Autotune VST Plugin - Free Download

Amazing autotune VST plugin

GSnap, by Graham Yeadon, is arguably the best free autotune / vocal harmonizer vst effect there is! It can be used subtly to correct the pitch of a vocal or instrument, or, with more extreme settings, it can be used to create the famous robot-voice effect. The Gsnap auto-tune plugin can switch between automatic mode and manual treatment to correct individual notes that need a bit more work. GSnap requires a monophonic input signal to operate, so remember to add stereo effects after the Gsnap plugin.
This free auto-tune vst plugin is simply amazing. If you only want one autotune / pitch correcting vst effect, this is the one you want!
