Key

which notes it is allowed to sing
hold a s d f g h j k (sharps on w e t y u) or a MIDI keyboard in MIDI mode

Tune

how hard it pulls to the nearest allowed note

Formant is the size of the throat you seem to be singing through. Off, it keeps its own size while the note moves. On, it moves with the note, which is the chipmunk and the monster.

Motion

wobble it adds on its own

Vibrato is the small wobble a singer adds. Gargle is the same idea taken too far: up to two octaves deep, up to fifty times a second.

Choir

three extra voices, in key with you

Off, a voice counts steps of the scale, so it stays in key. On, it counts semitones and can land outside it.

Spikes

damage, on purpose
or press space

Out

how much of it you hear, and how loud
