The SK is working, but there is some weird stuff happening. I've been holding on to it in the hopes I would find another one with issues so I can merge them together, but this hasn't happened yet so I hope it can become someone else's project.

The main issue is that every 8th note you play, has a bit of a filter sweep to it. It depends on the sound how annoying this is, with some it's hardly noticable. It's also not always there but I haven't found out what makes it happen, it seems very random. Also the asdr part of the synthesizer area is not working properly. The other buttons in that part work and also every other part of the unit seems to work as it should.

A friend of mine had a look at it and thinks it is the main chip that is causing the filter sweep. Apparently this unit has two of those, so if you can find another working chip in a broken SK, that could very well be the fix it needs.

It is in good cosmetic condition, only at one side there's a bit of the fake wood cover that has come loose (see pic).

It comes with the flightcase but it's super heavy so shipping it far away is gonna be expensive. If you happen to live close, let me know if you want to pick it up.

Let me know if you have specific questions about the issues if it isn't clear from my earlier description.

I'm also open to bids!
