I almost forgot about it… my Korg MS20
The poor machine and has been sitting in the attick of my parents for years.
If I recall well one of the oscilators is broken. Given that this is a electronic instrument that should be easy to fix with a soldering iron, a transistor, condensor, resistor, and/or some knowledge of electronics.
With the latter I am less comfortable. Fortunatelly the Internet provided me with a copy of the Service Manual and the repair job can be done by handy friends.
I remember fabricating a “drum-pad” by covering two layers of duplex wood with aluminium foil and seperating them a tiny bit so that hitting them with a drum stick would control the input. That with the white noise generator would produce that funky “clap” noise.
I should undust the machine and compare how it compares with Korg’s Legacy Cell software.
Further googling made me aware that this little machine has quite some cult status. It has been valued at about $1000. I am not sure if I want to sell this memorabilia of my teenage years.
