Description
The 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.
Jam instantly.
AIRA Compact invites you to start making music the instant you power up. With friendly controls, inspiring sounds, and loads of creative tools, you can quickly turn simple ideas into off-the-cuff masterpieces.
Uncommon versatility.
However and wherever you make music, AIRA Compact instruments are there for you. Stow one in a pocket or backpack and compose on the go. Mix and match them for busking, club performing, and livestreams. Or use them as high-quality sound generators and input devices for larger-scale performances and computer music production.
Renowned sonic DNA.
Driven by the advanced Analog Circuit Behavior (ACB) technology found in our top-line instruments, AIRA Compact delivers the real-deal sounds behind decades of hit music. Create with the authentic voices of Roland icons, including TR rhythms, TB basses, JUNO synths, VT effects, and more.
Class-leading connectivity.
AIRA Compact provides ample I/O to interface with everything in your musical world. Synchronize and monitor multiple AIRA Compact instruments from one unit, connect with stereo audio and MIDI devices, and communicate with computers and mobile music apps via USB-C.
Small and mighty.
AIRA Compact strikes the perfect balance between portability and power. Each model is small enough to slip in a pocket and features a tactile panel to jump-start your creative flow. Onboard lithium-ion batteries provide hours of continuous fun per charge. And with Roland’s famous build quality, your AIRA Compact is ready for years of musical exploration.
