Reinvent yourself vocally!

The Boss VT-1 Voice Transformer gives you total control over your voice - timbre, tone, pitch . . . everything. Independent control over pitch and formant makes this possible. Essential to voice processing, the VT-1 offers high-quality digital stereo reverb. Apart from being the ultimate DJ effects unit, the VT-1 will benefit virtually any application where signal manipulation is needed. The user-friendly tabletop design features 4 sliders and a Robot button for precise realtime adjustments.

The Pitch slider raises or lowers the fundamental note pitch.
Formant slider adjusts pitch of formant components, creating an effect virtually the same as changing vocal cords and the shape of the vocal tract.
Mix Balance slider allows mixing dry and effected voices.
Reverb slider adds stereo reverb equivalent to high-quality dedicated units.

The Robot mode changes your voice into a robot's (like the classic sci-fi movies) making the pitch of the input voice uniform and flat, thus creating a mechanical-sounding voice. Combine this with Pitch and Formant slider adjustments for astonishing vocoder effects.

Along with 4 preset patches, there's an additional 4 user patches. You can convert the presets into user patches. Then simply call up a patch to instantly change voices.

Perfect for any applications featuring voice.
Extremely useful for DJs, the VT-1 lets you configure user patches with completely different voice characters and rapidly switch between them to take on different roles. The Robot button is perfect for use as a vocoder without a keyboard, so you can use it for DJing techno and dance music programs. It's also an ideal tool for broadcasting applications as well as for video narrations.
