Play with sound
Using the E-4's control panel, you can enjoy traditional sonic enhancements, but also punchy Beatbox grooves, or other-dimensional soundscapes. Choose your transform parameters, loop controllers, switch between Scatter effects, and adjust Pitch and Formant on the fly.
A harmony explorer.
Discover new vocal textures with Auto Harmonize effects. Adjust key and chord progressions on the fly to give your songs a whole new dimension. With Auto Pitch, you can achieve everything from subtle vocal adjustments to today's most radical vocal transformation effects.
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.
Everywhere at the same time
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.
