“Collection in person only, from West or Central London. No delivery/courier.
All keys work and move smoothly
The synth is in tune
All presets sound except two of the breath controller presets (sax/harmonica) – I have no breath controller to test
Pitch bend and mod wheels move smoothly
Comes with third-party PSU and small-format printed manual from the internet

However, while trying to replicate the sound synthesis example in the instruction manual, I could only get so far before I couldn’t get the intended response. Not sure if it’s just me or the synth, so I am listing as spares or repair on the off chance there might be something wrong with it.”

“Yamaha DX100 (Working). I plugged it into my amp and tried a bunch of the cool sounds. A few keys are sticking but work if hit hard. I don’t understand midi or more complicated functions that’s why I am selling it below market value in case it needs some refurbishing but it does work. Sold as is with a carry bag.” Click here to visit listing on eBay
