GRM tools GUI lag in max on M1 macbook Pro Max

[ C W M ]'s icon

Anyone know how to fix glitchy AU/VST interface for GRM tools in Max? I have the latest GRM tools and they are M1 optimized, but something in Max seems to not like them. They work fine in Ableton live 11 and in Reaper. But the GUI lags and pauses inside of Max. so weird.

thanks for any help!

Just did a quick test.
Try the VST versions (they work generally a little better).
Here on Mac mini M1 with GRM Doppler:
AU – Unusable lag with mouse, agitation works.
VST – Seems to work well. If you are in stereo, you have to choose "GRM Doppler Stereo".
VST3 – Does not work.
