Key Features

ROLAND VOCAL PROCESSING: The E-4 combines powerful voice transformer tools and standard vocal effects with a tactile interface that's meant to be played. This lean, mean machine puts a treasure trove of top-quality processing in a go-everywhere gadget that's endlessly enjoyable and amazingly affordable.

PERFORM WITH SOUND: By working the E-4's inviting panel, you can go from traditional vocal enhancements to punchy beatboxed grooves to striking alien soundscapes-all in a single performance. Select different sonic shapers, trigger looper controls, cycle through Scatter effects, and tweak pitch, formant, and more in the flow.

LOOP AND SCATTER: Turn one voice into an entire orchestra using the 24-second looper. Overdub layer after layer with the E-4's effects to create wild, vocal-driven rides. Then slice and dice with the expressive Scatter knob, which chops your sound into colorful bits that you control with a twist.

CHANNEL YOUR INNER ROBOT: Use direct-access tools to instantly change your vocal gender, conjure sounds from outer space, or transform yourself into a mechanical persona (good or evil is up to you). There's also a powerful vocoder, which you can drive from a large pool of onboard synth waveforms, the E-4's pitch functions, or an external MIDI keyboard for an endless variety of textures.

EVERYTHING IN ONE BOX: The added 10ft Roland MIDI cable features spiral shielding and durable nickel-plated connectors, a reliable choice for your cable needs in the studio and on stage. The included 6ft stereo plug cable is ideal for connecting a stereo audio output, such as an mp3 player or phone, to a stereo audio input, such as the auxiliary input on a car stereo system. Keep your sound module in mint condition with the included polishing cloth.
