This post is for the Mac users.
When it comes to Mac OS X, the number of freeware plugins is very low, compared to the Windows world.
The popular “Save as VST” softwares (Synthedit and Synthmaker) are Windows only.
The “upgrade” politic of Apple is a sort of nightmare for developers (and sometimes users!), so many old free plugins don’t work anymore…

it’s AU only and should work with your favorite Mac host software.
