used yaamahdx21 “I’ve used this synth for over 14 years now, easily programmable, capable of a good string, bass and droney-pad sound as well as industrial sound-effects and metallic like sounds.
Being able to split two sounds on the keyboard is a huge bonus, have fun.
Keyboard stand included. ” Link

Yamaha DX21 vintage keyboard in working order. There is one key (fifth white key from left) that has a very slight tarnish which might have been someone dropping a cigarette on to the key and removing it quickly many years ago!” Link

dx21 “I have a VINTAGE YAMAHA DX-21 KEYBOARD / SYNTHESIZER for sale. This keyboard is fully tested, works great and has a new memory battery freshly installed. . The only thing “wrong”, I could find is the green number 4 button takes a little extra effort to activate and there is some slight discoloration around the edges of the display, (see pictures). Cosmetically its about an 8.5 out of 10. This is a professional keyboard with a metal case, not a toy. I am very picky about my descriptions. This way you know exactly what you are buying. ” Link

dx21 “This was a perfectly functioning DX21 until the goons at Parcelforce decided to break it. It no longer powers on, and the bottom left corner has been snapped off. No mean feat for heavy duty Yamaha synths! The low C key nearest the damage now also sticks and doesn’t have the correct action. I can enclose the broken off bjt of plastic that could be stuck back on; please see photos for that.” Link

dx21” Used very good condition Yamaha DX 21 synth. You can extensively edit patches using the digital menu. There are 128 presets included as well. Very nice digital Synth. Everything is in perfect working order and was owned by one person.

The original manual is included. I will also throw in a foot pedal which can be used to add sustain or portamento effects.

Sorry for the high shipping, it’s on the heavier side.” Link

dx21 “This classic 80s synth is a close relative to the famed DX7. The DX21 is really similar and a great synthesizer in its own right. What it lacks are the patches unique to the DX7, but they are both frequency modulation synthesizers.

I am a sound designer in Nashville, and over the years I have made my own custom patches on this machine. Upon request (before the auction ends or after you win) I can send you some audio samples of the included sounds. It’s a great synth and I have enjoyed working with it.” Link

yamahadx21” DX21 keyboard. This is a US import so it requires a transformer. It worked when it was powered up about four years ago and it has been stored ever since. However I’m selling as ‘for parts not working’ as I don’t have a power supply to test it with. Comes in a home made (not by me) case. I’m not a keyboard player so I don’t know any more about it. I just need it out of the way. Collection only please. Cheers. ” Link
