12.5 Multi-client Operation

RME audio interfaces support multi-client operation. This means several programs can be used

at the same time. Also all formats (ASIO, WDM, GSIF) can be used simultaneously. The use of

multi-client operation requires to follow two simple rules:

• Multi-client operation requires identical sample rates!

I.e. it is not possible to use one software with 44.1 kHz and the other with 48 kHz.

• Different software can not use the same channels at the same time.

If for example Cubase uses channels 1/2, this playback pair can't be used in WaveLab, no mat-

ter if ASIO or WDM. However, this is no limitation at all, because TotalMix allows for any output

routing, and therefore a playback of multiple software on the same hardware outputs. Note that

identical inputs can be used at the same time, as the driver simply sends the data to all applica-

tions simultaneously.

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.
