Connecting to a Personal Computer
Connecting to an Apple Macintosh Series
Computer..............................................................
Connect the TO HOST connector of the P-120/P-120S to the
modem or printer port on your Macintosh, depending on which
port your MIDI software is using for MIDI data communication,
using a standard Macintosh 8-pin system peripheral cable. Set the
HOST SELECT switch to the “Mac” position.
You may also have to make other MIDI interface settings on
the computer side, depending on the type of software you use
(refer to your software owner’s manual). In any case the clock
speed should be set to 1 MHz.
● “Mac” Cable Connections
• 8-pin system peripheral cable.
• Data transfer rate: 31,250 bps.
Although the P-120/P-120S can be connected to a personal computer via the
MIDI IN/OUT connectors and a MIDI interface, the TO HOST connector and
HOST SELECT switch allow direct connection to Apple Macintosh or IBM-PC/AT
personal computers for sequencing and other music applications without the
need for a separate MIDI interface.
• When connecting the P-120/P-120S to a personal computer, first turn the power to both the P-120/P-120S and the com-
puter OFF before connecting the cable and setting the HOST SELECT switch. After connecting the cable and making the
appropriate HOST SELECT switch setting, turn the power to the computer on first, then turn on the P-120/P-120S.
• When not using the [TO HOST] terminal of the P-120/P-120S, make sure the cable is disconnected from the [TO HOST]
terminal. If the cable is left connected, the P-120/P-120S may not function properly.
•“ HS(” will appear in the display if the host computer is not turned on, the connecting cable is not properly connected, the
HOST SELECT switch is not in the proper position, or the MIDI driver or MIDI application is not active. In this case, turn
the power off on both the P-120/P-120S and the computer, and check the cable connection and the position of the HOST
SELECT switch. Once the connection and HOST SELECT switch position is verified, turn the power of the computer on
first, then the P-120/P-120S, to check if the MIDI driver and MIDI application function properly.
• When the HOST SELECT switch is set to “Mac”, “PC-1”, or “PC-2, no data transfer occurs via the MIDI connectors. To use
