Yamaha DX21

A consumer level DX synth that sounds just like the DX100 - thin and brittle. Following the DX model this synth also uses FM synthesis which is difficult to master. You will need to program this synth to get better sounds because the presets are only moderately useful. It's capable of a good string, bass and droney-pad sound as well as industrial sound-effects and metallic like sounds.
Still it makes a better option than a DX27 or DX100 because it has the capability of layers and splitting the keyboard and there is a chorus effect. Portamento and a Unison Mono-Mode are also nice features for screaming lead synth performances. For a cheaper source of DX sounds with moderate programmability, check out the DX21. It's been used by Hardfloor, Level 42, Brother Beyond, Astral Projection, Technotronic, Vangelis, and Norman Cook (Fat Boy Slim).

I Love mine,
I paid $100 and at first was put off by the programming and was going to sell it.
Them I found another site that helped with the Programming.
It is a great lead synth and a valuable instrument.

This site brings out some points that the Manuel Misses!
Enjoy!
I was pretty excited, until i plugged it in.
At full volume, the output is barely audible!
Does anyone have any clue as to why, and what I could possibly do to solve this issue?
