Keyboard bass

Similar instruments were produced in Japan under the "Raven" and "Rheem Kee Bass" [sic] names.

Stevie Wonder pioneered the use of synthesizer keyboard bass, notably on "Boogie on Reggae Woman".

Funk, R&B, G Rap and hiphop musicians such as George Clinton & Parliament, Funkadelic, Roger & Zapp, Dr. Dre, E-40, EPMD, and Kashif used synth bass.

Since the 1990s, MIDI keyboard controllers, often smaller 25-note models, have been used by some groups to play bass lines with virtual instruments such as synthesizers and samplers.

MIDI keyboards are used by bedroom producers and studio musicians alike, thanks to their affordability, portability, and the fact that they can be used to control multiple virtual instruments, rather than simply bass.
