Setting up your system
8. If your audio hardware and its driver support ASIO
Direct Monitoring, you may want to activate the Direct
Monitoring checkbox on the page for the driver.
Read more about monitoring later in this chapter and in the chapter “Re-
cording” on page 74.
9. Click Apply and then OK to close the dialog.
If your hardware setup is based on an external clock
source
For proper audio playback and recording, it is essential
that you set the project’s sample rate to the sample rate of
the incoming clock signals. If you load a project with a
sample rate that is different from your clock source, the
program will try to change the settings of the clock
source, which may not be what you want.
By activating the “Externally Clocked” option, you “tell”
Cubase that it receives external clock signals and there-
fore derives its speed from that source. The program will
not try to change the hardware sample rate any longer.
The sample rate mismatch is accepted and playback will
therefore be faster or slower. For more information about
the Sample Rate setting, see
“The Project Setup dialog”
on page 44.
Ö When a sample rate mismatch occurs, the Record
Format field on the status line is highlighted in a different
color.
If you are using audio hardware with a DirectX driver
(Windows only)
Cubase comes with a driver called ASIO DirectX Full Du-
plex, available for selection on the ASIO Driver pop-up
menu (VST Audio System page).
Ö To take full advantage of DirectX Full Duplex, the audio
hardware must support WDM (Windows Driver Model) in
combination with DirectX version 8.1 or higher. In all other
cases, the audio inputs will be emulated by DirectX (see
the dialog help for the ASIO DirectX Full Duplex Setup di
-
alog for details about how this is reported).
Ö During the installation of Cubase, the latest DirectX
version will be installed on your computer.
When the ASIO DirectX Full Duplex driver is selected in
the Device Setup dialog, you can open the ASIO Control
Panel and adjust the following settings (for more details,
click the Help button in the control panel):
• Direct Sound Output and Input Ports
In the list on the left in the window, all available Direct Sound output and
input ports are listed. In many cases, there will be only one port in each
list. To activate or deactivate a port in the list, click the checkbox in the
left column. If the checkbox is ticked, the port is activated.
• You can edit the Buffer Size and Offset settings in this
list if necessary, by double-clicking on the value and typ-
ing in a new value.
In most cases, the default settings will work fine. Audio buffers are used
when audio data is transferred between Cubase and the audio card.
While larger buffers ensure that playback will occur without glitches, the
latency (the time between the moment Cubase sends out the data and
when it actually reaches the output) will be higher.
• Offset
If a constant offset is audible during playback of Audio and MIDI record-
ings, you can adjust the output or input latency time using this value.
Setting up the input and output ports
Once you have selected the driver and made the settings
as described above, you need to specify which inputs and
outputs will be used and name these:
1. In the Device Setup dialog, select your driver in the
Devices list on the left to display the driver settings for
your audio hardware.
All input and output ports on the audio hardware are listed.

A DirectX driver is the next best option to a specific
ASIO driver and the Generic Low Latency ASIO
driver.
