Stream On / Mod
This determines whether the wave Stream (0-3) will be present in the output when the indicated channel is active. You may have any or all of the streams active at once. In normal stereo mode, all active streams will be added together to build the actual signal output for that Left or Right channel. In Multi-Channel Outputs mode, you can select which active Left or Right streams will be summed for any of up to 8 output channels.
If the Stream On button is not depressed, the stream is totally inactive. It is not sent to the output, and if used as a Modulation Source for another stream it provides a constant zero modulation.
The 'On' label of this button changes to 'Mod' when the stream is used as a modulator by another stream. It may be used by more than one stream at the same time, and in fact may be used by multiple modulators on each of those streams. To find out which streams and/or modulators caused the 'Mod' label on a given stream, you would need to look at the Mod Source controls in all the modulator dialogs of each higher-numbered stream, where any Right stream is considered to be higher than any Left.
Note that in normal stereo output mode, a 'Mod' stream can not be sent directly to either output. That condition remains as long as that stream is selected as a Source by any modulator on any stream, even if that other modulator or stream is inactive.
However, in Multi-Channel Outputs mode, modulator sources may be selected for any output channel. This allows, for example, a dedicated output channel for a modulator signal, which can be used for triggering external devices.
StreamOn=1 activates the current Stream, StreamOn=0 deactivates it, and StreamOn=x toggles the state.
Use channel and stream prefixes to activate this control for any stream, even if its dialog is not open. For example, L.3.StreamOn=1 activates Left Stream 3.
Alternatively, you can use Channel Select variable Ch to specify the channel and stream via Ch.StreamOn=1, where Ch has previously been set to 0-7. (Values 0-3 select L.0. to L.3., while 4-7 select R.0. to R.3).
