Fairlight Ambisonic Mapping

I have a custom 16 speaker configuration for an art installation that surrounds the room both on the level and above and below the audience. DR19's new Ambisonic mixing feature seems like a good way to test this. Anyone know how to map my custom arrangement into Fairlight so I can mix to this? The DR19 Reference Manual pages between 3700-3800 cover all manner of interesting info on what is possible, but seem very thin on how to actually do anything.

I think(?) what I am talking about is in the "B-Chain Monitoring" section of the manual (p.3857) I'll start working my way through this but if anyone has been down this road, please jump in.

Okay that's not quite what I was looking for.

It seems like the process uses an ambisonic microphone that you place in the center of a custom speaker space and run a test pattern sound through all of the speakers one-by-one to record a "profile" of the location of the speakers. The profile data is then fed into the decoder to let it know where the speakers are in space.

I am looking for how to feed that data into DaVinci Fairlight.

What is the source format? Is the input an impulse response?

Let's keep it simple. Lets say I have a mono sound of a hummingbird and I want to pan the sound around my room of 20 speakers.

Resolve supports up to 5th order which requires 36 channels. 4th order requires 25 channels.

What is the required monitoring configuration? Resolve does not currently allow custom configurations and only Preset formats are available.
