The VT-4 is an impressive new effects processor that shapes and mangles the human voice. It is so easy to use and very effective.  From the subtle to the extreme, the VT-4 helps you manipulate your vocals into unique sounds that stand out. The layout is designed for everything to be hands-on with simple controls and USB-audio capabilities, plus it’s easy to integrate into your setup. Its performance-oriented interface allows the user to efficiently operate the controls while performing, with instant control over both pitch and format, having dedicated faders for each. It can also be battery powered, ready to travel.

Effects such as Harmony, Vocoding, Pitch Shifting, Hard Tuning, plus others will be at your fingertips. Complex vocals effects can also be done using multiple effects at the same time. Users can save their effects chain as presets for later use. Each effect has variations for quick access such as distinct kinds of reverb and delay.

The VT-4 can also have another form of input via MIDI to be even more creative, permitting effects such as Harmony and Vocoder to be used with chords and notes. Hard tuning vocal inputs to specific pitches become possible as well as keyboards being played with a vocoder effect. Creating multi-part harmonies with voicings that follow your chords can also become a reality.

The user can change his or her vocal character. The user's imagination can create endless possibilities, making the VT-4's real-life usages limitless. From podcasts to live stage performances to online gaming, the user can alter his or her voice to take on a particular persona.
