USB bus-powered MIDI interface that delivers wide connectivity without extra power. Ideal for studios and live rigs that need reliable, visible MIDI routing and support for legacy Windows systems. Key benefits No external power required: connects via USB bus power for quick setup and fewer cables. High channel capacity: provides 16 MIDI input channels and 16 MIDI output channels to route multiple keyboards, controllers, sound modules, and sequencers. Clear status feedback: dedicated LEDs show MIDI In activity, MIDI Out activity, and overall MIDI signal status so you can verify connections at a glance. Simple compatibility: designed to work with Windows XP and Windows 7 systems for use with older DAWs and legacy setups. What it does and why you need it Centralizes MIDI connections so you can control many devices from a single computer without juggling separate adapters. Reduces setup complexity during rehearsals and live performances because it runs off the USB bus and gives visible confirmation of MIDI traffic. Supports larger hardware collections and multi-timbral routing tasks that require many simultaneous MIDI paths. Typical use scenarios Studio routing: Connect multiple hardware synths and drum machines to your DAW, managing MIDI routing for recording and multi-channel playback. Live performance: Consolidate controllers and sound modules into one USB-connected interface, monitor MIDI activity with LEDs, and avoid carrying extra power supplies. Education or shared rigs: Use with legacy Windows XP/7 workstations to teach MIDI routing or run older software that requires those operating systems.
