Stream On / Mod

Controls: Generator Dialog >> Stream >> On/Mod
Macro: StreamOn

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. All active streams will be added together to build the actual signal output for that channel.

If this 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.


Macro Notes:

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.
