Working with Host Audio Software
OVERVIEW
Your MOTU interface provides multi-channel
audio input and output for Core Audio compatible
audio applications on the Mac and ASIO or Wave
compatible applications on Windows, including
MOTU’s Digital Performer and AudioDesk,
Apple’s Logic Pro and GarageBand, and other
third-party software applications such as Ableton
Live, Avid Pro Tools, Cockos Reaper, Propellerhead
Reason and Record, Steinberg Cubase and
Nuendo, Cakewalk SONAR, PreSonus Studio One,
Bitwig, and others.
AudioDesk is available as a free download for 24Ai
and 24Ao owners at motu.com/avb. For complete
information about all of AudioDesk’s powerful
workstation features, refer to the
AudioDesk User
Guide.pdf included in the AudioDesk application.
Digital Performer, MOTU’s state-of-the-art digital
audio workstation software, is available separately;
for details about upgrading from AudioDesk to
Digital Performer, talk to your authorized MOTU
dealer or visit motu.com.

PREPARATION
Install your host audio software first if you haven’t
already done so, and complete these chapters
before proceeding:
■
chapter 3, “Software Installation” (page 29)
■
chapter 4, “Hardware Installation” (page 33)
RUN THE WEB APP
Before you run your host audio software, launch
the web app to configure your MOTU hardware.
The web app lets you configure important settings
in your audio interface, enable the desired inputs
and outputs, and set up audio streams to and from
the computer.
Sample rate
Choose the desired sample rate for your interface
and your host audio software. Newly recorded
audio will have this sample rate.
Clock Mode
This setting is important because it determines the
master digital audio clock for your system.
If you do not have any digital audio connections to
your MOTU device (you are using the analog
inputs and outputs only), and you will not be
resolving your host software to word clock or
another external clock source, choose
Internal .
If you have devices connected to the optical ports,
see “Syncing optical devices” on page 41.
If you are slaving your MOTU device and your host
software to word clock, follow the directions in
“Syncing word clock devices” on page 41.
Enabling and disabling input/output banks
In the web app Device tab (page 15), enable all
input and output banks on your MOTU device that
you wish to make available to your host audio
software. Disable banks you are not using to
simplify operation.
