@sommerdi Hi! Thank you for your feedback - really useful! I have the IEM plugins, I will experiment.
With my Focusrite Soundcard set to 96KHz and Isadora set to 96KHz with a 128-sample audio buffer I get the least delay - it's very slight, but annoying.

However, when I try this in Reaper with the same audio settings and audio interface the sound is crystal:

Hopefully I'll report back with a solution - possibly the IEM plugin suite.
P.S. The Sennheiser AMBEO plugin seen above is discontinued (Isadora doesn't recognise it) and has been superseded I believe with the dearVR plugin that I'm using in Isadora.

there is an other interisting free VST3 plugin suit for ambisonic ...
I have discovered that the issue is with Mac OS and that this is a common problem with touchscreen overlay devices using a Mac.
I have found this utility on Github that identifies and attempts to fix the issue:

yes the last patch , as i would do .... but put the plugin vst dearVR Pro2 behind ....
maybe the vst plugin has a high latency .... this real pain ...
@sommerdi Thank you for your advice. I've set each of the four preamp channels on the Focusrite so that they match.
Frustratingly I'm getting some weird delay effect - even though the audio interface is set to "direct monitoring" and I've set Isadora's audio buffer to 128.
Do you mean the signal flow should be like this:

Thanks again!
Good idea to do this live in IZZY ... i transfer this into max/msp with spat5 for movment.
in the case you are running all input driver in the scarlet on 100% on the same level, then you will have the A-Format. I am recording with the Zoom F6 in A Format
So i my eye you need only one vst plugin to convert in a B-Format ... i going to test this with the F6 ... and output in an Motu ...
@dbini Thank you! This is encouraging. I'll take a look at the Dirty Deal Audio website and their resources.
Best wishes

I haven't tried ambisonics in Izzy yet, but had a discussion with a colleague and we decided that it is properly possible. We took part in a residency project in a 19-speaker dome studio in Latvia last year. Dirty Deal Audio organised the project, and it's likely that they will be running more residencies: https://www.dda.lv/
Getting experience in a studio that is designed for ambisonics would be a huge help on your journey. The DDA website also has various resources, including tutorials using Sonobus, which should be applicable to the VSTs running in Isadora.
Hey!
I am also currently in a middle of a campaign, but can give you some files tomorrow afternoon(ish) if I am back in the studio
