Bill from Gearwire demos Sugar Bytes’ Robotronic.
Robotronic is a vocoder which can process mono and stereo input signals, includes sampler and synthesizer and offers Frequency Focussing and Formantshifting.
Robotronic is available in Mac VST and AU, and PC VST for 79€ / 99$.
Sorry, I’ve tried this one but a freeware TAL vocoder beats it completely. I just couldn’t get a nice and stable output from this one no matter what I did. Tried compressing the carrier, the modulator, too, externally, but nothing could make it work stably. 🙁 Shame. TAL Vocoder on the other hand is so easy to handle, or the Prosoniq one.
