4 – 38 Setting up your system
Setting up clock sync
Before you proceed you need to make sure that the clock signals on
your ASIO cards are synchronized correctly. This is essential when
cabling any kind of digital audio system, not just VST System Link.
❐ All digital audio cables by definition always carry a clock signal as well as
audio signals, so you don't need to use a special Word Clock input and
output for this (although you may find that you get a slightly more stable
audio system if you do, especially when using multiple computers).
The Clock Mode or Sync Mode is set up in the audio hardware’s
ASIO Control Panel. In V-STACK, you proceed as follows:
1. Pull down the Devices menu and open the Device Setup dialog.
2. Select the VST Multitrack device and make sure the Setup tab is se-
lected to the right.
3. Click the Control Panel button.
The ASIO Control Panel appears.
4. Open the ASIO Control Panel on the other computer as well.
Please check the documentation for the other VST System Link application for details
on how to open the ASIO Control Panel (hint: in Steinberg’s Nuendo and Cubase SX,
the procedure is the same as in V-STACK).
5. Now, you need to make sure that one audio card (and only one!) is set
to be the Clock Master, and all the other cards must be set to listen
for the clock signal coming from the Clock Master i.e. they must be
Clock Slaves.
The naming and procedure for this differs depending on the audio hardware – consult
its documentation if required.
• Typically, the ASIO Control Panel for an audio card contains some in-
dication of whether the card receives a proper sync signal or not, and
the sample rate of that signal.
This is a good indication that you have connected the cards and set up clock sync
properly. Check your audio hardware’s documentation for details.
