with complete confidence that the instrument would be in tune." It also included performance controls, an arpeggiator, and an ensemble effect. Roland released another version, the Juno-60, in September 1982, which added patch memory (allowing users to save and recall up to 54 sounds) and a DCB connector, a precursor to MIDI. Production of the Juno-60 ended in February 1984, when Roland released the Juno-106, Sounds and features The Roland Juno-6 and Juno-60 are single-oscillator analog synthesizers, featuring a high-pass filter, a low-pass filter, a single ADSR envelope and a single LFO. Many polyphonic synthesizers contained two oscillators, so to make up for the single oscillator, Roland implemented an onboard chorus effect as well as a high-pass filter that would boost the bass level in its lowest position. The chorus effect is engaged using two push buttons which give slow modulation rates of 0.4 Hz and 0.6 Hz. Additionally, the two buttons can be engaged simultaneously to create an even stronger chorus effect. Although regarded as noisy, the Juno chorus effect is considered a signature feature of the Juno-60. It was based around bucket brigade designs from the 70s, such as those in the Roland DC-50 “Digital Chorus” effect unit from 1976 and uses two identical circuits incorporating two ICs (MN3009 and MN3101). Impact The Juno-60 was widely used in 1980s pop, house, 1990s techno music, and even today by acts including Enya, Vince Clarke, Howard Jones, Nik Kershaw, John Foxx, a-ha, Billy Idol, Fingers Inc., Berlin, Eurythmics, A Flock of Seagulls, Cyndi Lauper and Wham!. It was also a key instrument in Chicago house. The 2010s saw a resurgence of popularity among indie and electro acts such as Metronomy, driving up the price on the used market. Successors Roland followed up the Juno-60 with the Roland Juno-106 in 1984. The Juno-106 featured MIDI, had patch storage of 128 sounds, replaced the arpeggiator with a portamento effect, and introduced Roland's now-standard left/right/push performance lever for pitch-bend and modulation. The Alpha Juno 1 and Alpha Juno 2 were released in 1985. These synths offered new programming capabilities, backlit screens and a new interface. The Juno 2 also featured a velocity‑ and aftertouch‑sensitive keyboard as well as a cartridge slot for storing patches. They were seen as too expensive and difficult to program, so were a commercial failure, ceasing production in 1986. Roland revived the Juno name in the 00s, releasing the
