I have seen Gene's solution from the AU MIDI processor tutorial (thanks, BTW!), which is to duplicate a bit of the code from allocateRenderResourcesAndReturnError() to capture an instance property. Was this your workaround as well? If the render block and its captures are being fetched before what is ostensibly the render initialization for the AU, then should we force call it, or just put any init in internalRenderBlock and ignore allocateRenderResourcesAndReturnError altogether?
