Roland E-4
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. Standard FeaturesĀ
INSPIRING ROLAND VOCAL PROCESSING.Ā
The E-4 combines powerful voice transformer tools and standard vocal effects with a tactile interface thatās meant to be played. This lean, mean machine puts a treasure trove of top-quality processing in a go-everywhere gadget thatās endlessly enjoyable and amazingly affordable.Ā
PERFORM WITH SOUND.
Ā By working the E-4ās inviting panel, you can go from traditional vocal enhancements to punchy beatboxed grooves to striking alien soundscapesāall in a single performance. Select different sonic shapers, trigger looper controls, cycle through Scatter effects, and tweak pitch, formant, and more in the flow.Ā
HARMONIC EXPLORER.
Ā 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. Ā
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.
Ā 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). Thereās also a powerful vocoder, which you can drive from a large pool of onboard synth waveforms, the E-4ās pitch functions, or an external MIDI keyboard for an endless variety of textures.Ā
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.Ā
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.
