Hello Jörn, brilliant, thanks so much for your answer. As far as I understand the Tetramic has TA3 and TA6 connectors (AKA mimi XLR) which I use on a daily basis with my SD552 and 788T with no problem. What is the problem you encoutered with them? Also they claim to sound as good as a DPA mic,

David, I've also got an ambisonic visualizer plugin developed but not published . Aside from the kind of interface cleanup it would need for public release, it uses what I eventually realized is a horribly inefficient algorithm. I've mostly built it for my own testing purposes - to see what
