Outputs – Stereo and Multi Output Cards
Stereo Only cards
Standard PC Audio cards, accessed via the ASIO Multimedia or DirectX driver,
normally only allow for one stereo output. With such a card you may be able to play
a large number of channels in Cubase VST, but the output is still only a mixed
stereo signal.
Multi Output Cards
There are three ways Cubase VST can access a card with more than one set of
stereo outputs:
• Via a Windows Multimedia (or DirectX) driver that caters for multi channel
operation.
Some cards come with both a stereo and a multi channel driver. You have to
select either for use in Cubase VST. We recommend that you select the multi-
channel driver.
• Via special Windows Multimedia drivers that make the card appear as several
standard PC cards, to Windows.
• Via a dedicated ASIO driver.
Some cards come with ASIO drivers specifically written for the card. This is
then the best option to choose, since it allows you to bypass the Windows
Multimedia system.
If your card fits to any of the descriptions above, you will be able to take full advan-
tage of Cubase VST’s “bus system”, see page 194.
Drivers
Cubase always uses ASIO for audio playback. With Cubase VST comes some
ASIO drivers, most notably the ASIO Multimedia driver, which serves as a “glue”
between Cubase VST and Windows Multimedia system and thus allows you to use
standard Windows compatible audio cards, see page 369. For these cards, you do
not need anything else than the latest Windows driver for the card, installed as the
manufacturer recommends. Everything else is installed with Cubase VST.
Other ASIO drivers might be added to the system, for cards that require it. Each
driver should come with its own installation program and instructions.
The technically minded might want to know that ASIO drivers come in the form of
“DLLs”. They can be located anywhere on the hard disk. The installation procedure
adds the driver to the Windows Registry. To replace or remove a driver, use the in-
stallation program that came with the driver. You should definitely avoid renaming
or moving ASIO drivers “manually”.
