Setting up your system
If you are using audio hardware with a DirectX driver
(Windows only)
Nuendo 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 be able to take full advantage of DirectX Full Du-
plex, 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 dialog for details
about how this is reported).
Ö During the installation of Nuendo, the latest DirectX
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 to 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 Nuendo and the audio card.
While larger buffers ensure that playback will occur without glitches, the
latency (the time between the moment Nuendo 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 should be used and name these:
1. In the Device Setup dialog, select your driver in the De-
vices list on the left to display the Driver settings for your
audio hardware.
All input and output ports on the audio hardware are listed.
2. To hide a port, click in the “Visible” column for the port
(deselecting the checkbox).
Ports that aren’t visible cannot be selected in the VST Connections win-
dow where you set up your input and output busses – see “Setting up
the VST Connections” on page 26 and the chapter “VST Connections:
setting up input and output busses” in the Operation Manual.
3. To rename a port, click on its name in the “Show as”
column and type in a new name.
Ö It is a good idea to give your ports names that are re-
lated to the channel configuration (rather than to the ac-
tual hardware model)!
For example, if you are using a 5.1 surround audio setup, you could name
the six ports Left, Right, Center, Lfe, Left Surround and Right Surround.
This makes it easier to transfer your projects between different comput-
ers, e.g. in different studios – if the same port names are used on both
computers, Nuendo will automatically handle the bus connections prop-
erly when you open the project on the other computer.
4. Click OK to close the Device Setup dialog and apply
your changes.
If your Windows audio hardware does not have a
specific ASIO driver, a DirectX driver is the next best
option.
If you attempt to hide a port that is already used by a
bus you will be asked whether this is really what you
want – note that this will disable the port!
