We normally do not use NULL for the object param - that's probably
the problem. Try specifying self (obj-c), or this (c++)

Hmmm. Here is some of the code I use:

kLfo1RateParam = 1,
kNumberOfParameters = 2

AudioUnitParameter parameter[] = { { 0, kParam_One,
kAudioUnitScope_Global, 0 },
{ 0, kLfo1RateParam, kAudioUnitScope_Global, 0 } };
int i;
for (i = 0; i < kNumberOfParameters; ++i) {
parameter[i].mAudioUnit = mAU;
NSAssert ( AUListenerAddParameter (mParameterListener, NULL,
¶meter[i]) == noErr,
@"[CocoaView _addListeners] AUListenerAddParameter()");
}
So the second element of the AudioUnitParameter should be unique,
right?
Strange...

Its probably rejecting the second one because you're adding an
identical entry? An unique identity is formed by:
Listener
"Object" (this is the object arg to the listener APIs)
ParamInfo - AU, Scope, Element, ParamID
