Notes "Roland Synthesizer. The Juno-106 polyphonic synthesizer is the latest addition to the Juno line, which includes the Juno-60 and Juno-6. The 106 features a 61-note, 5-octave keyboard with six DCOs - one per voice. each voice has its own VCF, VCA, and envelope generator. There is also an LFO and a chorus circuit. Performance controls include a portamento section, pitch-bend, LFO trigger sensitivity control, and master volume. The instrument features 128 user-programmable memory positions, arranged in two groups of eight banks each. Each bank holds eight patches. Hands-free switching between memory positions can be accomplished via a rear panel patch shift jack. A cassette interface for off-loading programs is also included. The unit is equipped with MIDI in, out and thru ports. The instrument can receive note event, pitch-bend, LFO modulation, and program change information via MIDI. Stereo and mono outputs as well as a headphone jack are provided. Measurements are 39.05" wide, 4.72" high, and 12.6" deep. Price is $1,095.00. RolandCorp., 7200 Dominion Circle, Los Angeles, CA 90040."

The first Juno to be introduced was the Juno-6, which was released in 1982 and has a very similar architecture to the 106. Its main limitation is the lack of patch memory, which makes it impossible to save patches created on it. The Juno-6 had no external control inputs or outputs except for a VCF control input for sweeping the filter cutoff.

Next came the Juno-60, which added support for storage and retrieval of up to 56 patches via battery-backed memory. These stored patches could also be saved to audio tape. The Juno-60 had the Roland DCB interface, a proprietary interface developed by Roland before the advent of MIDI.

The Juno-106 added a fairly extensive MIDI implementation in place of the DCB interface, and upgraded the available patch storage memory to 128 patches. It did, however, lose the arpeggiator that had been a feature of the 6 and 60. Many people say that the 106 is "thinner sounding" than the first two models, although there is no doubt that it is still certainly capable of generating warm, fat, analog sounds.

There is also a Roland synth called the HS-60 that is nearly identical to the Juno-106 except that it has two built-in 5" speakers and a 16 watt amplifier. The HS-60 was marketed more toward the home user, while the Junos were primarily targeted at the professional market. The HS-60 is also known as the Juno-106S.

Later models were the Alpha Juno 1 and 2, which expanded on the architecture a bit from the earlier models, and provided a more extensive MIDI implementation. They also replaced the convenient rows of sliders with a small alphanumeric display, a number of buttons, and an "alpha dial." The general consensus is that the Alpha Junos sound a little more "digital" and "cold" than the earlier Junos, although they are a little more modern in design and features. The Alpha Juno 2 has a larger keyboard than the 1 (61 keys and 49 keys, respectively), and also implements velocity sensitivity and aftertouch on the keyboard. Both of the Alpha Junos can respond to velocity via MIDI, however. Velocity sensitivity is not a feature of any earlier Junos.
