21. Octave Shifter
< Miscellaneous >
This algorithm synthesizes polyphonic octave‐up and octave‐down component of the input signal
and blends these components with the direct signal to produce the composite output signals. The
output level of each component are independently adjustable for maximum flexibility.
On top of this we added a reverb algorithm which smooths out the residual artifacts of the pitch‐
shifting algorithm. Beyond the smoothing effect, it turns out pitch‐shifting and reverbs go really
well together, we found them to be natural pair that complement each other.
P R I M A R Y
[ Speed ] = Sub‐Octave
Controls the amount of sub‐octave
component added to the mix.
[ Depth ] = Octave
Controls the amount of octave
component added to the mix.
[ Tweak ] = Dry
Controls the amount of dry signal added
to the mix.
Reverb only?
By muting the Sub‐Octave and Octave components, you get only the dry signal + the reverb.
Now you have a great sounding reverb algorithm which you can use stand alone, or paired
with the other on‐board modulation algorithms.
