Out - This column shows the current DMX output value.
Macro - The macro column displays the programmed macro shape.
Base - The base column shows the programmed base value - if the base value is disabled the value is
displayed as off.
Amp+ - Displays the programmed positive amplitude.
Amp- - Displays the programmed negative amplitude.
Dir - Displays programmed direction. > Indicates forward direction, < indicates reverse direction and
<> indicates a bounce.
Time - Shows the programmed Macro Cycle time
Delay - Shows the programmed delay. Maximum delay value is 8191.
Generic macro parameters
See also generic macro delays Besides the macro shape the generic DMX macro engine also
associates a number of parameters with each DMX control channel.
Setting macro parameters (parameters tab)
Click set to force the displayed parameters to selected fixtures - useful for example when updating
fixtures that are selected as slave fixtures after the values have been set - or to synchronize
parameters for multiple fixtures.
Base value
When a macro is programmed it may contain a base value (default is base-value enabled, value = 0).
When a base value is selected the macro engine will automatically use the base value as reference
value when adding and subtracting values from the macro. When base values are disabled, the macro
engine will add or subtract values from whatever DMX value is generated by other programming
elements. The base value may be disabled for the macro by clicking Off. Right clicking the base value
field brings up a popup menu with often used values.
The advantage of programming a base values is that the resulting DMX output is predictable since it
always combines with the static base value. Disabling the base value allows much more flexibility in
the combined DMX value output - for example, a macro that 'oscillates' around a color on a fixtures
color wheel can be combined with a multi-scene sequence that has different color wheel positions in
each scene. The result is that the color wheel 'oscillates' around different colors depending on the
actual scene of the sequence. The disadvantage to disabling the base value is that some
combinations of DMX values may actually lead to very undesirable effects, such as fixture reset or
lamp off.
Positive and negative amplitudes
The positive and negative amplitudes dictate the 'vertical size' of the macro shape - or in other words
how much the macro shape is amplified. The macro shape contains values ranging from -1 through 0
to 1, so the amplitude values translates directly into DMX min/max values generated by the macro - e.
g. a positive amplitude of 45 will add a maximum of 45 to the output value (when the shape is at max
value). Note that when the amplitudes are negative, the shape is mirrored across the shape 0-value
line basically inverting the shape.
