About Roland E-4

It's time to elevate your vocal performance with the innovative Roland AIRA Compact E-4 Voice Tweaker. This high-quality, user-friendly, and versatile multi-effects processor and reverb is designed to enhance the sound of your vocals and instruments, offering a wide range of sound manipulation tools.

The E-4 Voice Tweaker is more than just a vocal effects processor; it's a creative powerhouse that allows you to harmonize, auto-pitch, vocode, loop, and glitch your voice or any other sound input. With its hands-on controls, you can easily manipulate the sound and sync it with other AIRA Compacts and electronic instruments for a seamless performance.

This durable device combines powerful voice transformation tools with standard vocal effects, all accessible through an intuitive, tactile interface. From traditional vocal enhancements to punchy beatboxed grooves and alien soundscapes, the E-4 Voice Tweaker can do it all in a single performance.

Explore new harmonic possibilities with automatic harmony effects. Set the key and chord voicing on the fly, and use the Auto Pitch feature to achieve everything from subtle tuning fixes to the hard-tuned sounds popular in mainstream pop tracks.

Unleash your creativity with direct-access tools that allow you to change your vocal gender, create out-of-this-world sounds, or transform your voice into a mechanical persona. The E-4 also features a powerful vocoder, which can be driven by onboard synth waveforms, pitch functions, or an external MIDI keyboard for an endless variety of textures.

The 24-second looper lets you turn a single voice into an entire orchestra, while the expressive Scatter knob allows you to slice and dice your sound into colorful bits. Connect a handheld mic, gaming headset, or the inline mic on your earbuds for performing, livestreaming, or podcasting.

Expand your range by syncing the E-4 with other AIRA Compacts like the T-8 Beat Machine and J-6 Chord Synthesizer, or interface with computer DAWs, mobile music apps, and hardware instruments via USB-C or MIDI.

Portable and reliable, the E-4 Voice Tweaker is powered by a lithium-ion battery that provides up to 3.5 hours of power per charge. With its rugged Roland build, this device is ready to support your inspired magic and mayhem for years to come. Experience the Roland AIRA Compact E-4 Voice Tweaker and transform your sound today.
