The UM-ONE mk2 from Roland is a compact 16-channel MIDI interface. The in-line cable form factor provides a single MIDI output and a single MIDI output connector on one side, and a USB cable on the other with a Type A USB connector.
The USB bus powered interface includes high-performance FPT processing for low latency and tighter clock timing. Compatible with Mac and PC computers, and iOS for the Apple iPad (requires optional Apple iPad Camera Connection Kit), the super compact interface is affordable, reliable, and easy-to-use.
