NOTE
We recommend that you use audio hardware for which there is a specific ASIO driver.
This is especially true when using Cubase for Windows:
Under Windows, ASIO drivers written specifically for the hardware are more efficient
than the Generic Low Latency ASIO Driver and produce shorter latency times.
Under Mac OS, audio hardware with properly written Mac OS (Core Audio) drivers can
be very efficient and produce very low latency times.
However, there are additional features only available with ASIO drivers, such as the ASIO
Positioning Protocol.
Settings That Affect Performance
Audio Buffer Settings
Audio buffers affect how audio is sent to and from the audio hardware. The size of the audio
buffers affects both the latency and the audio performance.
Generally, the smaller the buffer size, the lower the latency. On the other hand, working with
small buffers can be demanding for the computer. If the audio buffers are too small, you may
get clicks, pops or other audio playback problems.
Adjusting the Buffer Size
To lower the latency, you can reduce the buffer size.
PROCEDURE
1. Select Devices> Device Setup.
2. In the Device Setup dialog, select the driver from the devices list.
3. Click Control Panel.
4. Windows: Adjust the buffer size in the driver dialog that opens.
5. Mac OS: Adjust the buffer size in the CoreAudio Device Settings dialog.
Multi Processing
Multi processing distributes the processing load evenly to all available CPUs, allowing
Cubase to make full use of the combined power of the multiple processors.
Multi processing is activated by default. You can find the setting in the Advanced Options of
the Device Setup dialog.
VST Performance Window
This window shows the audio processing load and the hard disk transfer rate. This allows you
to verify that you do not run into performance problems when adding effects or plug-ins, for
example.
To open the VST Performance window, select Devices> VST Performance.
