Steinberg VSL2020 Audio Card User Manual

							VSL 2020 — 11
9.2 Confi guring the VSL 2020
The control panel provides two menus called File and Confi g. The File menu is used to exit the 
control panel. The Confi g menu provides a number of options for the confi guration of your card. 
The following sections describe the confi guration options.
9.2.1 Mouse Wheel
The fi rst submenu is called Mouse Wheel. If you are using a wheel mouse, you can use the 
options in this submenu to set the “resolution” of the wheel action, i.e. how far the sliders move 
when moving the wheel. Step 1 is the “fi nest” and Step 8 the “coarsest” resolution.
9.2.2 Latency
The second submenu is called Latency. Here you can set different buffer sizes for the ASIO 2.0 
driver.
There are 2 different sections:
A list of buffer sizes from 128 samples (3 milliseconds at 44.1 kHz) to 2048 samples (48 
milliseconds at 44.1 kHz) and Ultra Latency, with buffer sizes from 96 samples (2,5 miliseconds) 
to 32 Samples (0.75 miliseconds). When you are using a VST host program that supports ASIO 
2.0 you should start with a latency of 256 samples or 512 samples to see if card operation is 
stable with your confi guration. If you are only using VST instruments you can lower the buffer size 
to achieve better playing performance. Everything under a buffer size of 512 samples will not be 
heard as latency. An advanced piano player should use a buffer size below 256 samples.
9.2.3 Factory Default
The third submenu is called Factory Default, which simply resets all settings to the factory defaults 
of the VSL 2020.
9.2.4 Always on Top
When you activate the Always on Top option, the control panel will always be the top window, 
regardless of what other application windows are open.

9.2.5 Hardware Confi guration
This option opens the dialog for hardware confi guration.
Internal Clock can be set to 32, 44.1, 48, 64, 88.2 or 96 kHz. External Clock determines from 
which source you receive a clock signal. The card then functions as a clock slave to an external 
clock device. Sources could be ADAT 1 or ADAT 2 or S/PDIF and Extra (word clock).
When you activate the S/MUX option, the sample rate on the ADAT ports is increased to 96 kHz. 
Since ADAT streams are normally limited to a maximum 48 kHz, you have to split the audio stream 
to create two 4-channel audio streams. You can then transfer a signal of 8 channels with 24 bits/96 
kHz. Your ADAT digital mixer or AD-DA converter must also support this feature, otherwise you 
cannot hear the signal.
 
The Extra In Clock setting can be either Card Sync, Word, FS or FS 256.
Card Sync refers to the 2 pin connector on the card. Word is taking an incoming word clock signal 
as the sync source. FS 256 will sync your system to a super clock.
The Extra Out Clock option will slave external devices to your internal clock settings.
You can choose between two settings: FS, which is normal word clock, or FS 256, which is super 
clock, transferred through the word clock output connector.
The S/PDIF type is either Pro, i.e. AES/EBU, or Consumer, which is the normal coaxial S/PDIF 
used to connect to your home hifi  system.
You can set the internal clock to either Auto or Lock. If you choose the Auto option, the card will 
sync to an incoming audio clock signal received from a host application like Cubase or Nuendo. 
If you choose the Lock option, you lock the settings for the internal clock, i.e. even if applications 
try to access the card with a different sample rate it will not follow. Note that this can sometimes 
cause errors with programs that do not support your selected sample rate!

9.2.6 Analog Mixer 
The Analog Mixer option opens a dialog where you can set the output level and the input level of 
the analog connectors.

10. Working with ASIO 2.0
Once you have successfully installed the VSL 2020 card, open your host application (e.g. Cubase 
or Nuendo), open the Devices menu and choose the Device Setup option. In the Devices list, 
select VST Multitrack. On the Setup tab, select the ASIO 2.0-VSL 2020 driver from the ASIO Driver 
pop-up. Click the Control Panel button to open the card control panel if you want to make your 
settings from within your host application.

11. Working with V-STACK
You can use the VSL 2020 card with any VST host application that supports ASIO 2.0, e.g. Cubase 
or Nuendo. The V-ST
ACK software supplied with your card is also a ASIO 2.0 compatible VST 
host application, and can be used in combination with another computer running Cubase or 
Nuendo.
With V-ST
ACK you can set up a VST System Link network synchronized via the ASIO 2.0 
protocol. Just like Cubase or Nuendo, V-ST
ACK provides the Device Setup dialog where you can 
select the VST Multitrack device and choose the ASIO 2.0-VSL 2020 driver option from the ASIO 
Driver pop-up menu. In the Devices list, select Default MIDI Ports and set the VSL 2020 MIDI input 
and MIDI output as your desired MIDI ports.
Once these settings are made, select VST System Link from the Devices list, select Active and set 
up the connection to the “master PC“ in your network. You can then communicate with the “master 
computer“, provided that VST System Link is activated and running.

Some things to check and observe when using V-STACK
- The fi rst and most important step is to link each computer so that each shows in the list of 
connected computers without errors. Please make sure that everything is properly locked and 
clock synced.
- You need to get the audio clock straight, one (!) machine must be clock master, all others must 
be properly confi gured for clock slave operation! This is essential for smooth operation of the 
network!
- All machines with loaded projects have to use the same sample rate!
- Make sure to use digital cables when connecting via S/PDIF, normal analog RCA (audio) cables 
will not work!
- Always use 32 bit ASIO drivers! 16 bit drivers will most likely not work. Some ASIO drivers have 
different bitwidth when using certain buffer sizes.
