Back in the day, before M-Audio was M-Audio, everybody and their dog had a Midiman MIDISPORT 4x4 USB-MIDI I/O. Seriously, these things were everywhere. Know why? It's because Midiman built their super-reliable MIDI interfaces out of metal. That's right - no cheap plastic housing to get crushed under the weight of your gear, we're talking solid metal. The only problem was that they were a spleen-wrenching shade of off-seasick green that nobody could stand. Well, M-Audio didn't get where they are today without evolving and changing based on the needs of their customers, and that's why they reissued the classic MIDISPORT 4x4 Anniversary Edition in tasteful black. Now you the same great plug-and-play, 4-in/4-out MIDI interface with the hard-wired THRU switch that generations of sequencing cats have counted on for years and years, but in a tasteful color that matches your gear.
