Burst Time Modulation Depth


Macro: BurstModDepth

Burst Time Modulation Depth is used to scale the current modulator source before applying it to the relevant base Burst value.

The effective modulated value is equal to the sum of the base value plus the modulator scaled by the Depth.

Negative Depth values simply invert the polarity of the source. If you are using the Sine modulation source, it is the same as setting its Phase to 180 degrees. If you are using Stream Modulation, it is the same as setting a negative Level value on the modulating stream.


Macro Notes:

Use Lag., Rise., High., Fall., Cycle., Count., or Train. prefixes in addition to channel and stream prefixes to specify the modulator for the BurstModDepth command.

For example, L.1.Lag.BurstModDepth=50 will set Left Stream 1 Burst Lag Modulation Depth to 50%. BurstModDepth=>1 will increment or BurstModDepth=>-1 will decrement the current Depth by 1%. Only +/-1% steps are allowed.
