Thanks Stephen for your answer.

On a new project, if I modify the render callback, I have this problem :
"ProcessPCH++ /Users/hervenoury/Library/Developer/Xcode/DerivedData/TestSynth41-dljjhorkvgwswccgysrorevqgtgb/Build/PrecompiledHeaders/TestSynth41-Prefix-ghhnhfecvrcwingvtzmbifpvqool/TestSynth41-Prefix.pch.pth TestSynth41/TestSynth41-Prefix.pch normal x86_64 c++ com.apple.compilers.llvm.clang.1_0.compiler
    cd "/Users/hervenoury/Documents/Mac et iPod/TestSynth41"
    (...)

clang: error: no such file or directory: '/Users/hervenoury/Documents/Mac et iPod/TestSynth41/TestSynth41/TestSynth41-Prefix.pch'
clang: error: no input files
Command /Developer/usr/bin/clang failed with exit code 1"

On an old project (a classic additive synth, correct with OSX 6) , I've got this problem :

on the line :

    int numChans = inBufferList.mNumberBuffers;    problem notified : "Member reference base "AudioBufferList**(aka 'AudioBufferList**) is not a structure or union
if (numChans > 2) return -1;

left = (float*)inBufferList.mBuffers[0].mData;  //same problem notification
right = numChans == 2 ? (float*)inBufferList.mBuffers[1].mData : 0;   //same problem notification
But AudioBufferList is not an union, it is a structure. It is not normal. 
Is there a complete information somewhere about all the modifications in the AU classes? 

Thanks again, please continue to help me, I knew to use AU after some mouths of experimentation before, I'd like to continue this work and not loose it.

Best regards,

Hervé Noury
