Frequency Sweep On / Off


Macro: Sweep

When this is active, the main Wave frequency for the Stream is swept from Sweep Start to Sweep End over the interval given by Sweep Length, which may be specified in either seconds or samples according to the Samples/Seconds button.

The state of this button is mirrored by the Sweep button on the Stream Dialog, but it can only be changed here; the button on the Stream serves only to bring up the Sweep dialog.


Macro Notes:

L.1.Sweep=1 turns Left Stream 1 Sweep on, L.1.Sweep=0 turns it off, and L.1.Sweep=x toggles between on and off.
