For the connection cable, use the appropriate cable below (sold separately) that matches the per-
sonal computer type.
● IBM-PC/AT Series
Connect the RS-232C terminal on the computer to the TO
HOST terminal on the 9000Pro using a serial cable (D-SUB
9P -> MINI DIN 8P cross cable). Set the 9000Pro 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 9000Pro
using a serial cable (system peripheral cable, 8 bit). Set the
9000Pro 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 soft-
ware 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 9000Pro. 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
9000Pro 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 174) on the 9000Pro as
described below, and make the appropriate port settings on your computer/sequencer software.
