I have completed porting 7 of 11 of my previous Max externals to the Max7 format as 32/64 bit universal macOS externals. This is beta software, so if any of you would like to try them, I would enjoy feedback (error messages, crash reports) if they don’t work on your machine.
If you would like externals for earlier versions of Max – please check the freeware section of www.soundhack.com
