LFO Section
The parameters in this section control the LFO that can be used to modulate either the
frequency (Pitch) of the tracking oscillator (vibrato), or the Formant Shift (Shift)
parameter of the synthesis filter bank.
It allows synchronous/non-synchronous modulation in bar, beat (triplet) or free values.
 Wave buttons: Select the waveform used by the LFO. A selection of Triangle, falling
and rising Sawtooth, Square up and down around zero (bipolar, good for trills),
Square up from zero (unipolar, good for changing between two definable pitches), a
random stepped waveform (S&H), and a smoothed random waveform is available.
Simply click on the appropriate button to select a waveform type.
 LFO Formant Shift Intensity slider: Controls the amount of format shift by the LFO.
 LFO Pitch Intensity: Controls the amount of modulation (vibrato) by the LFO.
 LFO Rate knob and field: Sets the speed of the LFO modulation. Values to the left of
the center positions are synchronized with the sequencer’s tempo and include bar
values, triplet values and more. Values to the right of the center positions are non-
synchronous and 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 one bar percussion part which is being cycled. 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 for existing audio material.
