Motor Mix not functioning anymore in PT 2021.3.1

[DualCoreX2]

I have been very lucky with the CM Motor mix working in every single Pro Tools release I've installed.

After installing PT 2021 all I see is on the Motor Mix LCD screen is "Motor Mix (tm) is ready for a session" and I see that the motorized faders do mimic what's the on the mixer but it's impossible to use in this state.

I think that the Motor Mix uses the HUI protocol so I was disappointed that it just stopped working in PT 2021.3.1

Is there anyone in the forum who still successfully uses the Motor Mix with Pro Tools 2021.3.1 running with Big Sur 11.2.3? I know it's not supported anymore, but I'm hoping there's a workaround.

Thanks in advance,

fyi, HUI with Pro Tools 2021.3.1 Mojave works fine.

Try to turn on Rosetta2 for any Moto drivers (?)
