Programmable parameters
for visual effects include the follow-
ing items, which may be set independently for each of the four
color channels:
Frequency
– The rate at which lights are flickering. This may
range from 0 to 80 Hz, in 0.1 Hz increments.
Amplitude
-- This sets the brightness level, and ranges from 0
(off) to 255 (maximum).
DC Offset
– Used to set the level of “shimmer” in a light channel.
The default setting is 127, which would modulate normally be-
tween “on” and “off” as determined by the selected waveform. A
setting of 250 for example will barely be flickering. Setting this
to a value below 127 will cause the waveform to
clip
at top and
bottom, which can generate additional interesting visual effects.
Duty Cycle
– This determines the ratio of “on” to “off” time for
the Square waveform. Ranges from 0 (off always) to 254 (on al-
most always).
Phase
– Determines when a waveform starts, relative to the start
of a segment. If this is set to 0 for each color channel, all colors
would be aligned, turning on and off at exactly the same time.
However, very interesting effects are obtained (especially at low
frequencies) by offsetting the phases of the various colors.
See
Color Channel Advanced Concepts, below.
Wavetable
– Use this popdown menu to select sine, square, trian-
gle or user waveforms.
Notice also that there are check boxes below each color channel
which allow you to turn a channel on or off in each segment.
Introduction to Session Creation
A
session
consists of a series of segments; you build a session one
segment at a time. When you first open the RGBW Project editor,
