Yamaha DX21

Essentially a miniature DX7, the Yamaha DX21 is a digital controlled bi-timbral programmable digital FM synthesizer with a four operator synth voice generator which was released in 1985. It uses sine wave-based frequency modulation (FM) synthesis. It has two FM tone generators and a 32-voice random-access memory (RAM), 32 user voices and 128 read-only memory (ROM) factory preset sounds. As a programmable synth, it enables users to create their own unique synthesized tones and sound effects by using the algorithms and oscillators.

This particular unit is in very good condition - there are some light marks and scratches and the Data Entry slider is missing it's tip, however the keybed is in great condition and all buttons and programs work perfectly. There is some evidence of tape over the logo and various parts of the chassis but this has been mostly removed. This one has been upgraded to have an LED backlight, making this the ultimate gigging and studio DX21. It's also has a fresh memory battery installed to keep your patches intact for years to come. Please note this unit is 100V AC. Comes with it's original branded DX bag!
