Just letting everyone know that I've released a patch extension library for Automat softsynth available for Mac OS X, called Automatik. Automat itself is free and the library is also the most low-cost we've ever released, so it's a cheap but nice way to get new non-static sounds for your Mac.
So far it includes 72 patches with more planned soon as always. You can visit the Automatik info page for demos and manual.
All the best,
Artemiy.
