Studio Vocal Suite Anywhere You Need It

Portable Vocal Processor and Looper with Auto-pitch, Harmonizer, Vocoder, Onboard FX, Audio, MIDI, Sync I/O

Roland’s Aira Compact series merges the musical magic of decades of innovation with unmatched portability. This on-the-go vocal processor draws from Roland’s robust repertoire to deliver a host of FX in a battery-powered, pocket-sized module. Boasting satisfying tactility, the E-4's streamlined interface encourages exploration of its Auto Pitch, harmony, and vocoder functions, alongside a host of FX and processing modes, with no shortage of I/O options. Rock it on its own or plug it into your system — whichever route you choose, the techno-wizardry of this sleek system lets you construct the perfect vocal visage.

Powerful, portable play

The E-4’s deceptively simple interface hides a world of vocal opportunity. Auto Pitch, harmony, and vocoder effects are just the beginning. Reverb, tempo, delay, and chorus effects are freely available throughout the looper’s 24-second recording space, all in real time. The Scatter knob yields compelling rhythmic flares, situated alongside pitch, formant, and reverb sliders, dealing a satisfying user experience. Shape your output with the onboard low-cut filter and noise gate, with unlimited overdubbing, undo/redo, and automatic bpm detection. Craft everything from serene vocal vistas to volatile soundscapes, thanks to the E-4’s intuitive integration that is comprised of a 1/4-inch mic input and audio, MIDI, and sync I/O. Class-compliant USB-C/MIDI interfacing requires no additional drivers, and the onboard pitch and vocoder’s melodic parameters can be controlled externally.
