Using the internal sound generator
Specifying the function of the MIDI connectors
If the MIDI OUT/THRU switch on the rear panel is set to [IN1 THRU], MIDI messages received at the MIDI IN 1 connector will be retransmitted without change from the MIDI OUT 2 connector.
If the SD-80 is operating in USB mode and this switch is set to [IN1 THRU], MIDI messages received at the MIDI IN 1 connector will be "thru-ed" from the MIDI OUT 2 connector. The MIDI messages that would normally be output from the computer to the MIDI OUT 1 connector will no longer be output. (They will not be merged.) In this case, it will not be possible to use USB external output 2 (EDIROL SD-80 MIDI OUT 2) from the computer.
However, if the SD-80 is operating in MIDI mode and this switch is set to [IN1 THRU], MIDI messages received at the MIDI IN 1 connector will be "thru-ed" from the MIDI OUT 1 connector as well as being sent to PART A. In this case, if an external MIDI device sends a dump request to PART B, it will not be possible to transmit the response.
