Audio-solutions developer Mark of The Unicorn (MOTU) joined the extensive roster of company's showing support for Mac OS X at US music event NAMM yesterday.

The company demonstrated Digital Performer for Mac OS X at the show. Digital Performer is a modern audio-production environment that features universal MIDI and audio compatibility using OS X's CoreMIDI and CoreAudio services.

The company also announced its support for Apple's Audio Units plug-in architecture at the show.

MOTU's marketing manager Jim Cooper said: "We've taken full advantage of OS X's modern architecture. We believe that Digital Performer for X sets a new standard for desktop music and Audio."

The company has harnessed Apple's technologies to add universal compatibility to its products. Because of its support for Apple's audio technologies, Digital performer users will enjoy plug-&-play compatibility with third-party audio and MIDI hardware, software, plug-ins, virtual instruments and other products.

MOTU demonstrated Apple's Audio MIDI Setup utility at the show. This offers OS X users system-wide MIDI-device management. For example, MOTU MIDI interfaces immediately appear in the Audio MIDI Setup window when they are plugged into the Mac's USB port. Users can make MIDI device connections and settings with photo-realistic icons of hardware devices.

MOTU also announced that it is converting its entire patch-list library - including sounds from hundreds of current and vintage synthesizers and other instruments - to OS X to ensure Digital Performer users can move to OS X with minimum disruption. All OS X MIDI applications can use MOTU's patch lists as well.

Finally, the company demonstrated some new features and enhancements in Digital Performer for OS X. Rewire 2.0 support gives Digital Performer users full MIDI and audio I/O compatibility with Propellerhead Reason and other Rewire-compatible virtual instruments. Numerous enhancements have been added to Digital Performer's QuickScribe notation window, including score arrangement features, such as repeat bar-lines, endings, codas, and others.
