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.

here is the recorded audio as wav

What you experience is simply the change between the individual positional impulse responses. Dependent on the position of the Icon on a MIR Venue's stage (or more precisely: dependent on the position of its Width-handles) the closest set of IRs is chosen and prepared for convolution according to the chosen Instrument Profile and Output Format.

You have assigned the High-Directivity General Purpose profile, which is not very suitable for a broad ensemble like that men's choir you were using in the audio demo, that's why the effect seems to be exaggerated. Try a Wide Cardioid or even Omni profile instead.

I was able to pass my ASIO output through and created this video explaining the issue.

As described, the sound jumps on a certain radial distance on the decca tree. The change in sound is quite drastic.

Thanks for the video.

To rule out any unknown variables, please try the same test with a tried-and-tested "classic" Output Format like an M/S with a cardioid center capsule. Also, use a simple general purpose profile such as an Omni or a Cardioid for the sound dispersion of the source. Finally make sure that all the options for Dry Signal Handling are switched off. Let's take it from there, then.

... you might very well have fallen into the traps of Higher Order Ambisonics when trying to create an array of virtual capsules that resembles a Decca Tree visually, although it has very little in common with it physically. :-)
