The Roland Alpha Juno series of keyboards were analog polyphonic synthesizers with digitally controlled oscillators manufactured by Roland Corporation in 1985.Two models were released: the Alpha Juno (JU-1), and the Alpha Juno 2 (JU-2), which added one octave of notes, a cartridge slot and touch-sensitivity. Alpha Juno synthesizers were notable for their reduced user interface compared to other synths of the day, with a single Alpha Dial replacing many sliders and knobs. The keyboard features MIDI in, out and 'thru', mono, stereo and headphone sockets. It also supports an external footpedal controller, and tape backup.
