universal Midi-interface that sits in parallel with the keyboard and
simulates keypresses by 
means of analog matrix circuits.

Compared with other midi interfaces for some other similar synths that generate
the keypatterns 
direct it is more expensive but easy to adapt to other synths with matrix
keyboards up to 64 keys.
Only a software update is needed.
