3 Click GM Device in the left column of the Library tab, and you’ll see 16 entries in the
right column: 1 (Grand Piano), 2 (Polysynth), and so on.
4 Click the disclosure triangle to the left of the GM Device 1 entry in the Inspector (if the
Track parameter box is not already open). If the Inspector isn’t visible, click the
Inspector button in the Arrange Toolbar.
There are two parameters of particular note here: Port and Channel (see “ Setting
External MIDI Channel Parameters ” on page 254).
5 Click on All beside the Port parameter. You will see all of your MIDI interface Out ports
listed. As examples: Port 1 (Unitor 8), Port 2 (Unitor 8), MIDI1 (mLan Network). If you
choose a specific Port, say Port 1 (Unitor 8), the GM Device Multi Instrument object will
be routed to this specific MIDI port. This mirrors the port listing shown in the left
column of the Library tab.
