2. Transmitted Data (Media Player Section)
2.1 Messages transmitted during performance
When the UDMR's MIDI OUT setting is configured to 'OUT', a memorized MIDI message is
transmitted when a MIDI phrase (i.e. a standard MIDI file stored on a CF card which has been
formatted on the UDMR) is performed.
In this case, the received message is not transmitted (THRU).
2.2 Transmission of received messages
When the UDMR's MIDI OUT setting is configured to 'THRU', received messages are
transmitted.
2.3 Transmission of generated messages
When the UDMR's MIDI OUT setting is configured to 'THRU', the following generated
messages are transmitted.
