Roland AIRA Compact E-4 Voice Tweaker Vokalprocessor

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.
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.
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.
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.
