Thanks Urs,

I was using AnyParameter based on this info from AUComponent.h:

/*
Special note:
A value of 0xFFFFFFFF should never be used for a real scope, paramID or element
as this value is reserved for use with the AUParameterListener APIs to do wild card searches
Apple reserves the range of 0->1024 for Specifying Scopes..., any custom scope values should
lie outside of this range.
*/

However it doesn't seem to work. I finally remembered to check the Swiki (why didn't I look there first???) and found Nikolaus's automation recording page where he goes and listens for all parameters. I changed to doing that (seems like overkill but there you go) and it's now working (well except for the bugs in my code :-)).

Thanks,

Robert.

try kAudioUnitScope_Global and 0 for Element 8-)

Cheers,
