Description Find out if this Bypass is active or not.Signature boolean isActive() Returns true if the bypass functionality is on. 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.
