Using the internal sound generator
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
fig.7-2
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.
