VoxSyn Pro turns your voice into the most flexible vocal sound generator ever. Instantly following even subtle modulations of pitch and spectral changes of your voice VoxSyn Pro creates signature vocal sounds far beyond traditional vocoding.

Talk or sing into the microphone and you’ll trigger various synthesizer sounds following your voice pitch or the notes touched on the hexagonal keyboard / external MIDI Keyboard. The basic sounds are selected from a vast pool of predefined sounds from the famous TERA synthesis engine which can be further expanded by its unique random sound generator.

The harmonic table note layout visualises your voices pitch in realtime and also let you play notes for more traditional vocoder effects.

VoxSyn Pro is AUv3 compatible and can be used in AU Host apps like Garageband, Cubasis, AUM and many more.

Important: Users of VoxSyn should wait for the App bundle to save money.

Excited, but need help

The things I can see this doing are amazing, but I’m having issues getting it going in GarageBand. Is this the correct platform to ask a question?

Only good if you don’t mind static

After adjusting every setting I can think of, swapping out a few different microphones, and scouring the web for support, I’ve come to the conclusion that this app just doesn’t work. The output of this vocoder is so distorted that it’s unusable. I can’t find any way to get a good, clear vocoder sound. The audio clipping is terrible, every input sounds as if the mic is in your mouth and the gain is all the way up. Maybe you’ll have better luck, but this was pretty disappointing for me.

Doesn't work for loopy pro

I bought this to use in loopy pro. Put it on as an effect for a channel and when I put it on the channel it mutes all channels and no audio comes through. Put it on a pre recorded channel and it shows audio but again mutes all audio. If you could assist me I would change my review. Seems like a cool concept if it worked.
