Using the internal sound generator
Specifying the function of the MIDI connectors
The SD-80 has two modes in which MIDI data is transferred differently: USB mode and MIDI mode. The mode is switched automatically depending on the connector you use.
■USB mode
MIDI messages received at the MIDI IN connectors will not be passed directly to the internal sound generator. They will be sent via USB to the computer (sequencer software).
This means that if you have started up in USB mode, playing an external MIDI keyboard connected to a MIDI IN connector will not play the SD-80’s internal sound generator. In order for the MIDI messages received at the MIDI IN connectors to be passed to the internal sound generator, you must turn on the Thru function of your software running on your USB-connected computer. “Thru” is a function by which MIDI messages received from the SD-80’s USB connector are retransmitted back to the SD-80’s USB connector. If the Thru function is turned on, the MIDI messages received at the MIDI IN connectors will pass through the computer and be passed to the SD-80’s internal sound generator, causing sound to be produced.
*The number of internal sound generator parts that can be controlled from the USB connector will depend on the capabilities of your sequencer software. This means that even if you connect the SD-80 to your computer via USB, you will not necessarily be able to use all 32 parts. Please carefully read the owner’s manual for your sequencer software.
*The USB indicator will light.
