Casio AZ-1
The Casio AZ-1 is a polyphonic MIDI keyboard in the form factor of a keytar. It has a distinctive white body with a long neck, with detailing in a pale blue. This instrument is designed to be played, with the aid of a shoulder strap, in an approximation of an electric guitar. As were many keytars, it was geared towards keyboardists who wanted greater freedom of movement during performances. Features. The AZ-1 features 2 switches, 2 wheels, and 1 slider that transmit assignable MIDI continuous controller data as the user deems fit. It has a pitch wheel for  shifting the sound up or down fractions of a note. Other non-definable controllers include Solo, Sustain, Portamento and a three position octave slider. The AZ-1 has one MIDI output, and can simultaneously transmit on two selectable midi channels. It can send midi program change commands from dedicated program select buttons. Furthermore, its feature set includes both velocity sensitivity as well as true aftertouch.
