Synths ⇝ Yamaha ⇝ Yamaha DX21

The DX21 is a 4-operator FM synthesizer and one of the most limited of the DX line due to the keyboard's lack of both velocity and aftertouch sensitivity. It has 8 different algorithms available, similar to the other 4-operator Yamaha FM synths, and is patch-compatible with some of the other 4-operator devices, such as the DX27, DX100, and TX81Z.
