Using the TO HOST terminal
Connect the serial port of the personal computer (RS-232C terminal or RS-422 termi-
nal) to the TO HOST terminal of the PSR-9000.
For the connection cable, use the appropriate cable below (sold separately) that
matches the personal computer type.
IBM-PC/AT Series
Connect the RS-232C terminal on the computer to the TO HOST terminal on the PSR-9000
using a serial cable (D-SUB 9P -> MINI DIN 8P cross cable). Set the PSR-9000 HOST
SELECT switch to the "PC-2" position.
Macintosh Series
Connect the RS-422 terminal (modem or printer terminal) on the computer to the TO HOST
terminal on the PSR-9000 using a serial cable (system peripheral cable, 8 bit). Set the PSR-
9000 HOST SELECT switch to the "Mac" position.
Set the MIDI interface clock in the sequencer software you are using to 1 MHz.
For details, carefully read the owner's manual for the software you are using.
For details about the necessary MIDI settings for computer and sequence software you are
using, refer to the relevant owner's manuals.
About the Thru Port Function
This function can be used when a computer is connected to the TO
HOST terminal of the PSR-9000. It gives you exceptionally flexible and
comprehensive control over the routing of incoming MIDI data.
For example, you could use this to selectively play back parts of song
data from a computer — having the PSR-9000 respond to certain parts
of the song, while playing back other parts on a separate connected tone
generator (as shown in the illustration).
Select the desired THRU PORT settings from the MIDI SYSTEM display
(page 150) on the PSR-9000 as described below, and make the appro-
priate port settings on your computer/sequencer software.
THRU PORT
NO THRU All incoming MIDI data from the computer is recognized by the PSR-9000, but
is not transmitted through the MIDI B OUT terminal.
THRU All incoming MIDI data from the computer is recognized by the PSR-9000 and
is also transmitted unprocessed through the MIDI B OUT terminal. In this case,
the MIDI B OUT terminal functions as MIDI THRU.
OFF Only MIDI data assigned to Port 1 from the computer is recognized by the PSR-
9000. The data is not transmitted through the MIDI B OUT terminal. Any MIDI
data that is assigned to ports other than Port 1 is not recognized or transmitted.
1-8 Only MIDI data assigned to Port 1 from the computer is recognized by the PSR-
9000.
The data that is assigned to the port number set here is transmitted through the
MIDI B OUT terminal. Any MIDI data that is assigned to ports other than the one
selected here and Port 1 is not recognized or transmitted.
