There are unfriendly versions that are FOC, but just that you have to make do with some limitations. E.g. Pro Tools Lite for Mac and Win XP, downloadable from the Digidesign site itself. Or some friendly programmers who write some stuff and share them, like some midi drum machines some years ago, can't remember.
What I'm trying to say is, yeah there are free stuff, just have to make do a bit. But I haven't checked things out in recent years, wonder if such free things still exist for downloads...
