Networking Two Midi Timepieces; Installing A Midi Timepiece Network - MOTU MIDI Timepiece AV User Manual

To connect multiple MOTU interfaces to a
macintosh, you'll need an inexpensive device called
a USB Hub (purchased separately from your
computer peripherals dealer). A USB Hub has
multiple Type A ports on it, usually between 4 and
7 ports, to which you connect multiple USB MIDI
interfaces as shown in Figure 3-1. Connect them to
the hub in the standard fashion, as if you were
connecting them directly to the computer. If
needed, you can connect multiple hubs to each
other to get enough USB ports for your multiple
MOTU USB interfaces.

NETWORKING TWO MIDI TIMEPIECES

(For the MIDI Timepiece AV only)
The MIDI Timepiece AV-USB has a 'NET' serial
port that allows you to connect a second MIDI
Timepiece to it. The MIDI Timepiece AV-USB
then operates as 'Box 1-8' (MIDI ports 1 through
8), while the second MIDI Timepiece operates as
'Box 9-16'. The two networked MIDI Timepieces
then operate together as a single interface with 16
MIDI IN ports and 16 MIDI OUT ports. The two
interfaces also operate as a seamless MIDI
network, allowing to route MIDI data from any
MIDI input to any combination of outputs on
either interface. In the software, they appear as one
device with 16 MIDI INs/OUTs.
You can network any model of MIDI Timepiece to
a MIDI Timepiece AV-USB. Here is a complete list:

INSTALLING A MIDI TIMEPIECE NETWORK

(For the MIDI Timepiece AV only)
To network a second MIDI Timepiece to a MIDI
Timepiece AV-USB:
1 Connect the MIDI Timepiece AV-USB to your
computer via USB in the standard fashion, as
described in the previous chapter (or to a USB hub
as described in this chapter).
2 Connect the second MIDI Timepiece to the
'NET' serial port on the MTP AV-USB using a
standard AppleTalk serial cable (included with
your older model MIDI Timepiece or purchased
separately) as shown below in Figure 3-2.

Timepiece AV-USB via their network serial ports. The second MIDI
Timepiece can be an MTP AV, MTP I, MTP II or even another
MTP AV-USB. The Mac serial port on Box 9-16 can be optionally
connected to a serial port on a second Macintosh.
Please note: never try to connect three
MTP AV's directly to one another!
