Dual (Left / Right) Output

Controls: Generator Dialog >> Dual
Macros : GenDualL, GenDualR

When Left Dual is active, the Left signal goes to both outputs and the normal Right signal is ignored. The reverse is true when Right Dual is active.

If you have only a single output active and neither Dual nor Solo selected, the single channel is sent to the sound card in mono mode, where it is directed to both Left and Right outputs. If you select Dual, the sound card is operated in stereo mode and the same signal data is sent separately to each of the channels.

The audible result is the same, but the advantage of Dual is that you can switch back and forth to Solo without an audible click. There will be a slight delay before any change made here reaches the output, but it will be a smooth transition as discussed under Left / Right Output Enable.


Macro Notes:

GenDualL=1 turns Left Dual on, and toggles Left Solo, Right Solo, or Right Dual off if previously on. GenDualL=0 turns Left Dual off (without changing anything else), and GenDualL=x toggles between the two states.

GenDualR operates the same way for Right Dual.
