The Roland VT-4 Voice Transformer is a powerful voice changer for your desktop or studio. Transform your podcast, gaming or recorded vocals with weird, whacky and wonderful vocal FX in real time.

From Augmentation to Full Transformation

Have you ever longed for an all-in-one Vocoder, Harmonizer, Auto-Tune and Pitch Shifter? The VT-4 is here!

The VT4 features a highly tweakable array of Harmonizing, Vocoder, Pitch Shifting and Hard Tuning effects. Hook it up to a MIDI Keyboard, or simply plug in a microphone and start having fun with hands-on control.

Using the Roland VT-4 Voice Changer, you can quickly transform your pre-recorded or real-time vocals with a multitude of subtle or simply insane effects. It's all there at your fingertips, without complicated menus or extensive technical know-how.

Roland VT-4 Key Features:

  • Desktop Vocal Effects Processor
  • Robot, Megaphone, Vocoder, Harmony and Reverb effects
  • Easy-to-use Interface, and no fiddly menus!
  • High Quality 24-bit, 192kHz sound processing
  • USB and MIDI In Connections

The Ultimate Voice Changer

Modern musicians and studio engineers are becoming increasingly adventurous with vocal processing. Through the works of Daft Punk, Kanye West and T-Pain, voice manipulation and Auto-Tuning has become much more prominent in Western and Urban music styles.

Designed for creativity and live performance, you can continue to alter the effects while you perform. This is an excellent way to keep your vocals sounding fresh, musical and captivating for your audience.

Furthermore, because of its compact design and battery operation, the VT-4 Voice Changer is extremely portable. Ideal for taking on the road!

Great Sounding, Transformative Effects

As a performance-focused vocal effects processor, Roland have designed the VT4 to give you great quality effects without needing a computer.

Because of this, you have seriously high-end quality effects ready to use, straight out of the box.

Pitch and formant effects are on hand with smooth, instant control because of the dedicated faders.

Using these, you can dramatically change up your vocal sound on the fly and even completely change your vocal persona. Go from male to female, big to small, grandiose to diminutive; the Roland VT-4 lets you do it all.

You can even use multiple effects at once to easily create complex vocal effects.

Each effect has a number of variations and you can run effects through each other to come up with new sounds and layer them up.

Once you've created something you like, you can just hold down a preset button and save your new sound for later.

Additional MIDI Control

While the Roland VT-4 Voice Transformer has been designed for use on its own, harmonising and vocoding without any external input (other than your voice), it also has connectivity options for even more potential.

For example; you can connect a MIDI keyboard to the VT-4, for even more expressive possibilities. With a connected MIDI keyboard, you can control the auto-pitch, harmony and vocoder engines - all in real time with the notes you play on the keyboard.

You can create instant multi-part harmonies that follow your chords or hard-tune your voice to specific notes as you sing for absolute pitch perfection.

The VT-4 Voice Transformer even boasts USB-audio connectivity, giving you virtually limitless potential. Using this, you can alter your voice for all sorts of applications such as YouTube videos, podcasting, game streaming or more. Your imagination is the limit.
