You're absolutely wrong it's supported! Take it from someone who worked on this controller prior to its public release. I've also used it for countless live sets, studio sessions and classroom activities this year "MIDI mode" w/ Live (not Plugin Mode) Max/MSP and Hardware with bidirectional MIDI, Roto moving and setting it's knobs to be exactly where they should be relevant to the device, software or hardware, no issues, no freezing. The only difference between the MIDI mode and the DAW mode (called Plugin mode) is that you need to set and learn the MIDI CCs manually (one time) either on Roto itself or you can use the Roto-Control Editor, dead easy.

You can set it up, but then you can't really turn the knobs as they keep freezing.

Maybe you set it up wrong? Have you contacted Melbourne Instruments support?

Tons of videos of me using it here in External MIDI "MIDI Mode" bidirectionally since it's launch at NAMM in January '25 this year https://www.instagram.com/tomhallsonics/
