I'd like to react to changes of the activated/deactivated state of my plugin in FCPX/Motion, but I can't seem to find any info on how to achieve that in the FxPlug API.

Attaching the debugger I can see that the host calls into parameterChanged: with parmID=1 once I click on the Fx bypass checkbox in FCPX.

However, I already have a parameter that's mapped to paramID 1 and I wouldn't be abgle to remap it without breaking compatibility with sessions saved with existing versions of our plugins.

I also tried removing the mentioned parameter in order to retieve param 1's state as a BOOL via the FxParameterRetrievalAPI presuming it reflects the desired bypass state...without success, however, since getBoolValue:fromParm:atTime: always returns NO for that parameter.

Any hints?

Thank you!
