Multi-Channel Outputs On/Off

Macro: MultiOn

The Multi-Channel Outputs On button in the Multi-Channel Outputs dialog toggles multi-channel mode on and off. (But see Multi-Channel Sound Card Configuration to make sure multi-channel operation is actually enabled.)

Note that the Generator must also be on to get any output signals. In addition, each selected channel must have one or more Stream buttons active, which requires that the corresponding streams in the Left and Right Wave Controls must be active.

If the Generator is on and you toggle Multi-Channel Outputs on without any of the multiple channel buttons selected, the Generator will be forced off. You can, however, have channels selected without active streams, in which case those channels will have zero output signals; other channels with active streams will continue to work normally.

With Multi-Channel Outputs on (in Windows XP only, at present), the normal F9 Volume or dB Slider Dialog will be replaced with the Multi-Channel Volume Slider Dialog.

When the Multi-Channel Outputs On button is off, the normal stereo mode is in effect. That means that all Left streams are summed to create the overall Left channel output, with all Right streams going to the Right output, regardless of Left or Right Streams button settings in the Multi-Channel Outputs dialog.

Macro Notes:

MultiOn=1 sets Multi-Channel Output mode on, MultiOn=0 turns it off, and MultiOn=x toggles between states.
