Octaver

This plug-in can generate two additional voices that track the pitch of the input signal one octave and two octaves below the original pitch. Octaver is best used with monophonic signals.

Direct: Sets the level balance between the dry signal and the wet signal. A value of 0 means that only the generated and transposed signal is heard. By raising this value, more of the original signal is heard.
Octave 1: Adjusts the level of the generated signal one octave below the original pitch. A setting of 0 means that the voice is muted.
Octave 2: Adjusts the level of the generated signal two octaves below the original pitch. A setting of 0 means that the voice is muted.
