Apogee Electronics has introduced the Symphony 64 ($995)—a 64 channel, 24-bit, 192 kHz PCI Express card designed to interface X-Series and Rosetta Series converters directly to Apple Mac Pros.

The Symphony 64 features extended audio routing with VBus and SBus technology. VBus allows you to route standalone software instruments between Core Audio-based applications, instead of running them as plug-ins. Symphony''s SBus, on the other hand, doubles the DSP power of the Symphony System by facilitating, with a single cable, the communication of digital audio between Symphony-equipped Macs. This technology lets you route audio to a second computer and back again for plug-in processing, sample libraries, soft-synth players, and session transfers from one Core Audio application to another.

The system also offers up to 128 channels of I/O per Mac Pro, near zero latency performance, Apogee''s Maestro software for advanced control and routing, and compatibility with any Core Audio application.

Those of you who purchased a Symphony 32 card 60 days before October 3, 2008 may upgrade to the Symphony 64 card for $295, through Apogee.
