Hmmm. Here is some of the code I use:
enum {
kParam_One = 0,
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...
