3.Specify the sync destinations by using the checkboxes 
in the corresponding sections in the lower right part of the 
dialog.
You can output any combination of MIDI Timecode and MIDI Clock to 
any combination of outputs (however, you probably don’t want to send 
MTC and MIDI Clock to the same output).
4.Set the other device(s) to their “external synchroniza-
tion” mode (or some other mode with a similar name) and 
activate playback on them if necessary.
5.Activate playback in Cubase...

ASIO Audio Device
In this mode, Cubase LE is the slave and the synchroniza-
tion signal can be received from another device con-
nected to a digital interface of the audio hardware.
About the ASIO Positioning Protocol (APP)
The ASIO Positioning Protocol is a technology that ex-
pands on the type of sync described above and makes 
sample-accurate positioning possible.
When transferring audio digitally between devices, it is im-
portant that synchronization using word clock and timecode...

You can now set up the synchronization:
1.Open the Synchronization Setup dialog and set the 
Timecode Source to ASIO Audio Device.
2.Make the desired settings in the dialog.
For information on the different sections, click the Help button in the dia-
log.
3.Close the Synchronization Setup dialog.
4.Open the Project Setup dialog from the Project menu 
and use the Start value to set which frame on the external 
device (e.g. a video tape) should correspond to the begin-
ning of the...

cides that the tape isnt good enough to synchronize to. If 
you have a very stable timecode source, you may lower 
this number to make Cubase LE stop more swiftly after 
the tape recorder has been stopped.
Inhibit Restart
Some synchronizers will still transmit MIDI Time Code for 
a short period after an external tape machine has been 
stopped. These extra frames of timecode can sometimes 
cause Cubase LE to restart suddenly. Inhibit Restart al-
lows you to control the amount of time...

1.Connect a digital audio cable from the digital output of 
computer 1 to the digital input of computer 2.
2.Connect the other cable from the digital output of 
computer 2 into the digital input of computer 1.
If a card has more than one set of inputs and outputs, 
choose whichever one that suits you – for simplicity usu-
ally the first set is best.
Synchronization 
Before you proceed, you need to make sure that the clock 
signals on your ASIO cards are synchronized correctly.

ÖThe latency does not affect the synchronization – its 
always perfectly in time. But, it can affect the time it takes 
to send and receive MIDI and audio signals, or make the 
system seem sluggish.
To adjust the latency of a system, you adjust the size of the 
buffers in the ASIO control panel – the lower the buffer 
size, the lower the latency. Its best to keep to fairly low la-
tencies (buffer sizes) if your system can handle it – about 
12 ms or less is usually a good idea....

Activating VST System Link
Before you proceed you need to make sure that VST Sys-
tem Link is set as Timecode Source in the Synchronization 
dialog and that the desired Sync options are activated, 
see “Application options” on page 223.
After setting up the inputs and outputs, you now need to 
define which input/output should carry the actual VST 
System Link information.
The System Link networking signal is carried on only one 
bit of one channel. This means that if you have an ADAT...

For now, lets put all computers online:
1.Activate the Online checkbox in the VST System Link 
panel for all computers. 
2.Check that the system is working by pressing Play on 
one computer – all computers should start almost instantly 
and play perfectly in time, with sample-accurate precision.
The Offset setting to the right allows you to adjust 
whether one machine will play back slightly ahead or be-
hind the rest.
This is normally not needed, but occasionally with some hardware...

However, many people prefer to mix internally inside the 
computer and just use a desk for monitoring (or maybe not 
use any external mixer at all). In this case youll need to se-
lect one computer to be your “main mix computer” and 
send the audio from your other computers into this.
In the following example, we assume you are using two 
computers, with computer 1 as your main mix computer 
and computer 2 running two additional stereo audio 
tracks, an FX channel track with a reverb...

you have a Nuendo Digiset interface or 9652 card on com-
puter 1 you could use ADAT cable 1 for networking, ADAT 
cable 2 as a direct audio input from computer 2, and ADAT 
cable 3 as a direct audio input from computer 3.
You can also transmit audio via the ring system if you dont 
have enough hardware I/Os for direct audio transmission. 
For example, in a four computer scenario you could send 
audio from computer 2 into a channel in the mixer in com-
puter 3, and from there to a...
