The Ultimate SynthDB | Yamaha DX21

Browse

Description	A consumer level DX synth that sounds just like the DX100/DX27 - 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.
