DX-21

“I don’t know much about this keyboard or the history of it. All I know is that when I plug it in, it turns on, but there’s no sound, even when plugging headphones in. It also looks like the modulation wheel is slightly tilted, and one key is slightly below the other keys. It has signs of use and age shown in the pictures. Selling this sold as is for parts or repair, no returns. I’m sure someone who works on these can fix it right up. This will be packaged well for shipping. ” Click here to visit listing on eBay

“Here is a working Yamaha DX21. It’s got a few scratches here and there cosmetically but nothing major. When i first got it there were no factory patches loaded upon startup. I transferred factory patches via MIDI SYSEX.Now you have to hit FUNCTION and then LOAD SINGLE and press YES to load them in. Once done you can select and play and edit these patches as normal, or just load an init patch and program a sound from scratch. Also includes owner’s manual.” Click here to visit listing on eBay

“This DX 21 is in need of a simple (kind of) battery replacement as the factory patches will be erased when you power down. All of the sounds are loaded on the on board ROM, and you can see by the picture that the Grand Piano patch was loaded, so it will definitely load sounds. Battery is a little tricky to get to and I just elected to sell it cheap rather than work on it, as I am not using the keyboard at this time. All functions seem to work , but I haven’t spent a ton of time with it. Ships in a nice flight case, and I will refund any shipping amount over the $80.00 if it costs less to ship. ” Click here to visit listing on eBay

“Yamaha DX-21 digital synthesizer in good condition. Keyboard has been tested and all basic features & sounds are working properly. Synth dates to the mid to late ’80s. No dead keys. All buttons/switches/controls are functioning. Pitch bend and modulator wheels both work well. Display is clear and working. I did not test any of the more advanced features (memory/etc) but I guarantee those features to work properly. Slider controls operate smoothly with no distortion. Keys are all responsive-no sticky keys. Cosmetically, instrument looks good overall but does have some surface wear. There are some scattered spots of minor surface rust on top cabinet panel. The rust spots are no bigger than an 1/8″ in dia and the rust is very superficial. Rear panel of synth is fully intact. The large Yamaha logo on rear panel has some faint blue paint overspray on it. Power cord is intact and in good condition.” Click here to visit listing on eBay

It will need the factory patches reloaded onto it as it has a garbled screen and will only make sound when the factory reset procedure loads up the Init sound patch. I have replaced the old battery with a new slotted removable battery holder for easy change. All notes respond on keyboard. Cosmetically it’s got some scratches and scuffs but not too bad. Comes with the owner’s manual.”

“Working well considering it’s age, pitch bend wheel is a bit wonky but works fine. Has had new fader caps on volume/balance/data entry sliders. D# in the second octave can be a little sticky, probably easy to sort by opening up and cleaning the key bed, I’m not familiar enough with the DX21 to take it apart myself.” Click here to visit listing on eBay

“Yamaha DX21 FM Synthesizer TESTED AND WORKING

Everything works, it is very good condition

A bump underneath the keyboard is a sign of wear but this is only cosmetic everything internally works well

It has some patches I programmed in it pretty much all of the top presets are all my own patches

I would keep it but I want to go to a different type of synthesis and I don’t want to have more than one synthesizer at one time”
