“Yamaha DX21 Synth in lovely condition with custom case. It has been kept safe in its case for many years. There are no blemishes on the top, sides, front or rear and only minor stand marks underneath. I doubt that there are many classic synths of this age in as good a condition as this instrument.”

“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”

” 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

“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
