Networking Studio 4’s and
Standard MIDI Interfaces
You may network a Studio 4 with a stan-
dard MIDI interface. If you own an old
standard MIDI interface and have more
than 8 MIDI devices, the standard MIDI
interface will provide a few additional
MIDI ports. Figure 3.13 shows an exam-
ple of a Studio 4 networked with a
standard MIDI interface.
Figure 3.13: Standard MIDI Interface in a Studio 4
Network
Because your Studio 4 must be used at
1MHz when networked with a standard
MIDI interface and because MIDI routing
is not as flexible as with a network of two
Studio 4’s, you should consider this
arrangement only as a temporary “band
aid”. If you often need to access more
than 8 MIDI devices, you should seri-
ously consider purchasing an additional
Studio 4.
NOTE: You cannot network a self-powered
standard interface (such as a MIDI Trans-
lator) with the Studio 4.
If you use a dual port standard MIDI inter-
face, you can connect its second serial
port to the free Macintosh serial port to
access even more MIDI ports.
If your dual port standard MIDI interface
is a Studio 3, Opcode strongly recom-
mends that you connect the Studio 3
modem port to the Studio 4 “B” port, and
the Studio 3 printer port directly to the
Macintosh (as shown in Figure 3.14).
This is because the Studio 3 communi-
cates with the Macintosh only over its
printer port.
Figure 3.14: Studio 3 in a Studio 4 Network
Network connections involving a Studio 4
and a standard MIDI interface are rather
atypical. If you use this type of network in
your studio, you should first learn to use
the Studio 4 by itself. Only after you
understand the operations of the Studio 4
and OMS patches should you attempt this
network. For this reason, instructions for
working with these connections are dis-
cussed in Appendix B.
SMPTE CONNECTIONS
The Studio 4 has two SMPTE jacks on its
rear panel. The SMPTE IN jack is used to
receive a tape sync signal. The SMPTE
OUT jack sends SMPTE timecode as
specified in the Stripe SMPTE window
discussed in Chapter 10. If the Studio 4 is
receiving SMPTE at its SMPTE IN jack, it
