“Yamaha DX21 keyboard synthesizer working. I have a Motif and no longer need this . It has been sitting in the closet for a few years so when I fired it up I had to reload the patches from the onboard memory. Worked like a charm. Probably needs the onboard battery replaced. Lots of videos on you tube showing how to do it. LCD screen starting to “bleed” around the edges, doesn’t effect it’s usability at all. You can find back-light replacements on Ebay for under $30. Classic Yamaha sounds. I will include a printed users manual with it.” Click here to visit listing on eBay

Updated with new display.

Sounds great and all buttons, wheels, and functions work good.

I am not familiar with this synth so I tested everything I could figure out.

A little dusty from sitting on a keyboard stand in aq smoke-free studio.”

“Yamaha DX21 MIDI Digital Programmable Polyphonic FM Synthesizer. Condition is “Used”.

LCD screen has developed a black border, but is still readable enough (can be easily replaced with OLED, e.g. from synth-parts.com).

Low buy price to account for flawed display.

Great Vintage synth, at an accessible price.” Click here to visit listing on eBay

“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 search for synths 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 search for synths on eBay
