Tremolo effect question

[EightMilesHigh]

Is there any way mathematically to line up a tremolo effect with the tempo of a song? I know some (including myself) often line it up by tapping a pedal. But is there any way to do this mathematically? I would think there would be, and it would be more precise.

60,000/BPM = 1/4 note in milliseconds.

Multiply by 2 for a half-note, x4 for a whole note, divide by 2 for an 8th note, etc.

My tempo is 139 BPM and I want 8th notes, so 60,000/139 = 431.655.
Dividing it by two yields 215.827. I have a value. So...

Where do I plug in this number? My system has Shape, Speed and Depth. My guess is speed. The number goes from .02 Hz to 20.0 Hz. Shape goes from -100 to +100, and depth goes from 0 to 100.

Also, how would I plug in the number? Based on my second paragraph description of the categories, 215.827 wouldn't fit in any of them. There must be something else I would have to do to the number. Thanks.

Ok, the value 215.827 is in milliseconds.

1 Hz = 1 cycle/second
1 second = 1000 milliseconds
so a cycle of 215.827 milliseconds = 215.827/1000 Hz or 0.215827 Hz
