Synth Glossary

Analog Synthesis:
This term is normally used to refer to the tradional synthesis model used by analog synthesizers in the 1970s. It is also known as subtractive synthesis. It involves oscillators, the outputs of which are mixed together and fed into a filter (where certain frequencies are subtracted) after which they are fed through an amplifier. The amplifier and filter are normally also driven by envelope generators....

Juno-6
The Juno-6 is a 6-voice polyphonic, digital oscillator, analog keyboard with a 5-octave, 61-note (C-C) keyboard. Though it only has one DCO per voice, it is said to have a warm and full sound. The DCO is switchable between any or all of the following waveforms: Pulse (with pulse-width modulation from either the LFO or the ADSR), sawtooth, and a sub-oscillator (square wave). White noise could also be mixed in with the oscillators. Each voice has its own VCF with a continuously variable control for keyboard follow, and an input on the back panel for voltage control. There is also a separate high-pass filter, as well as three notch-filter sliders (a simple graphic eq) at 350Hz, 1kHz, and 5kHz. The LFO features controls for rate and delay, as well as a switch that toggles between two modes, auto (modulation starts when set delay time has passed) and manual (modulation starts when the LFO trigger button, next to the mod wheels on the performance panel, is pressed). Only one envelope generator (ADSR) is available for both the DCOs and the VCOs. The Juno-6 featured an arpeggiator with controls for mode, range, and rate with a clock input on the back panel, and a chorus with two buttons, each button adding more chorus. In addition to arpeggiator and filter control inputs, the back panel also had both mono and stereo outputs, a headphone jack, and a sustain/hold pedal input.

About a year later Roland came out with the Juno-60, a programmable Juno-6 with 56 memory locations, their proprietary DCB interface, and a cassette interface.
