Hi I just posted about this as well; no response yet but I could resolve two (well one and a half) of them on my own.
IM-Freezer gave me errors for supervp.scrub~ and sogs~. If you download the newest version of the SuperVP package here it has a working supervp.scrub~.mxo.
IM-Freezer is using an older supervp.scrub from 2021. To replace it you can open IM-Freezer’s max editor and unfreeze(snowflake button) the device; this will create an IM-Freezer Project folder in Documents/Max 8/Max for Live Devices/.
There in the externals folder you can replace the supervp.scrub~.mxo with the new one from the SuperVP package. If you save the device & use that one instead it should work.
This will at least allow you to use the ‘Main’/time-stretching & formant etc half of the device. The Contour/granular half uses sogs~ which I couldn’t find an updated version of.
The same process works for IM-Notetracker and the ~yin.mxo object, which you can find an updated version of in Somax 2.
I couldn’t find updated versions of any other objects that are showing errors so that’s as far as I got. So Chromax, both Modalys, Ianalyzer, the contour half of Freezer, and PsychHarmonizer like you said are still broken.
Sorry if that was excessive detail but I included it just in case anyone finds this who’s in the same boat as me as far as not really knowing sh*t about Max but desperately wanting to keep using Freezer since it’s one of my favorite devices (and also I paid $200 for it lol)
