Big Tick Audio has updated Zen, the free Universal Presets Manager, to version 1.1. This update fixes a lot of the crashes and annoyances found in version 1.0 (and hopefully, doesn't introduce too many new ones). Update 1.2 will add more features.
The big news for this version is that it is now available for Mac OS X.
Zen is a Universal Presets Manager: It loads in any host as a VST instrument, and acts as a loader for other VSTis. So with Zen, you can search for "Rhodes piano" and get a list of all matching presets – regardless of the final VSTi (Rhino, Zebra, Absynth... whatever). When you select one of the presets in Zen, the corresponding VSTi is automatically loaded to play the requested preset.
