I notice it in the Vienna Synchron Stage A:
See the mic position in the screenshot. When you move it to top/bottom just a little bit, the sound radically changes as if the calculation has a threshold here.
I did a record if the movement back to front , then left front to back, then to the right....always moving over this distance mark where the jump occurs. It occurs to me that a similar instrument is sounding differently when placed before or beyond this mark.
