The Roland AIRA E-4 is a powerful tool that'll completely change the way you write, sample, and record. With this unit, players can harmonize vocals on the fly, add autotune, dirty things up with bit-crushed distortion, and more. If you've been looking for a vocal processor that's equally suitable for the stage and the studio, the AIRA E-4 is an excellent choice.
Like all units in the AIRA series, the E-4 has an intuitive interface that allows users to start creating right away. Just connect a microphone to the 1/4" input on the front of the unit, and you'll be ready to begin processing vocals and making beats. Once connected, users can adjust the low-cut filter and the noise gate to remove unwanted background sounds from their mix. Players can also use the right slider to control reverb, echo, delay, and chorus effects, opening up a new realm of sounds to explore. And thanks to the E-4's auto-pitch feature, users can fine-tune their vocals with subtle pitch correction or apply aggressive autotune for a robotic effect.
That's not where the E-4's use ends, though - it has a wide array of unique features that can bring a new element to live performances. Its harmony program can add up to three voices at different intervals that'll lock to a selected key and scale, a great tool for filling-out chorus sections. It also has a vocoder built-in that adds several synth waveforms and a Scatter knob that applies tempo-length effects like slicing, panning, and bit-crushing. For players who want to take things one step further, the E-4 has a looper that can store approximately 24 seconds of audio. Use this to create short samples that can be inter-spliced whenever needed or to build entire songs live.
With that said, we've barely scratched the surface of the E-4's capabilities - you'll have to try one out yourself to uncover its true potential. Check one out today if you're ready to take your sound to the next level.
