A guitar synthesizer/controller like the DG-20 is any one of a number of musical instrument systems that allow a guitarist to access synthesizer capabilities. The Casio DG-20 was released in 1987. It came with 6 strings on a rubber fretboard with 22 frets. On each note lies a sensor that sends a MIDI signal. It contains 20 preset tones, 10 rhythms and a non-editable "Sustain / Reverb" effect in the Casiotone style. The connector consists of a line output and a headphone jack as well as a MIDI Out port.
When a string is played, the selected tone is triggered, and is output through the built-in speaker. There are two different basic types of preset sounds built-in to the DG-20. Sounds which decay, suck as the accoustic guitar tone, and sounds which are sustained, like the jazz organ tone. Sustained sounds may be cut off by using the mute key, or by releasing the fretbord (which turns off the built-in sensor switch).
By connecting the DG-20 to another MIDI instrument, 6-note polyphonic note messages can be sent to the other instrument. Through this the DG-20 can be used to 'control' or play the other instrument, for a example a synthesizer keyboard with MIDI capabilities.
