MIDI 8•9
THE COMPUTER PORT
You can use the COMPUTER port via a single
cable instead of the MIDI IN and MIDI OUT ports.
The COMPUTER port only handles the MIDI
channels of group A (A1...A16).
Apple Macintosh
The Macintosh (or compatible) must communi-
cate at the velocity of 1 MHz.. Consult the manual
of the sequencer for information.
Use a standard Macintosh serial cable. Connect
one end of the cable to the WK4 and the other to
the MODEM port of the Macintosh.
IBM PC
The IBM-PC (or compatible) can communicate
at the velocity of 31250 baud (PC1) or 38400
baud (PC2).
Use standard Serial cables. Insert the small con-
nector (DB9) to the WK4 COMPUTER port and
the larger connector (DP25) to the RS-232 port
of the computer.

WK4
-COMPUTER-EXPANDER CONNEC-
TION
Connect the WK4 to the computer in the follow-
ing manner (closed loop):
• WK4 MIDI OUT connected to the computer’s
MIDI IN.
• WK4 MIDI IN connected to the computer’s
MIDI OUT.
Connect one of two expanders to the WK4 MIDI
THRU ports. These ports transmit exactly the
same data as those received at MIDI IN:
• MIDI THRU A retransmits data received at
MIDI IN A.
• MIDI THRU B retransmits data received at
MIDI IN B.
Connect the expander’s MIDI IN to one of the
MIDI THRU ports.
Mute the WK4 tracks that are assigned the MIDI
channels dedicated to the expander.
