Timing Modulation Depth


Macro: TmModDepth

Timing Modulation Depth is used to scale the current modulator source before applying it to the relevant Quant, Bias, or Shift value.

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

For Quant and Bias the Depth may be adjusted from -100% to +100%, while for Shift it ranges from -32767 to +32767 samples or the equivalent in seconds.

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 Quant., Bias., or Shift. prefixes in addition to channel and stream prefixes to specify the modulator for the TmModDepth command.

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

Note that the value you provide for Shift.TmModDepth must reflect the current Smpl/sec state. To be safe, use a SmplSec command to set the desired mode before using this command.
