List of Roland keytars

AXIS

Roland's first keytar was the

AXIS An axis (plural ''axes'') is an imaginary line around which an object rotates or is symmetrical. Axis may also refer to: Mathematics * Axis of rotation: see rotation around a fixed axis *Axis (mathematics), a designator for a Cartesian-coordinate ...

(officially the AXIS-1, leading to its frequently being confused with the AX-1). It was produced between 1985 and 1987, and is notable for being a significantly different design than later Roland keytars. It features a 45-note keyboard that is sensitive to both velocity and aftertouch; aftertouch sensitivity was removed on the AX-1 and not restored to any Roland keytar until the AX-Edge in 2018. It uses three conventional wheels for pitch bend, modulation, and volume, rather than the pitch ribbon and modulation pressure bar on later designs. It is AC-powered with no battery option – a proprietary multipin cable connects the AXIS to a Power Supply Unit on the floor. The PSU has non-slip rubber sides and features a power cable, power switch, multipin cable input, and MIDI output, as well as a footswitch for sustain while playing.

AX-1

The Roland AX-1 was produced between 1992 and 1994. Like the AXIS, it does not produce sounds, but controls other devices (such as keyboards, sound modules and samplers) via

. The industrial design of the Roland AX-1 was done in a basement studio in London, U.K. by two designers, David Sherriff and Andrew Leggo, who ran a small design studio called Space Logic. The electronic design and engineering was done by Roland Europe, Italy.

AX-7

The Roland AX-7 was manufactured from 2001 to 2007. This modern instrument contains many more advanced features than early keytars such as its predecessor, the Roland AX-1, and the
