Here’s a vintage 1985 Yamaha DX100 Digital Programmable Algorithm Synthesizer keyboard. This particular example, serial number 10475, is in mint, near NOS, 100% all original condition and includes the original owner’s manual, the original box, the original power adapter and the original midi-converter cable! Like all DX synths, the DX100 uses (FM) Frequency Modulation synthesis. While the DX100 is not as flexible nor powerful as a DX7, it is the next best things, and does have some very cool sounds. It is most renowned for its great analog bass sound that is awesome for any electronic musical styles. With 49 mini-keys, small pitch and mod wheels, and guitar strap pegs make this synth very accessible for live keytar use. If you’re willing to spend a little time with it, it has a lot more potential than than most entry level/toy synths.
