GVST - GSnap
GSnap is an auto-tune effect.
It can be used subtly to correct the pitch of a vocal, or, with more extreme settings, to create a robot-voice effect.
The GUI features a set of 12 knobs which control all of the plug-in's parameters. Each has its function clearly labelled above, and features a user-editable readout below. Additionally, twelve "switches" next to the pitch data view correspond to the twelve semitones of a full octave in the Western chromatic scale, and are used to supplement the "fixed" mode of GSnap. Two further switches allow the user to select between "fixed" or "midi" modes, explained below.
The controls are divided into three groups: Detection, Correction, and MIDI. The Detection section allows you to fine-tune GSnap's ability to deal with incoming audio. Correction determines the method and audible effect of the tuning algorithm. MIDI controls determine how GSnap deals with particular MIDI information.
