Inspirational Roland vocal processing.

The E-4 combines powerful voice transformation tools and standard vocal effects with a tactile interface that's meant to be played. This sleek, wicked machine packs a treasure trove of top-quality processing into a go-anywhere gadget that's endlessly enjoyable and incredibly affordable.

Perform with sound.

Working with the E-4's inviting panel, you can go from traditional vocal enhancements to punchy beatboxed grooves to strikingly alien soundscapes - all in a single performance. Choose different sonic shapers, trigger looper controls, run through Scatter effects, and adjust pitch, formant and more in the flow.

Harmonic explorer.

Take your singing to the next level with automatic harmonic effects. Set the key and chord voicings on the fly and give any song a head-shaking touch. And with Auto Pitch, you can set everything from subtle vocal corrections to the hard-tuned sounds heard in mainstream pop tracks.

Awaken your inner robot.

Use direct access tools to instantly change your voice gender, conjure sounds from outer space, or transform yourself into a mechanical personality (good or evil, it's up to you). There's also a powerful vocoder that you can control from a large pool of built-in synth waveforms, the E-4's pitch functions or an external MIDI keyboard to achieve an endless variety of textures.

Loop and Scatter.

Turn one voice into an entire orchestra using 24-second loops. Overdub layer upon layer with the E-4's effects to create wild, vocal-driven rides. Then slice and dice the sound with the expressive Scatter knob, which cuts the sound into colorful pieces that you control with a twist.

Link up and go.

Connect a handheld microphone to the front input to perform, or use a gaming headset or the inline microphone on your headphones to give your next live stream or podcast a fresh voice. 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.

Everywhere at once.

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