Solo (Left / Right) Output

Controls: Generator Dialog >> Solo
Macros: GenSoloL, GenSoloR

When this is active, only the selected Generator channel is heard. Note that this is not the same as mono, which is where the sound card receives one signal but sends it to both outputs. Instead, Solo is really a stereo mode, with a null signal applied to the other channel.

Changing between Dual and Solo will result in a brief delay before the change takes effect in the output, but there will be a smooth transition with no clicks, as discussed under Left / Right Output Enable.

Note that the Solo buttons are disabled when the Multi-Channel Outputs On button is active in the Multi-Channel Outputs dialog, even if the Generator is off so there is no actual output


Macro Notes:

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

GenSoloR operates the same way for Right Solo.

In some cases you may want to change the Swap state at the same time as Solo, without separate fade transitions. To do this, give the desired Swap state as a second digit. For example, GenSoloL=10 sets Left Solo on and Swap off. Note that when you use this option you must use digits 0 and 1 to set specific states only; you may not use an x to toggle an existing state, nor may you use variables that equate to the apparent values.

GenMode is a read-only variable that returns a single value corresponding to the current Generator mode:

    0 = Normal
    1 = Dual L
    2 = Dual R
    3 = Solo L
    4 = Solo R
