Roland’s Aira Compact series merges the musical magic of decades of innovation with unmatched portability.

What Roland Says...

The J-6 Chord Synthesizer is an endless well of musical inspiration, pairing a powerful chord sequencer with the lavish tones of the renowned JUNO-60 synth. Generate soul-stirring song ideas in seconds, and experiment with styles and variations to coax dancing lines and rhythmic patterns from your chords. Add lush effects to frost your sound, and expand your possibilities by interfacing with other AIRA Compacts, MIDI hardware, and music production software.

With 100 chord sets spanning a wide range of genres, you’ll always find fresh fuel for songs and jams with the J-6. There’s no need to know chords or theory to make cool music—simply call up a set and compose chord progressions on the fly with one-touch presses on the keyboard. Generate ideas for new tunes, create accompaniment for live performances, or send chord information to other MIDI gear.

Using the J-6’s style banks and variations, it’s easy to infuse static chords with dynamic energy and compelling movement. Transform an idea with sweeping arpeggios and rhythmic phrases, and keep the groove running non-stop with a press of the hold button.

Once you’ve got a chord progression in mind, bring it together with the J-6 chord sequencer. There are 64 patterns with up to 64 steps each, and you can quickly enter chords, style variations, single notes, and tempo changes in each step to mold your masterpieces.

After you’ve captured a pattern on the J-6, hit play and inject even more color with tactile controls. Select different synth presets, tweak the filter and envelope in real time, and complete the picture with customizable reverb and delay effects.

The J-6 puts the influential synth sound behind decades of hits in your pocket or backpack. Our acclaimed Analog Circuit Behavior (ACB) technology realizes the famous JUNO-60 voice in flawless detail, complete with 64 presets derived from the original. Use the J-6 engine with the chord sequencer, play it from the onboard keyboard or an external MIDI controller, or use it as a sound module in an expanded setup.

The J-6 has the connectivity you need to integrate with other AIRA Compacts and larger music rigs. Back your chord creations with drums and bass from the T-8 Beat Machine, and add evocative vocal textures with the E-4 Voice Tweaker. Or interface with computer DAWS, mobile music apps, and hardware instruments via USB-C or MIDI.

Compact and convenient, the J-6 is ready to deliver instant inspiration everywhere you go. The lithium-ion battery provides up to 4.5 hours of runtime per charge, while the rugged Roland build ensures years of musical pleasure.
