The Design of the Roland Juno Oscillators #MusicMonday
What do Cyndi Lauper, The Eurhythmics, a-ha, Daft Punk, the Chemical Brothers, and Vangelis have in common? They all love Roland’s Juno oscillators. Everybody knows about the 303 and the 808, but here’s a breakdown of the design of the just as important Juno oscillators from Stargirl Flowers:
Roland introduced the incredible Juno-6 and nearly identical Juno-60 in 1982. The Juno was a 6-voice polyphonic synthesizer that was an incredible value considering its array of features. The Juno notably featured digitally-controlled analog oscillators. The DCO was designed to overcome the tuning instability of the usual voltage-controlled oscillators (VCOs) in contemporary polyphonic synthesizers. The DCOs operate with the same fundamental analog circuitry but differ in that they are controlled by a microcontroller. This imparted a unique sound to the Juno series and one that’s become a favorite of many musicians.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
