The MTP AV is an 8-In 8-Out MIDI merger and router, a central hub for SMTPE & MTC timecode generation, and a computer MIDI interface compatible with the Mac & PC. You can merge any combinations of the eight inputs simultaneously to any combination of the eight outputs. Because the MTP AV's internal memory can be programmed from the front panel,the MTP AV is the perfect choice for live performance applications where fast and flexible MIDI patching is essential. You can take the MTP AV on the road because it can operate with or without a computer. The MTP AV can be set to change scenes in response to patch changes, allowing remote control from any MIDI controller.
