Timing Modulation Dialog


Macros: TmQuantMod, TmBiasMod, TmShiftMod

The Quant, Bias, and Shift controls have their labels on small pushbuttons at the left of the controls. For most applications you can just ignore these buttons, and use the edit box of each control normally. Pressing the button opens a dialog to enable modulation of the parameter for special cases.

Note that although the three dialogs are very similar, they control separate and distinct modulation processes, each with its own parameters. However, there is only one Sine source for all Timing modulators on each Stream, which is shared among the three dialogs. Timing modulators that have Sine selected as the modulation Source may have different modulation Depths, but they share the same Sine frequency and phase. If you need these to differ, select another stream as the modulation source.

If you use stream modulation with Multi-Channel Outputs, instead of normal stereo, the modulator stream itself can be used as an output. This can be used to supply a modulation sync signal to an external device.


Macro Notes:

If the Timing Dialog is open, TmQuantMod=1 opens the Quant Timing Modulation dialog, TmBiasMod=1 opens the Bias dialog, or TmShiftMod=1 opens the Shift dialog. Giving 0 instead of 1 will close the dialog, and giving x will toggle between open and closed.

Note that you do not need to open the dialog to set its controls directly via macros. You will, however, need to use a Quant., Bias., or Shift. prefix in addition to channel and stream prefixes to specify which dialog control to change. See examples for individual controls.
