Easy voice transformation with vocoder, lo-fi effects, and synths you can sing

Aggressively processed vocals are common in electronic music today, but producing these effects easily and reproducing them live has been a challenge—until now. With the VT-3 Voice Transformer, you can smoothly alter pitch and formant in real time to introduce heavily processed vocal sounds into your studio tracks and stage performances with zero hassle. On top of that, the VT-3 looks great and works seamlessly with other products in the AIRA series.

  • AIRA Update
    The entire AIRA family has been updated with exciting and useful new features requested by users from around the globe.
    Easy to install and free for all users, this AIRA Update includes enhancements for the whole line, like backup and restore facilities and better overall MIDI management.
    It also provides a wealth of product specific enhancements like external MIDI pitch control for VT-3, tuning control for TB-3, and instrument gain control for TR-8.

Total Transformation

The VT-3 is not just for robot voices (although we totally approve of robot voices). It also has the power to transform your voice into synthesizers, synth basses, hard-tuned and lo-fi sounds, and more. The VT-3 can also be subtle and musical, with built-in reverb, smooth wet/dry fader control, and instant bypass.

Transform your voice with different character types:
- Pop and electro sounds with two distinctive Auto-Pitch effects
- Create VP-330-style Vocoder sounds without the need for a keyboard
- Scatter function for glitchy effects that sound like something’s broken (in a good way)
- Loads of lo-fi character with Megaphone and Radio settings
- Synthetic sounding voices with the Robot button
- Synth, Lead, and Bass settings for synths you can sing

Smooth Control

Built for creative speed and live performance, the VT-3 is meant to be played. It features high-quality specs and sturdy, brightly lit controls that are dead simple to use. The controls and functions are smooth and immediate, with no popping, clicking, or latency issues to worry about, even when switching presets or changing voice characters. Weighing less than two pounds and small enough to slip into a bag, you can take the VT-3 anywhere.

Analog Circuit Behavior (ACB) is the technology behind the authentic sound and responsive behavior of the AIRA products. It faithfully captures the sound and feel of some our most revered classics, using original design specs, consultation with original engineers, and a detailed, part-by-part analysis of each analog circuit in our own pristine units.

Analog electronic musical instruments consist of various analog components including resistors, capacitors, and transistors. The unique sound of analog instruments is due to the distinctive characteristics of the individual analog components. So-called “vintage” instruments, in particular, show extremely distinctive sound and behavior due to the variable instability of the electronic components.

Rhythm machines and synthesizers such as the TR-808, TR-909, TB-303, and SH-101 enjoy entrenched popularity to this very day even though they first appeared over 30 years ago. This is because musicians across the globe have recognized their unique sound and used them to forge entirely new genres of electronic music.

To produce the new AIRA products, we aimed to pick up where these analog classics left off and to develop a completely new technology which models the traditional analog circuits, right down to their behavioral levels.

ACB is drastically different from conventional methods of modeling, and reproduces each analog component by thoroughly analyzing each detail of the original design drawings. By combining the analyzed components in exactly the same manner as the original analog components, detailed characteristics of the original musical instruments emerge and can be reproduced completely.

This analysis requires knowledge of the design and development processes of the original analog instruments. It is not possible to reproduce the original sounds just by logically analyzing the analog circuits. This is because the original engineers used a design approach which maximized the capabilities of the analog components. Throughout the development of ACB, we cooperated with the original engineers who designed and developed these iconic instruments. With their expertise, we could ensure that we fully reproduced the ideal state of their creations.

Utilizing the enormous calculation power of state-of-the-art DSP, ACB not only precisely emulates the analog-specific characteristics or our classic gear, but also delves into areas the original engineers tried to go but ultimately abandoned.

ACB empowers AIRA products to go beyond mere re-creation. It allows us to make instruments that inspire – that respond to your creativity - and make producing and performing electronic music fun again.
