Fig. 1.5: USB mode with MIDI THRU

In this mode, the keyboard messages are sent to the computer via USB.

The messages from the computer are transmitted to the UMA25S (data reception) and simultaneously to all MIDI units which are connected to MIDI OUT. This mode is ideal for playing the keyboard and controlling further MIDI hardware (samplers, rack synthesizers, etc.) with the sequencer.
