MIDI I/O ON WINDOWS

On Windows, the MOTU AVB installer provides a
USB MIDI driver for the Stage-B16. This driver
allows you to access the Stage-B16's MIDI input
and output ports through its USB connection to
the computer. The ports are published in Windows
and are available to all MIDI software.

MIDI I/O SETUP ON THE MAC

Core MIDI is the "under-the-hood" component of
Mac OS X that handles MIDI services for MIDI
hardware and software. Core MIDI provides many
universal MIDI system management features,
including MIDI communication between your
Stage-B16 interface and all Core MIDI compatible
software.
Audio MIDI Setup is a utility included with
Mac OS X that allows you to configure your
Stage-B16 interface for use with all Core MIDI
compatible applications. Audio MIDI Setup
provides:
A "virtual" studio on your Mac that graphically
■
represents your MIDI hardware setup and that is
shared by all Core MIDI-compatible programs
A simple, intuitive list of your MIDI devices
■
whenever you need it in any Core MIDI-
compatible program
Launching Audio MIDI Setup
1 Make sure your Stage-B16 interface is
connected (a USB connection is required) and
turned on.
2 Launch the Audio MIDI Setup utility.
This can usually be found in /Applications/
Utilities. If it has been moved, just search for Audio
MIDI Setup.

3 Confirm that the MIDI interface is present in the
MIDI Devices tab (or window) in Audio MIDI
Setup. If the interface does not appear, or if it is
grayed out, check your cable connections and click
Rescan MIDI.
Connecting MIDI devices to the Stage-B16
Once your Stage-B16 interface appears in Audio
MIDI Setup, you are ready to add devices, indicate
how they are connected, and identify properties
they may have for particular purposes. This
information is shared with all Core MIDI
compatible applications.
To add a device in Audio MIDI Setup:
1 Click Add Device.
2 Drag on its input and output arrows to draw
connections to the Stage-B16 that match its
physical connection.
Figure 3-3: Connecting devices to the Stage-B16. In this example, a
controller keyboard is connected to the Stage-B16's MIDI IN, and a
sound module is connected to the Stage-B16 MIDI OUT.
3 Double-click the device to make settings, such
as input and output channels, that further describe
the device.
