NotesTwo models were released: the Alpha Juno (AJU-1/AJ-1) (1985), and the Alpha Juno 2 (AJU-2/AJ-2) (1985), 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.
