Perfect for budding vocal artists or seasoned veterans, the Roland E-4 Voice Tweaker is an outrageously jammable box of fun that harmonizes, auto-pitches, vocodes, loops, and glitches your voice and any other audio you feed it. Flip through hands-on controls to manipulate the sound, and chain together additional AIRA Compacts and other electronic instruments to let them ride in perfect sync.
The E-4 is part of an all-new series of ultra-portable, rechargeable instruments with free-flowing features for creative exploration and authentic Roland sounds that bring serious musical power to everyone from hobbyists and gadget collectors to tech-savvy pros. Jam, perform, and develop ideas on the go with friendly controls, inspiring sounds, and loads of intuitive music tools. Users can realize complete compositions with a single unit or expand their possibilities by connecting and synchronizing with other AIRA Compact models. From one master unit, multiple AIRA Compacts can be mixed and monitored with headphones or an external speaker system. It’s also possible to interface with computer DAWS, mobile music apps, and hardware instruments via USB-C or MIDI.
