SonicBirth, the Mac OS X Audio Unit / VST designing application that allows users to build their own Audio Unit / VST plugins, either by working with existing circuits or by creating circuits completely from scratch, has been updated to version v1.2.0 and released as freeware and open-source (GPL) (available on SourceForge).
SonicBirth is now free and open-source.
Fixed a problem for VST state saving/restoring.
