Here is one way to do it...I see that the Volume Control changes the waveform based on a log scale while scaling the waveform with the multiply command is a linear scale. I assume this makes a difference when using the sound card to appropriately scale audio, but doesn't have a bearing when outputing an arbitrary waveform signal. Am I accurate in this assumption?
According to the above, I should just set the Volume to max and scale from 1 to 0. Is there any reason I should scale by a log scale as the Volume Control does?
Thanks for all the help.

As long as you do not see any clipping of the output signal. You may set the volume to max, and use the scale function I suggested. As long as the signal is OK by you it does not matter much which constant you use on the volume control. If you use a constant volume setting. You may also place the volume control outside the main loop. As it will not be needed to set the volume on each iteration, only once.
