Hi,
My AudioUnit plugin has 2 relational parameters and other parameters.
For example, I have the following parameters.
Param A (required A<B, if A>B then B=A+1 )
Param B (required A<B, if A>B then A=B-1 )
Param C
So I set kAudioUnitParameterFlag_IsGlobalMeta to Param A and B, and implemented
GetPropertySize() and GetProperty() to support
kAudioUnitProperty_DependentParameters.
In this situation, if I edited Param A, I expected Logic to notice
the change in Param B.
But Logic's Param B display was never changed. Still my plugin's GUI
changed correctly.
Actually, if I didn't support kAudioUnitProperty_DependentParameters, my plugin
works fine except one thing:
That is, If I recorded automation for Meta-flag parameter, then other unrelated
parameter's automation data was broken...
For example,
1. recorded Param C's automation
2. recorded Param A's automation
3. Param C's automation data was broken!!
This situation happens only on Intel-Mac. On PPC-Mac, It works well whether
kAudioUnitProperty_DependentParameters was supported or not.
So I suspect this is a bug of Logic(Intel).
Any help would be appreciated.
