INTRODUCTION
U2MIDI Pro is a professional USB MIDI interface that provides

Kit) and Android tablets or phones (via Android OTG cable).
The device comes with 1x MIDI IN and 1x MIDI OUT via
standard 5-pin MIDI ports. It supports 16 MIDI channels, and is
powered by a standard USB bus.

with fast transfer rates via USB. This enables the throughput of large
data MIDI messages, achieves the best latency and accuracy on

(developed by CME), you enable flexible routing and filter settings for
this interface. All settings will be automatically saved in the interface.

sockets, such as: synthesizers, MIDI controllers, MIDI interfaces,
keytars, electric wind instruments, v-accordions, electronic drums,
electric pianos, electronic portable keyboards, audio interfaces,
