Sing and jam with powerful voice transformer features, premium effects, and the built-in looper!
The E-4 Voice Tweaker is an exceptionally creative jam box that functions as a harmonizer, auto-pitcher, vocoder, looper, and glitcher for your voice and any other signals you feed into the E-4. Manipulate your sound through intuitive hands-on control and combine the Voice Tweaker with other AIRA Compacts and electronic instruments in perfect sync.
Inspiring Roland Vocal Processing
The E-4 combines powerful voice processing tools and classic vocal effects with an intuitive interface that invites experimentation. Packed with top-tier processing options, you can take this ultra-compact instrument anywhere. The E-4 is simply endless fun and surprisingly affordable.
Perform with Your Sound
The E-4’s intuitive interface gives you full control during your performance—optimize your voice with traditional effects, craft punchy beatbox grooves, or transform your vocals into stunning soundscapes from another world. Choose from various sound shapers, trigger looper parameters, use scatter effects, and seamlessly integrate pitch and formant adjustments into your workflow.
Discover Harmony
With the E-4’s automatic harmony effects, take your singing to the next level. Quickly and easily set key and chord voicings to give your songs a special flair. The auto-pitch function offers a wide range—from subtle pitch corrections to heavily tuned vocal sounds typical in modern mainstream pop.
Loop and Scatter
The 24-second looper turns a single voice into a full orchestra. Layer voice upon voice and transform them with the E-4’s effects into extraordinary sound structures. Then simply turn the scatter control to slice your sound into colorful and distinctive sonic morsels.
The Robot Within You
With the E-4, you can change your voice’s gender, conjure alien sound worlds, or instantly transform into a robot (whether it’s a good or bad robot is up to you). A powerful vocoder is also available to combine your voice with a wide selection of built-in synthesizer waveforms, the E-4’s pitch functions, or an external MIDI keyboard.
Plug In and Play
Connect a handheld microphone to the front input for vocal performances, or use a gaming headset or the inline microphone of your earphones to enhance your next livestream or podcast with extraordinary vocal experiments. Expand your possibilities by combining and syncing the E-4 with other AIRA Compact models like the T-8 Beat Machine and the J-6 Chord Synthesizer. Additionally, use the USB-C or MIDI ports to interface with computer DAWs, mobile music apps, and hardware instruments.
Instantly and Anywhere
With the E-4, you can creatively process your vocals anytime, anywhere. The built-in lithium-ion battery provides up to 3.5 hours of runtime. Thanks to Roland’s reliable build quality, you don’t have to worry about your inspiration and magic ending unexpectedly.
Comfortable Stereo Headphones
The KH-238 delivers a full, balanced sound with rich bass and clear highs. It offers plenty of volume while maintaining clean and precise stereo imaging. The softly padded, wide headband is length-adjustable with 12 steps on each side for a perfect fit. For even more comfort, the ear cups rotate on two axes. The thick, soft padding of the circumaural cups also provides good external noise isolation. The integrated volume control on the cable is always within reach, making it easy to use with a PC or mp3 player. The 3.5 mm stereo jack ensures excellent transmission quality, and a 6.3 mm stereo adapter is also included in the package.
