Intensity and Int via Whl
The Intensity slider controls the amount of Formant Shift modulation by the Shift LFO.
The Int via Whl slider for the Pitch LFO features a multi-part slider. The intensity of LFO
pitch modulation can be controlled by the modulation wheel of an attached MIDI
keyboard. The upper half of the slider determines the intensity when the modulation
wheel is set to its maximum value, and the lower half when set to its minimum value.
By clicking and dragging in the area between the two slider segments, you can
simultaneously move both.
Rate Knobs
These knobs determine the speed of modulation. Values to the left of the center
positions are synchronized with the sequencers tempo and include bar values, triplet
values, and more. Values to the right of the center positions are non-synchronous, and
are displayed in Hertz (cycles per second).
Note: The ability to use synchronous bar values could be used to perform a formant
shift every four bars on a cycled one bar percussion part. Alternately, you could
perform the same formant shift on every eighth note triplet within the same part.
Either method can generate interesting results, and can lead to new ideas, or a new
lease of life on old audio material.
