The final peice of the AIRA puzzle is the VT-3 - the vocal transformer based on the classic Boss VT-1 - which allowed for vocal transforming of both pitch and formant separately and was/is a bit of secret weapon for some producers.
Now I'm not sure what happened to the VT-2, if it actually ever existed. But the new VT-3 takes pretty much the same desktop form factor but with the Lime n' Black livery and an interesting Scatter implementation.
Check it out.
