Setting up your system
Optimizing audio performance
This section gives you some hints and tips on how to get
the most out of your Cubase system, performance-wise.
Some of this text refers to hardware properties and can be
used as a guide when upgrading your system. This text is
very brief. Look for details and current information on the
Cubase web site (see “How you can reach us” on page 7)!
Two aspects of performance
There are two distinct aspects of performance in respect
to Cubase:
Tracks and effects
Simply put: the faster your computer, the more tracks, ef-
fects and EQ you will be able to play. Exactly what consti-
tutes a “fast computer” is almost a science in itself, but
some hints are given below.
Short response times (latency)
Another aspect of performance is response time. The term
“latency” refers to the “buffering”, i.e. the temporary stor-
ing, of small chunks of audio data during various steps of
the recording and playback process on a computer. The
more and larger those chunks, the higher the latency.
High latency is most irritating when playing VST Instru-
ments and when monitoring through the computer, i.e.
when listening to a live audio source via the Cubase mixer
and effects. However, very long latency times (several
hundred milliseconds) can also affect other processes like
mixing, e.g. when the effect of a fader movement is heard
only after a noticeable delay.
While Direct Monitoring and other techniques reduce the
problems associated with very long latency times, a sys-
tem that responds fast will always be more convenient to
work with.
• Depending on your audio hardware, it may be possible
to “trim” your latency times, usually by lowering the size
and the number of buffers.
For details, refer to the audio hardware documentation, or, if you are us-
ing a DirectX driver under Windows, the dialog help.
System factors that affect performance
CPU and processor cache
It goes without saying that the faster the computer pro-
cessor, the better. But there are a number of factors that
affect the apparent speed of a computer: the bus speed
and type (PCI is strongly recommended), the processor
cache size and of course, the processor type and brand.
Cubase relies heavily on floating point calculations. When
shopping for a processor, please make sure you get one
that is powerful in calculating floating point arithmetics.
Note also that Cubase features full support for multi-pro-
cessor systems. So, if you own a computer system with
more than one processor, Cubase can take advantage of
the total capacity and evenly distribute the processing load
to all available processors. See “The advanced options” on
page 22.
Hard disk and controller
The number of hard disk tracks you can record and play
back at the same time also depends on the speed of your
hard disk and hard disk controller. If you use E-IDE disks
and controllers, make sure that the transfer mode is DMA
Busmaster. Under Windows, you can check the current
mode by launching the Windows Device Manager and
looking for properties of the IDE ATA/ATAPI Controller’s
primary and secondary channel. DMA transfer mode is en-
abled by default, but may be turned off by the system
should hardware problems occur.
Audio hardware and driver
The hardware and its driver can have some effect on re-
gular performance. A badly written driver can reduce the
performance of your computer. But where the hardware
driver design makes the most difference is with latency.
This is especially true when using Cubase for Windows:
• Under Windows, ASIO drivers written specifically for
the hardware are more efficient than a DirectX driver and
produce shorter latency times.
!
Again, we strongly recommend that you use audio
hardware for which there is a specific ASIO driver!
