OVERVIEW

This chapter provides a brief overview of 
AudioDesk’s basic I/O and synchronization 
operation with the 896mk3 hardware. For 
complete information about all of AudioDesk’s 
powerful workstation features, see the AudioDesk 
manual included with your 896mk3 system.

SETTING UP YOUR SYSTEM

As described in chapter 4, “Installing the 896mk3 
Mac Software” (page 33), the AudioDesk and 
MOTU 896mk3 software installers will properly 
install and update everything for you.

If you are using a MIDI Timepiece AV or Digital 
Timepiece for synchronization, be sure they are 
present in Audio MIDI setup.

THE 896MK3 SETTINGS

Choose the 896mk3 as your audio input output 
device by choosing 

MOTU Audio System 

options>Configure Hardware Driver

 from the Setup 

menu. This window shows some of the 896mk3 
settings, such as sample rate and clock source, but 
to access all of the 896mk3 settings, open MOTU 
Audio Setup, as shown in Figure 5-1 on page 36.

Figure 8-1: Choose Setup menu> Configure Audio System> Configure
Hardware Driver to open the dialog shown above and access the
896mk3 CoreAudio driver. To access the rest of the 896mk3 settings,
open MOTU Audio Setup.

For complete details about the 896mk3 settings, see 
chapter 5, “MOTU Audio Setup” (page 35). The 
following sections provide a brief explanation of 
each 896mk3 setting for use with AudioDesk.
