Paul, It sounds like you're looking for the wrong indication. Knowing
whether the transport is not playing wouldn't suggest that your
render call is not being invoked. Is that what you were saying Bill ?

that is how you can distinguish between an AU that is being called
regardless of whether the host is playing its time line or not..
Sounds like a bug in Logic?

Hi,
I'm trying to check whether my AudioUnit is having audio played
through it or not by calling CallHostTransportState and checking
the isPlaying that it returns.
When I test in Logic Express 7, the plug starts off by reporting
that the audio is stopped (isPlaying is false), and then when I
play audio it reports isPlaying as true, which is fine. The
problem comes when I press stop, and the audio stops playing, the
plug still gets isPlaying true - I would have thought it should
return to false. Am I just using it wrong?
I also find that currentSample just keeps returning 0.0 whether
the audio is stopped or playing.
I'm obviously doing something wrong. Please can someone help. Or
maybe this is the recommended way of testing for whether the audio
is playing?
Thanks
Paul
