This keyboard is the most famous of the
gabber/
trance/
acid/
hardcore dance genres, with users from
808 State to
The Prodigy. It features an
analog tone generator utilizing
digital filtering technology, which in the
early eighties when it was made available was a huge accomplishment.
The major difference between a Roland Alpha Juno-1 and an Alpha Juno-2 is the Alpha Juno-1's lack of aftertouch and velocity when outputting to an amplifier. They will both function equally when outputting using MIDI, however.
Also of note are pc programs which allow the entire memory banks of these synths to be transferred via MIDI, rather than recorded to cassette tape a la Juno-1 or cartridge.
