As you can see, there is a quite involved relation between these three parameters.
To ensure the best HD/audio performance, you would raise the Disk Block Buffer
Size, but this automatically increases the Memory per Channel which in turn limits
the possible Number of Channels. This means you will have to experiment with dif-
ferent settings to find the performance/memory/channel balance best suited for
your system.
The Apply button
Clicking the Apply button applies the settings you have made. If you get a warning
reading “Not enough memory for the Audio Engine”, you either have to decrease
the number of audio channels or decrease the Memory per Channel figure.
Try these settings first!
• Generally, start with Disk Block Buffer Size set to 64 kB and Memory per
Channel set to 256 kB.
• If you find that the audio and hard disk performance is poor (playback
stutters, system momentarily slows down), try raising the Disk Block
Buffer Size to 96 kB.
The Memory per Channel setting is automatically increased to 288 kB.
• If you need more channels, try lowering Disk Block Buffer Size to 48 kB.
● All of the above assumes your hard disk is fast enough to handle the number
of channels specified.
Audio I/O
ASIO Device
Here you select the ASIO driver you want to use. The options depend on which
drivers are available for your audio card:
• ASIO Multimedia driver.
This is the “standard” choice, for using the Windows Multimedia System to
play back and record audio.
• ASIO DirectX driver.
This option is available if your audio card has a native DirectX driver. It is also
required that you have DirectX 5 or better installed, but this is done automat-
ically when you install Cubase VST. See page 379 for details.
• Dedicated ASIO drivers.
If your audio card has a dedicated ASIO driver (that is, an ASIO driver specif-
ically written for that audio card), you should always use that driver and not
the Multimedia or DirectX drivers.
