Emagic announces the MIDI Transmitter Four, MT4, USB MIDI interface for both Mac and Windows. This two in, four out USB-only MIDI interface addresses the need for a low cost USB interface solution. The release of the MT4 solidifies Emagic's complete cross-platform product line and further exemplifies Emagic's commitment to provide high quality solutions at every possible price point. 

Emagic's MT4 is a stand-alone two in, four out USB MIDI interface for both Mac and Windows 98. Powered by USB, the MT4 has a practical design, featuring compact size in a light-weight non-slip casing. All inputs and outputs are independently addressable for a maximum of 32 channel inputs and 64 channel outputs. The MT4 has two MIDI In activity LEDs and four MIDI Out activity LEDs, and has a programmable Patch Mode that allows for stand-alone use as a MIDI patchbay. Using the included software, up to 32 patch configurations can be stored and are switchable via MIDI program change. Patch Mode is indicated by its own LED, as is USB activity. The MT4 is directly supported in the Logic Audio Mac series and can also be addressed via OMS. On Windows it is addressed via USB MME drivers.
