Using the ASIO DirectX Driver

Microsoft DirectX is a set of standards and routines for handling various kinds of

multimedia under Windows95 and Windows NT, including audio playback. Di-

rectX version 5 is automatically installed when you install Cubase VST. If you have

an audio card with a DirectX driver, you can use DirectX instead of the ASIO Mul-

timedia driver when playing back audio in Cubase VST. Using the DirectX driver

has the following beneﬁts:

•Lower latency (see page 364).

For example, this makes it easier to perform a manual mix, since the “re-

sponse time” of faders and other mixer controls will be shorter. A typical ap-

proach would be to record audio using the ASIO Multimedia driver and then

switch to the ASIO DirectX driver for mixdown (since DirectX does not sup-

port audio input, see below).

•Several applications can play back audio simultaneously.

This means that you can run Cubase VST together with a DirectX compatible

software synth, for example. Note that the application “in focus” (the one cur-

rently “at the front”) determines the audio playback format. You cannot simul-

taneously play back audio at different resolutions or sample rates.

Also, be aware that playing back audio from several applications simultane-

ously may cause clipping (digital distortion), simply because the level of the

added audio signals may exceed 0dB. If this happens, lower the outputs of the

respective applications.

•The “Sample Position” method is automatically used for synchronizing

MIDI playback to audio (see page 374).

You will not have to use the “DMA Blocks” sync method or set the size of the

audio buffers, which is an advantage.

However, there are also some restrictions:

•You can only use the DirectX driver for audio playback, not for recording!

This is because Microsoft DirectX currently doesn’t support audio input, only

output.

•The ASIO DirectX driver only works for cards with a "native" DirectX

driver.

DirectX emulation for an audio card is not supported.

●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 DirectX driver. A dedicated ASIO driver will provide low latency times

and enable audio input.
