Time Modulation
Time modulation is a very
effective tool that adds
modulation or movement to the
time of any individually
selected node or linked stereo pairs. Using the same familiar
controls as the Pan Modulation, the up and down arrows lets
you choose between graphically illustrated presets representing
a variety of sine waves, triangle waves, inverted triangle, square
waves and two separate envelope followers.
You can change the phase of a selected
waveform by grabbing the graphic with
your mouse and moving it to the left or
right to place the modulation in or out of
phase. The phase increments are
measured in degrees and are represented
by the top set of numbers just to the left of the waveform display.
Two separate envelope
followers are included in the
collection of preset
waveforms. Although an
envelope follower is not technically a waveform, the regular
controls will apply. To control the threshold of Envelope
Modulation 1 and 2, use the mouse to grab the horizontal white
line.
The modulation RATE is controlled with a
slider, and is measured in beat ratios that are
directly linked to the master Tempo. The
DEPTH of the modulation is measured in
percent. The block numbers just to the left of
the sliders represent the values of rate and depth sliders.
Clicking the words TIME MOD causes the letters to turn yellow
and allow the settings to apply to all of the selected nodes.
