Timing Sine Modulator Freq
If you select Sine as the Timing Modulation Source, this control sets the modulator frequency. As with most Generator frequency controls, its operation is affected by the Frequency Step setting. This defaults to Direct, with 1 Hz steps when you use the scroll arrows.
There is only one Sine source that is shared among the Quant, Bias, and Shift modulators on any Stream, so changes in one dialog will change this value in the others in that stream. Although any that use the Sine source will have the same frequency and phase, you can use other frequencies (or waveforms) via Stream Modulation.
The frequency resolution of this and all Generator frequency displays may be set between 0 and 9 decimal places via the Frequency Places option in the Frequency Step Mode dialog, invoked by clicking the button below this. (The button shows the current Step Mode, which defaults to Step Direct.)
Use Quant., Bias., or Shift. prefixes in addition to channel and stream prefixes to specify the modulator for the TmModFreq command.
For example, L.1.Quant.TmModFreq=10 will set Left Stream 1 Quant Modulator Frequency to 10 hertz. TmModFreq=>1 will increment or TmModFreq=>-1 will decrement the current Modulator Frequency by 1 Frequency Step. Only +/-1 step is allowed per command, but the step size and type can be controlled via the Frequency Step dialog. Note: The Frequency Step setting affects the behavior of most Generator frequency controls.
