Roland E-4 Voice Tweaker
MPN #E-4
Portable vocal processor and Looper with pitch correction, harmonizer, vocoder, reverb, MIDI, and more
A VOCALIST?S BEST FRIEND.
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.
INSPIRING ROLAND VOCAL PROCESSING.
The 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.
PERFORM WITH SOUND.
By working the 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.
HARMONIC EXPLORER.
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.
LOOP AND SCATTER.
Turn one voice into an entire orchestra using the 24-second looper. Overdub layer after layer with the 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.

CHANNEL YOUR INNER ROBOT.
Use direct-access tools to instantly change your vocal gender, conjure sounds from outer space, or transform yourself into a mechanical persona (good or evil is up to you). There?s also a powerful vocoder, which you can drive from a large pool of onboard synth waveforms, the E-4?s pitch functions, or an external MIDI keyboard for an endless variety of textures.
LINK UP AND GO.
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.
EVERYWHERE AT ONCE.
The 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.
