micro express is a 4-in/6-out MIDI interface with SMPTE synchronization. THE MICRO EXPRESS NOW INCLUDES: Support for 23.976 time code* Update ClockWorks software Built with MOTU’s award-winning MIDI interface technology, the micro express is a compact, bus-powered MIDI interface and time code synchronizer that provides expandable, plug-and-play connectivity to any USB-equipped Mac or Windows computer. It's an Express XT — but compact and portable The micro express is a mini version of the MIDI Express XT. It has many of the same features as the Express XT — except that it is smaller, bus-powered, and even more affordable. The micro express provides 4 MIDI inputs, 6 MIDI outputs, 96 MIDI channels and compatibility with all Mac and Windows software. Sixteen convenient, one-touch presets (8 factory and 8 user programmable) give you instant front-panel access to multiple operational configurations. The included ClockWorks™ console software for Mac OS X and Windows 7/Vista provides comprehensive MIDI routing, merging and muting. Professional time code sync As a professional-grade SMPTE time code synchronizer, the micro express converts and stripes time code in all frame formats (23.976*, 24, 25, 29.97 drop and non-drop, and 30). SMPTE “jam sync” with adjustable freewheeling provides glitch-free sync. The micro express also supports MIDI Machine Control (MMC), with the ability to serve as either an MMC master or slave. The micro express can distribute MMC transport commands to all other connected MMC devices. Foot switch support Connect a foot switch to the convenient front-panel pedal input and then program it to generate MIDI data when pressed. Send the data to any connected devices. For example, you could send MIDI patch changes to synths and sound modules during live performance. Expandable, plug-and-play bus-powered USB operation The micro express takes full advantage of USB, giving you high-speed MIDI throughput, sub-millisecond timing accuracy, support for “hot-swapping” and plug-and-play expansion. Need to connect another sound module or synth? No problem. Just add another MOTU USB MIDI interface via any available USB port. Because it's bus--powered, you can take the micro express anywhere. No other MIDI interface offers this much value and performance at such an affordable price. *This feature is available only in micro express "re-release" models manufactured in 2011 or later.
