This bundle from Roland includes three AIRA Compact Series models, including the classic T-8 Beat Machine, J-6 Chord Synthesizer and E-4 Voice Tweaker.

Create infectious tracks in seconds flat with the Roland AIRA Compact T-8 Beat Machine, a miniature rhythm factory loaded with legendary Roland TR drums, plus bass from the inimitable TB-303. Craft on-the-fly acid jams or trap bangers with the intuitive 16-step sequencer, shape sounds with onboard controls—and flip and dice beats with hands-on tools that stimulate ideas and put the fun back into your flow. The Roland AIRA Compact 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. The Roland AIRA Compact E-4 Voice Tweaker is an outrageously jammable box of fun that harmonizes, auto-pitches, vocodes, loops and glitches your voice and anything else you feed it. Flip through hands-on controls to manipulate the sound, and chain in AIRA Compacts and other electronic instruments, and let them ride in perfect sync.

T-8 Beat Machine

Build beats with the boom, pop and sizzle of sounds from the TR-808, TR-909 and TR-606 drum machines, paired with the shapeshifting low end of the dynamic TB-303 Bass Line. The T-8 exudes classic Roland character, thanks to the same Analog Circuit Behavior (ACB) tech found in the TR-8S, TB-3 and other high-end AIRA gear. Loaded with comprehensive I/O, the Compact T-8 is ready to be the rhythmic centerpiece of any electronic music setup. Connect and sync with other AIRA Compacts like the J-6 Chord Synthesizer and E-4 Voice Tweaker. Or, interface with computer DAWs, mobile music apps and hardware instruments via USB-C or MIDI.

The Compact T-8 features six drum tracks and one bass track brought together with a player-friendly interface for fast recording and hands-on tweaks. Capture and fire off 64 patterns with up to 32 steps each, and shape sounds and control parts as you go with an array of dedicated knobs and buttons. Backed by the TR-REC step sequencer loved by beatmakers since the 1980s, the Compact T-8 Beat Machine makes it simple to develop ideas without ever stopping the action. Real-time recording, sub steps and velocity further expand the programming power at your fingers. And with deep features like step loop, pattern shift and probability, it’s easy to deliver dynamic performances with constantly evolving grooves.

J-6 Chord Synthesizer

With 100 chord sets spanning a wide range of genres, you’ll always find fresh fuel for songs and jams with the Compact 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 AIRA Compact 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 nonstop with a press of the hold button.

Once you’ve got a chord progression in mind, bring it together with the AIRA Compact J-6's 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 AIRA Compact J-6 puts the influential synth sound behind decades of hits into your pocket or backpack. Roland’s 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. It 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 AIRA Compact 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.

E-4 Voice Tweaker

The AIRA Compact E-4 combines powerful voice transformer tools and standard vocal effects with a tactile interface that’s meant to be played. This lean, mean machine puts a treasure trove of top-quality processing in a go-everywhere gadget that’s endlessly enjoyable and amazingly affordable. By working the Compact E-4’s inviting panel, you can go from traditional vocal enhancements to punchy beatboxed grooves to striking alien soundscapes—all in a single performance. Select different sonic shapers, trigger looper controls, cycle through Scatter effects, and tweak pitch, formant and more in the flow.

Take your singing to the next level with automatic harmony effects. Set the key and chord voicing on the fly and bring head-turning flair to any song. And with Auto Pitch, you can dial in everything from subtle tuning fixes to the hard-tuned sounds heard in mainstream pop tracks. Use direct-access tools to instantly change your vocal gender, conjure sounds from outer space or transform yourself into a mechanical persona. There’s also a powerful vocoder, which you can drive from a large pool of onboard synth waveforms, the AIRA Compact E-4’s pitch functions or an external MIDI keyboard for an endless variety of textures.

Turn one voice into an entire orchestra using the 24-second looper. Overdub layer after layer with the AIRA Compact E-4's effects to create wild, vocal-driven rides. Then slice and dice with the expressive Scatter knob, which chops your sound into colorful bits that you control with a twist. Connect a handheld mic to the front input for performing, or use a gaming headset or the inline mic on your earbuds to bring fresh vocal fun to your next livestream or podcast. Sync with other AIRA Compacts like the T-8 Beat Machine and J-6 Chord Synthesizer to expand your range. Or, interface with computer DAWs, mobile music apps and hardware instruments via USB-C or MIDI.

Roland's AIRA Compact E-4 creatively accentuates vocals anytime and anywhere. The lithium-ion battery provides up to 3.5 hours of power per charge, and the rugged Roland build will support inspired magic and mayhem for a long, long time.
