Released in late 1985 together with the DX27, the Yamaha DX100 is a full 4-op FM synthesizer in a small, portable form factor. It retains all the editing capabilities of its parents at an extremely affordable price for the consumer market — 349£ — being at the time the cheapest way to get into Yamaha's sounds.
With its miniature keys, battery power, strap buttons on the side and mod/pitch wheels conveniently located at the top edge it's perfect to be used standing with a shoulder strap.
Internal memory was also surprisingly bigger than the DX27 or the DX21 given the smaller size. 192 factory voices and a volatile Edit bank that can be filled with voices from the internal memory or from a tape through the cassette port.
Praised by the critic for its convenience and MIDI response, at the time of this review the DX100 remains curiously hard to find online, sellings sometimes at prices higher that the DX7.
