Hi Floris,
IsActive() does return true because Logic sets the render callback in
the setup phase. It does so because changing the callbacks requires
an uninitialize/initalize cycle which could break playback if
adjusting the sidechain while in playback.
I don't think there is a way for you to reliably get this setting
from Logic - why are you interested in this?
Best,
Stefan

Hi all,
We're currently building a stereo AU effect plugin with a side
chain. Everything seems to work fine; the plug-in has two input
busses and one output bus, reports the correct channel info and
passes AU Validation as expected.
To check whether the second input put (the side chain) is actually
being used, we use IsActive():
if (HasInput(1)) {
sideChain = GetInput(1);
if (sideChain->IsActive()) {
result = theSideChain->PullInput(ioActionFlags, inTimeStamp, 1,
nFrames);
...
...
}
}
Now here's our problem: when opening the plug-in in Logic Pro 7.2,
the side chain option is shown correctly and it set to 'none'.
However, even when set to 'none', IsActive() returns true, while I
would expect in to be false...
Any clues on why this happens? Is this normal behaviour, a bug in
Logic or should I be checking other things to test whether the side
chain is being used?
Thanks!
