Used to have the Maximal 3 CM that used to come with the older versions of Computer Music Magazine, they discontinued the magazine right after changing the plugins collection, and i lost the files of the old ones, is there someonne here who have it?

 

File Silo should have it. https://www.filesilo.co.uk/computermusic/

It was in Issue 309. https://www.filesilo.co.uk/computer-music-309/

 

Yeah, but i can't download, when i click on the button it just open another tab with the same page, I think the download servers are down...

 

I've seen these before. You get a link to a text file and inside it has the url to download it from the actual vendor of whatever software.
For this it is down or altered url, since they updated it to 3.0.x versions later on. You can put the original URL into the Archive.org Wayback machine. The server isn't down, but they may have removed the files from 6 years ago.

Is there some reason you are trying to get the CM free version of it, when there are full releases from R2R?
