Right finally watched that.

Very interesting yes. I use a few vertical facing mics on organ so happy to hear that story.

Ordering more Schoeps...still not enough for giant 3d square (one day.)

One thing the prof hinted at was recording for unknown future formats. I suspect in not too long you will be able to sit in the best ever concert by your favourite band from history while at home.

Having material captured in a 3d format will help with this.
