MHC Synthesizers and Effects has announced that version 1.5.3 of Extreme for Mac OS X has been released.
Extreme v1.5.3 has got the same changes as MHC recently implemented for Ambient Keys and Industrial Tones. It includes fixes for Snow Leopard and Logic 9 and MHC has moved to an Intel-only codebase with optimizations for Intel processors (Power PC isn't supported any longer). In addition, all soundpacks that used to be optional are now included.
The plug-in has been tested on Snow Leopard and Logic 9 (plus a few more hosts and, of course, Apple's Audio Unit validation tool). The new version also includes the three soundpacks which used to be optional. Version 1.5.3 for Mac OS X requires Snow Leopard and an Intel Mac.
Users who own a previous version can upgrade to the new version for $99 by contacting MHC Synthesizers and Effects here.
Extreme now costs $299.
