Presentation
Discover new vocal textures with automatic voicing 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 shifts to today's most radical vocal transformation effects.
Use direct-access tools to instantly change your voice from male to female and vice versa, bring in sounds from outer space, or transform yourself into a robot, benevolent or malevolent. A powerful Vocoder is also available, which you can control with a variety of synthetic waveforms, the E-4's pitch functions, or an external MIDI keyboard, to achieve infinite variations in texture.
Connect a vocal mic to the front-panel input, or use headphones or the built-in mic in your headphones to bring a little vocal fantasy to your next online broadcast. Synchronise the E-4 with the other AIRA Compact instruments, T-8 Rhythm Machine and J-6 Chord Synthesiser, 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, anytime. Its lithium-ion battery gives you up to 3.5 hours of battery life, and Roland's quality design means you'll be using it for years to come.
