CatSynth Pic: Gracie and Korg Poly 61

Gracie is back, this time with a Korg Poly 61 synthesizer. From Alsún Ní Chasaide (Alison Cassidy) of Synthetic Dreamscapes, who repaired the instrument.

This unusual Korg Poly-61 with factory MIDI retrofit (not Poly-61m) is finally finished and working perfectly. As usual, the last 20% takes 50% of the time!


In this case, the non-working panel buttons were traced to severe oxidation around two connectors on the MIDI board. Both pin headers *and* connectors had to be completely replaced / rebuilt for this to be long-term reliable. Also, one new rubber key contact set was needed, and Andrej’s new CPU board from yesterday.


And after a tune-up – perfect!! Ready to go back to its local owner 👍🏼😊

Gracie is the Quality Engineer for these repair projects 😸🎹
