TUNE

Pitch correction that keeps the singer in it. The box listens for the note and moves it onto the nearest note of the key, a few tens of milliseconds behind, keeping the octave when the fundamental is weak and moving the pitch without moving the vowel. KEY follows the song's key unless you fix one. RETUNE at SNAP is the hard sound everyone knows; 20 to 60 ms is the one nobody notices. AMOUNT goes all the way or half. FORMANT holds the vowel or lets it move for the small-and-fast sound. NOTES are the twelve landing places, yours to pick.

• Leave KEY at SONG and the box is right without a word from you
• RETUNE 40 ms, AMOUNT 70%: in tune, with the singer still in it
• Pick three NOTES and a hook lives on them

Four to a socket, in order: sound runs through the slots top to bottom. Open the box and every knob is in real units; BYPASS takes it out of the path without losing its settings; the presets are along the top; any knob learns a controller and gets an automation lane.
