In your view you keep a reference to your AudioUnit (via the mAU
member variable). In your -setAU method you could call
AudioUnitGetProperty(mAU,
kAudioUnitCustomProperty_AssociatedDSPClassPointer,
													  kAudioUnitScope_Global,
													  0,
													  &mRefCon,
													  &dataSize);

to get the instance of your DSP class (in mRefCon), and cast this to
(myDSPClass*) in your code to use it to set your preset name.

In your DSP class you would have to implement this property (in
GetProperty and GetPropertyInfo) so it returns "this"
