11. Harmonizer / Pitch Shifter

Only the first versions of this effect developed by a company called Eventide are referred to as harmonizer. The common (and actually accurate) name currently used is Pitch Shifter.

The signal is duplicated without any modulation and the pitch of the second signal is then raised or lowered by a preset interval. If this change is only a few Hz, it gives the effect as if two instruments would play the very same note. This is the most common method to duplicate something electronically, which is the "better chorus" for most.

You can however modify the sound by quints (horrible), quarts (utterly horrible) or any other interval you desire (sheer madness... ).

A great example of this effect in use can be heard on the legendary solo in “Owner of a Lonely Heart” by the one and only Yes. Should an octave be chosen for the shift, it can be achieved by the (more precise) Octaver.

Nope, they won't deal with our homework or our tax declaration, but if we aim to produce quality 2-tone solos live or wish to arrange Brian Mayesque orchestral parts, we can achieve this goal (after a little tinkering).
