“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

“For sale i’ve got a Yamaha DX21 FM synthesizer.. 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.”

“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”

” Yamaha DX21 keyboard (Programmable FM synthesiser).

I’ve owned this keyboard for about 30 years but in reality haven’t really used it for the last 25! However, it’s been carefully stored and so is in great condition apart from a few minor scratches and 1 of the slider knobs is missing (as shown in photo – however slider still works fine). The only other known issue is that when it is first switched on, the lowest key occasionally needs to be pressed a couple of times to get it to respond before then working OK. All other keys are 100% reliable. I’ve also checked that I can change sound settings and then swiich off and later back on again without the settings being lost (i.e. an indicator that the internal battery is still OK?).

The keyboard also comes with the original music stand attachment and a basic floor stand (although the latter is not particularly stable – could use a few improvements!). In addition, there is a photocopied version of the owner’s manual.”

” I am selling my old Yamaha DX21. This is an FM Synth, a member of the DX7 tribe released in 1985-ish. So, if you’re looking for that sort of 80’s sound, this would be a good way to get it.

Everything works well. It does need a cleaning. Hasnt been used in a long time. There are some scuffs and dust build up. Nothing that effects the playing or sound. There’s a couple of areas where there are small amounts of glitter nail polish. My friend sold this to me and his little girl used to play it. I’m sure it can be easily removed. I tried to show them in the pics.” Click here to visit listing on eBay
