Description Deactivate the bypass functionality. In other words, the wrapped UGen WILL have an effect on the UGen patched to this Bypass, as if it was in the signal chain in place of this Bypass.Signature void deactivate() Returns None Related BypassExample /* bypassExample<br/>
* is an example of using the Bypass UGen in a continuous sound example.
* Press the space bar to activate and deactivate the Bypass.
