● MIDI data transfer with the computer
Depending on the setting of the computer switch, MIDI data flow will be different as
follows (with the factory settings).
❍ When the computer switch is set to PC-1, PC-2 or Mac
* In order for data received at MIDI IN A to be sent to the sound generator section, the Thru func-
tion of the computer software must be turned on. When thru function is turned on, the data
received at MIDI IN A will pass through the computer and be played by the sound generator sec-
tion. When transmitting MIDI Exclusive data from the sound generator section via this unit's
MIDI OUT/THRU connector, it is also necessary for thru function to be on.
* Data received at MIDI IN B will not be sent to the computer connector, but will be passed directly
to the sound generator section.
* The number of sound generator Parts that can be controlled using the computer connector will
depend on the software you are using. This means that if you are using the computer connector,
you will not necessarily be able to play 32 Parts. Carefully read the operating manual for your
software. Also be aware that although this unit allows two connectors MIDI IN A and B to be
used for 32 Part performance, this may impossible to achieve depending on your software.
