Let your personal robot do the talking
Use direct access tools to instantly change a male voice to a female voice and vice versa, bring in sounds from space, or transform yourself into a robot, benevolent or malevolent. A powerful Vocoder is also available, which you can drive through numerous synthetic waveforms, the E-4's Pitch functions, or an external MIDI keyboard, for endless texture variations.
Loop and Scatter
Thanks to the 24-second Looper, a single voice can sound like a large choir. By layering vocal layers one after another, the E-4 lets you create incredible vocal textures. You can then slice them using the Scatter effect, whose elements you control with a simple rotation of a knob.
Connect and start
Connect a vocal mic to the front panel input, or use a communication headset, or the built-in mic to your headphones, to bring some vocal fantasy to your next online show. Synchronize the E-4 with the other AIRA Compact instruments, T-8 Rhythm Machine and J-6 Chord Synthesizer, to create complete songs. Or use it as an interface to music production software, a mobile music app, or physical instruments, via USB-C or MIDI.

The E-4 is capable of creating original vocal parts anywhere and anytime. Its lithium-ion battery gives you 3.5 hours of battery life, and its Roland build quality is sure to give you years of use.
