There's now also the "TOA Harpex" VST plugin, which upsamples from first order B-Format to full 3D 16-channel TOA. > > 7. I was planning on recording listening situations using a TetraMic.

You'd need "Rapture3D Advanced" for a non-standard/irregular speaker layout - "TOA Decoding" targets standard layouts only. Alternatively, the Rapture3D Player can be used for stand-alone TOA playback. Currently you can't use iTunes to play ambisonics directly AFAIK.
