Roland AX-Synth

The AX-Synth extends the keyboard to 49 keys (from the AX-7's 45) and also adds dedicated V-Link functionality to control audio and video onstage.

The AX-Synth also has all of the AX-7's stage performance functions such as the touchpad-like pitch bend ribbon, expression bar, sustain switch, and volume control knob, all on the upper neck of the instrument.

The AX-Synth has full MIDI functionality like the AX-7, but also adds an internal synthesizer with 128 voice polyphony and stereo output.

[1] French composer Jean-Michel Jarre used a prototype version of the AX-Synth during the first concerts of his 2009 IN>DOORS tour.

[citation needed] Pop star Lady Gaga has several customized versions of the AX-Synth, used for various performances.
