Roland - VT-4

Voice Transformer. Aira series real-time vocal processor building on the success of the VT-3.
Harmonizing, vocoding, pitch shifting, hard tuning, and more, with the dedicated pitch, formant, balance, and reverb sliders.
A center wheel provides auto-pitch, while the dedicated robot, megaphone, vocoder, and harmony buttons allow you to mix and match. Each effect has a selection of one-touch variations, so you can get different vocoder characteristics and effects. 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. W/ box
