serial port. The advantage of this connec-
tion is that you retain a free Macintosh 
serial port. The disadvantage is that all 
MIDI and timecode communications 
occur over a single Macintosh port—you 
could get data overloads if you have a very 
dense MIDI data stream and are syncing 
to SMPTE timecode.

Two Networks
 
The second networking option involves 
placing one Studio 4 on each Macintosh 
serial port as shown in Figure 3.8. Set 
each Studio 4’s front panel 1-8/9-16 switch 
as indicated. With this connection, you 
can balance the MIDI data stream 
between the two Macintosh serial ports 
using the Network Routing window (dis-
cussed in Chapter 6). You cannot, 
however, use internal routings to send 
MIDI data from one box to another (as 
discussed in Chapter 7).

The final option is to use a single 2-cable 
network. This is similar to the one net-
work/1-cable configuration, except you 
connect a second cable between the last 
Studio 4's “A” port and the unused Macin-
tosh serial port as shown in Figure 3.9. 
Set each Studio 4’s front panel 1-8/9-16 
switch as indicated.
This configuration provides optimum flex-
ibility. You can balance the MIDI data 
stream (unlike the one network/1-cable 
connection) and you can use the 
Studio 4's internal routing to send MIDI 
data between interfaces (unlike the two 
network connection). Use the Studio 4's 
front panel THRU switches to access 
external peripherals.

Connecting Three Studio 4's to a 
Macintosh
 
You must use two networks if you wish to 
connect three Studio 4's to a Macintosh. 
One network contains two Studio 4's; the 
other network contains one. Set each 
Studio 4’s front panel 1-8/9-16 switch as 
indicated. Figure 3.10 shows a typical con-
nection involving three Studio 4's—with
