On the bottom there are some other options. Detune is good for getting a more natural effect, only a little is needed (a little up or down from the center position). Key is not important for non-harmony settings. So selecting C (major that is) scale for Key, which doubles as Am (A minor), means you should play only the notes A, B, C, D, E, F, and G for the most harmonized results. These harmonizer effects are intended to be played in a certain major or minor scale. The Pitch menu lets you select pitches like +7 or -7, or harmonies which are intelligent pitch shift effects. Or the dry and wet signals mixed (a harmony). The Blend control will let you use a fully shifted output, The result is this pitch 'pedal' simulation that has most of what is great about guitar harmonizer pedals, and still preserves the signal's integrity. The effect is meant to combine old styles of pitch shifting with the quality you expect from modern plug-ins. Pitchproof is a free audio plug-in that can shift the pitch of the input.
