Purpose

Tune corrects the pitch of a monophonic source, pulling each note toward the nearest pitch in a scale. It covers natural, transparent tuning as well as the hard, snapped sound, depending on how fast and strong you set it.

TouchDesigner Use

Insert it inline on a voice or lead. Wire audio into in and out onward. Wire a scale source into scale to set the target notes, then set Strength for how far each note is pulled and Speed for how quickly it gets there.

Inputs And Outputs

• Input 0: in is the signal to tune. It accepts mono or stereo PCM and is required.
• Input 1: scale accepts a scale ring that sets the target notes. Optional.
• Output 0: out emits the same shape as the input.

Main Controls

• Strength: how strongly each note is pulled to the scale. Low is subtle; full is fully snapped.
• Speed: how fast pitch moves toward the target. Fast gives the hard, instant snap; slow glides between notes.
• Formant: keeps the vocal character steady as pitch is corrected, for a more natural result.
• Bypassglide: lets natural slides between notes pass through instead of being corrected.

Notes

• Tune works on one note at a time, so it is best on monophonic vocals and leads, not chords.
• For the classic hard-tune sound use high Strength and fast Speed. For gentle pitch help use lower Strength and slower Speed.
• For a fixed pitch move rather than scale correction, use Pitch Shift.
