Roland VT-4 Overview
The Roland AIRA VT-4 Voice Transformer
is a real-time vocal processor designed to craft and shape your own
custom vocal sounds, from subtle augmentation to radical transformation.
Smoothly alter the pitch and formant of a voice or add heavily
processed vocal effects to your studio work, stage performances,
podcasts, web streaming, and more. All controls are conveniently located
from the front panel allowing you to make quick adjustments without
menu diving or programming. Create remarkable effects such as
harmonizing, vocoding, pitch shifting, hard tuning, and more.
Dramatically change your entire persona from male to female, big to
small, or good to evil.
For controls, the unit features dedicated pitch, formant, balance, and
reverb sliders. A center wheel provides auto-pitch features, while the
dedicated robot, megaphone, vocoder, and harmony buttons allow you to
mix and match effects. Each effect has a selection of one-touch
variations, so you can get different vocoder characteristics, various
lo-fi effects, multi-part harmonies, and distinct kinds of reverb and
delay. Chain your effects, set the controls just how you like them, and
then simply hold down a preset button to save that scene for later. Up
to eight scenes can be saved for instant recall. Changing presets and
tweaking controls is smooth and immediate, with no jarring artifacts,
glitches, or dropouts.
For I/O, a rear panel features a combo XLR-1/4″ connector with
switchable +48V phantom power for use with your favorite condenser
microphone. Outputs are provided by a pair of 1/4″ TRS connectors which
can be configured as either mono/stereo or separate wet/dry channels. A
built-in USB audio interface with adjustable volume level provides
loopback recording to overdub vocals on existing tracks. Power is
provided by either the computer’s USB bus or via the four included AA
batteries.
