Hi Bill,

thanks, I read and tried that. Doesn't work for me. Can somebody post a
short example?

This is my version:
------------------------------------------------------
In "GetParameterInfo"

sInfo.cfNameString = CFStringCreateWithCString(NULL, sInfo.name,
kCFStringEncodingISOLatin1);
sInfo.unit = kAudioUnitParameterUnit_Generic;
sInfo.minValue = 0.0f;
sInfo.maxValue = 1.0f;
sInfo.defaultValue = 0.0f;
sInfo.flags = kAudioUnitParameterFlag_IsReadable |
kAudioUnitParameterFlag_IsWritable |
kAudioUnitParameterFlag_IsHighResolution |
kAudioUnitParameterFlag_HasCFNameString |
kAudioUnitParameterFlag_ValuesHaveStrings;
------------------------------------------------------

Now, *HOW* does the host try to retrieve the string for the current
value? In "GetProperty"? Example please....

Do I need to do something in "GetPropertyInfo" do the host knows it
makes sense to call GetProperty at the time the value changes? What
*exaclty* (example)?

Regards,
Mike
