MOTU today announced it is now shipping (DP4) for Mac OS X. DP4 includes a previously unannounced Freeze Tracks feature that allows users to temporarily "print" audio tracks and virtual instrument tracks to disk to free up additional computer processing resources. "Initial DP4 orders shipped to the retail channel on our announced target date of April 2nd, 2003. Since then, manufacturing has steadily ramped up to fulfill thousands of upgrade orders." As a "Mach-O" app, DP4 takes full advantage of Mac OS X's built-in MIDI and audio services, delivering CoreMIDI XML MIDI instrument patch lists, support for CoreAudio, multiple CoreAudio driver support, device remapping, and interapplication MIDI. DP4 carries forward hundreds of patch lists from previous versions and publishes them for any Mac OS X application that supports this new Mac OS X standard. Upgrades are $150 plus shipping & handling.
