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!
