Yamaha DX21

“Tested and working. All keys and buttons are working. It has a few marks in places but nothing significant. First and last keys are not as sensitive as the rest but still work when fully depressed (don’t know if this is normal for this model or not). Also missing one of the slider knobs(still works). LCD screen has some minor edge leakage but still works and displays very well. Tested through phones jack into my guitar amp. No other jacks/connections tested as I don’t have the equipment needed at my disposal.
Currently has a 2 pin electrical plug. I can replace this with a 3 pin plug on request (free of charge).”

” Yamaha DX21 MIDI Digital Programmable Polyphonic Synthesizer.

Comes in a 5 STAR flight / transport case which is in top condition (and the keyboard will be shipped in this) which must be worth at least £60.

I have tested all I could on this keyboard :
The screen works ok – there are some black bits at the top and bottom of it that I have tried to show in one picture.
But it does not affect the area where the text is displayed.
All the piano type keys are working properly
All of the green buttons work – i.e. they make whats shown on the screen and the sounds change.
The volume and balance sliders work, and so do the modulation and pitch wheels
The headphone output and A&B outputs are producing sound.
I have not (and cannot) test all the other sockets at the back of the keyboard.” Click here to visit listing on eBay

“Yamaha DX21 FM Synthesizer. It works but the problems are. 4 or 5 keys does not work. They feel great but no sound. The main edit button does not work. It turns on and you can play sounds except for the keys that do not work. That’s why it’s listed for parts or not working. Its my understanding it may only need a cleaning on the inside to get the keys and button trio work but I’m not 100 sure. ” Click here to visit listing on eBay

“Yamaha DX21 Digital Programmable Algorithm Synthesizer for parts/repair. Has some keys that need to be replaced and needs a new power cord. Most of the features appear to work so with a few minor repairs and a clean up and this should be ready to go. I am not an expert on this synth but I did test the functions that I understood and it is producing sounds. I am available to answer more specific questions regarding this item so please ask to get a better understanding of condition if needed. ”
