Can't do 32 oscillators since there are 30 max generators, and you need at least 1 output generator so in theory 29 FMing. However, you need to use groups to sequester the modulators depending on what kind of algorithm/routing you are using.

And if you want the patch to fry your CPU, have at it: https://www36.zippyshare.com/v/xiOJ4Pie/file.html
