Mark Of The Unicorn (MOTU) has announced a beta of its first Mac OS X product - a USB MIDI driver.
The driver makes all MOTU USB MIDI interfaces compatible with Mac software that supports standard OS X MIDI drivers.
Jim Cooper, MOTU marketing director, said: "This is a major leap forward in performance and interoperability for the entire Mac platform.
"With MIDI services integrated into the operating system, and a flexible driver model, OS X allows our USB MIDI interfaces to deliver sub-millisecond timing accuracy to all MIDI software under OS X."
A public beta of the OS X driver is available for free download.
