Roland JU-06A Synth Module

"The JU-06A is our most accurate and best replications of the legendary JUNO-106 and JUNO-60 synthesisers. We took the meticulously modelled ACB (Analogue Circuit Behaviour) engine from the limited edition JU-06 and added a JUNO-60 model, as well as the apreggiator from this legendary product from Roland's heritage. ACB models every single component of a synthesizer, from the circuit board, the behaviour of the parameters and even tonal properties. Both the JUNO-60 and JUNO-106, despite their similar appearance, had very different and instantly recognisable sounds due to their different filters and oscillators. Having both models available on the JU-06A gives you access to a huge variety of sounds, that means you'll never be short of inspiration. Whether you want the iconic warm pad sounds, thick pulse-wave bass sounds, icy cool lead/appreggiated sounds and of course, the quintessential JUNO Chorus effect (complete with optional noise), the JU-06A is the vessel that gives you all these textures that the JUNO is renowned for. Bank A even has the same patches of the first bank on the original synthesizers. We have whacked on a 16 step sequencer, in-built speakers and it can be battery powery, meaning you can use the JUNO sounds whereever you go. Partner with the K-25M for the perfect dock/addition of keys. You can also use the DK-01 if you would like to angle the synth on your desktop. The JU-06A comes with a 3 year warranty and lifetime tech support with myself." GAK's Roland/Boss Product Specialist, James Purvis.

Overview by GAK

The Roland JU-06A is a modelled synthesizer module, replicating the famous JUNO-60 and JUNO-106 Roland synthesizers. Powered by ACB (Analogue Circuit Behaviour Modelling) Roland have meticulously modelled each individual component of these vintage synthesizers, right down to the circuit board. ACB technology is Roland's most accurate and most authentic sound engine in their arsenal, and the JU-06A behaves just like the original models due to this advanced sound engine.

The JU-06A has 4 voice polyphony, all the original parameters from the JUNO-60 and JUNO-106, but on a compact and easily portable chassis. You can switch between the JUNO-60 or JUNO-106 models, giving you access to their different oscillator and filter types. Not only that, Roland have put the arpeggiator from the JUNO-60 on the front end, so both synth models can be controlled by it. It features the world famous JUNO Chorus effect, complete with optional noise. There's even a 16 step sequencer for good measure too.

It can be programmed as a stand alone module, or connected to your favourite MIDI controller, allowing you to play it just like a keyboard. We suggest using it with the K-25M, as this also allows you to angle the synth module for easier access to the front panel. It also hae it's own built in Audio Interface over the Micro USB port. Connect it with your favourite DAW for seemless integration.

Pair it with other modules from the Roland Boutique Range, for a small but mighty setup! You can even connect two JU-06As together for more polyphony

Everything You Love About Vintage JUNOs—In One Synth

For many, vintage Roland JUNO synthesizers define the sound of the ‘80s. Increasingly popular on the used market, many keyboardists either want one, or deeply regret selling one back in the day. With the JU-06A you get the sound, look, and features of both the JUNO-60 and JUNO-106 in one reliable, modern instrument that you can take anywhere.

Two classic JUNOs in one. The JU-06A is the best of the JUNO-60 and JUNO-106 in one synth. It has the continuous high-pass filter of the 106, the envelope-controllable pulse-width-modulation of the 60, and the unique filter behaviour of both, instantly switchable from the front panel. The sound is indistinguishable from its vintage counterparts, even while tweaking controls or using extreme settings. And no vintage JUNO would be complete without the swirling sound of its legendary chorus, faithfully recreated, right down to the lovable (and thankfully adjustable) noise.

Arpeggio, chord memory, and step sequencer. While you may prefer the filter of the JUNO-106, you might miss the arpeggio function on the JUNO-60. The JU-06A has both—and throws in chord memory and an onboard sequencer to boot. Creating sequenced lines with chord memory results in polyphonic phrases so thick they have no business coming from something that fits in your backpack.

MIDI, USB and external clock input. With USB audio/MIDI and full-sized MIDI jacks, you play and synchronize with just about any piece of gear. There’s also an external clock input, so you can sync to vintage analog instruments or modern Eurorack systems. Not only is this convenient, but using external clock to drive the onboard sequencer can result in unexpected phrases, rhythmic variations, and other happy accidents.

Add keys and more. Its compact size means the JU-06A fits just about anywhere, easily controlled from a master keyboard or DAW. Add a DK-01 Boutique Dock for a polished look and three convenient tilt positions. Or add a K-25M Keyboard Unit and you have a totally self-contained, portable instrument offering an unleashed experience free of wires and other complications.
