Rare and excellent midi interface. One of the best that have been released.

The MT4 is a small Half-Rack MIDI Interface with 2 MIDI in and 4 MIDI out and USB connection. It supports PC and MAC platforms and has drivers for most operating systems. The MT4 can also be used as a MIDI PATCHBAY. In general, the MT4 is a reliable USB MIDI Interface that works with all software on the market and its installation is so simple that it can be done by even the least experienced user. Finally, the small size and minimal weight make the MT4 an ideal MIDI Interface for any ''portable application'', and therefore for any notebook used in conjunction with music programs.
