The DX-27 is a full sized keyboard version of the DX-100. Like all DX's it uses (FM) Frequency Modulation synthesis. It's not the easiest form of synthesis to program but can result in some excellent sounds.

Extended information

The DX27 is not as flexible nor powerful as a DX7, but it does have some cool sounds. It is most renowned for its great analog bass sound (Patch #01) that is awesome for techno, house, jungle, and acid music styles; it's very gritty, the bass tone with gristle! However, any other preset sounds that you'll find in the DX-100 are pretty bad. Though the DX-27 adds a standard 61 note keyboard it still lacks filters, arpeggiators, effects or performance wheels and controllers.

Pictured above is the DX-27S which adds built-in speakers for the home-user. It also has a stereo chorus effect and Pitch bend & Mod wheels and has support for a Breath Controller.
