Roland Aira Compact E-4

This on-the-go vocal processor draws from Roland's vast repertoire in sound manipulation and offers a variety of ways to shape your voice, all in a compact, portable format.

The E-4's clean user interface offers a pleasant feel and combines many features and functions under the hood.

Auto Pitch, Harmony and Vocoder effects are just the beginning. Reverb, Tempo, Delay and Chorus effects are available throughout the looper's 24-second recording range - all in real time.

The Scatter control provides wacky rhythmic effects alongside the Pitch, Formants and Reverb controls. With the built-in low-cut filter and noise gate, unlimited overdubbing, undo/redo, and automatic bpm detection, the module is especially suited for performers, whether studio or live.

The 6.3mm microphone input as well as audio, MIDI and sync inputs ensure that the E-4 works with other hardware or DAWs despite its compact dimensions. The USB-C/MIDI interface requires no additional drivers, and the built-in pitch and vocoder parameters can be controlled externally.

The E-4 Voice Tweaker is either powered via USB, or can also be operated on the go for up to 3.5 hours via the integrated rechargeable battery.
