Roland AIRA Compact E-4 Voice Tweaker

The Roland Aira Compact E-4 Voice Tweaker is the ultimate tool for vocalists and music producers, providing the ability to change your voice in multiple ways. Taking inspiration from the Roland VT-3, the E-4 is jam-packed with vocal processing tools including auto-pitch, vocoder, harmonizer and much more. As well as being a powerful performance tool, the E-4 can also be used to transform your vocals whilst recording too.

Dedicated sliders are included for changing the pitch and formant of your voice, as well as a slider that controls the onboard reverb effect - perfect for adding some more depth to your voice. Create sequences, loops and performances using the 24-second looper complete with unlimited overdubbing, undo/redo and automatic BPM detection. One of the most unique features is Auto Pitch, which will automatically change the pitch of your voice to match the music; capturing that classic 'auto-tune' style effect for live performances.

A range of onboard effects allows you to texture/add colour to your sounds including a premium-grade reverb, echo, tempo delay and chorus effects. You can even dial-in rhythmic effects using the large 'Scatter' knob, ideal for adding some flair to your performances. The compact design and built-in Lithium-ion battery make the T-8 highly portable - perfect for musicians on the move.

24-second looper with advanced controls and effects

Capture your inspiration when it strikes with the onboard looper, providing 24-seconds of recording time with unlimited overdubbing. This opens a world of possibilities when it comes to creating loops, sequences and even full-blown vocal pieces. If you’re a beatboxer, this looper can be great for building up loops from the ground up. For example, you could lay down a drum beat then add a bassline, then a melody; all using your voice! Championed by the likes of Beardyman, this live-looping process is made easier than ever with the E-4

Not only that, but you can add some texture and process your vocals with a range of studio-grade effects on offer. Add some depth to your sound using the reverb or echo effect. There is also a tempo-synced delay and an array of chorus effects to choose from.

Portable design with versatile connectivity

Designed for musicians and performers on the go; the Roland Aira E-4 features a highly compact design that will fit in your lap and be stored easily within most backpacks. Play and perform wherever you go thanks to the built-in Lithium-ion battery, which provides up to 4.5 hours of playback from a full charge. Not only that but the housing of the beat machine is constructed using robust materials to ensure a durable enclosure. Roland has also used high-quality components throughout the manufacturing process including premium-quality rubber pads for the various controls, ensuring a long lifespan.

The rear panel of the Aira Compact E-4 features a wide variety of connection options including audio, MIDI and sync I/O, as well as an AIRA Link port for connecting multiple Aira Compact units together.
