The MIDISport 4x4 USB Anniversary Edition from M-Audio is a 4 input, 4 output MIDI interface that can handle 64 discrete channels of MIDI I/O. Powered from the USB bus of the host computer, the unit is extremely portable and is compatible with both the Mac and Windows platforms.
The interface allows for multiple sound units to be interfaced with a computer and each input and output port has an LED indicator displaying MIDI activity. Due its design, the MIDISport 4x4 USB is an excellent choice for both a professional or project studio, as well as for portable use.
The Anniversary Edition celebrates M-Audio's 20th anniversary with an updated new look without changing the original MIDISport 4x4 functions.
