ASIO-Multiclient
RME audio interfaces support ASIO multi-client operation. It is possible to use more than one
ASIO software at the same time. Again the sample rate has to be identical, and each software
has to use its own playback channels. Once again the same inputs can be used simultaneously.
RME's sophisticated tool
DIGICheck
is an exception to this rule. It operates like an ASIO host,
using a special technique to access playback channels already occupied. Therefore DIGICheck
is able to analyse and display playback data from any software, no matter which format the
software uses.
Multi-Client and Multi-Channel using WDM
The WDM streaming devices of our driver can operate as usual stereo devices, or as 8-channel
devices. The option
Interleaved
in the Settings dialog determines the current mode.
Interleaved not active:
The WDM devices operate as usual stereo devices. The multi-client op-
eration works as described above with WDM, ASIO and GSIF.
Interleaved active:
The WDM devices can also be used as 8-channel devices. Unfortunately the
Kernel Mixer, active with any WDM playback, then always occupies and blocks 8 channels at
once, even when WaveLab or the Media Player perform just a stereo playback (2 channels).
So:
If the Loudspeaker device is used, the whole 8-channel group is blocked. As a result, no
second stereo pair of this group can be used, neither with ASIO nor GSIF.
The two 8-channel groups are: channels 1 to 8 and 9 to 16.
Starting ASIO or GSIF playback on any of the stereo pairs of an 8-channel group prior to start-
ing a WDM playback will prevent the Kernel Mixer from opening the 8-channel device, as two of
its channels are already in use. The Kernel Mixer then automatically reverts to open a stereo
device for a stereo playback.
An 8-channel playback using the Windows Media Player requires the speaker setup 7
.1 Sur-
round.
