11. Configuring the HDSPe AES 
11.1 Settings Dialog 
Configuration of the HDSPe AES is done via its own settings dialog. The panel 'Settings' can be 
opened: 
•  by clicking on the hammer symbol in the Task Bar's notification area 
The mixer of the HDSPe AES (TotalMix) can be opened: 
•  by clicking on the mixer icon in the Task Bar's notification area 
The hardware of the HDSP system offers a number of helpful, well thought-of practical functions 
and options which affect how the card operates - it can be configured to suit many different 
requirements. The following is available in the 'Settings' dialog: 
•  Configuration of digital I/Os 
• Synchronization behaviour 
•  State of input and output 
•  Current sample rate 
• Latency 
Any changes made in the Settings 
dialog are applied immediately - 
confirmation (e.g. by clicking on OK 
or exiting the dialog) is not required. 
However, settings should not be 
changed during playback or record if 
it can be avoided, as this can cause 
unwanted noises. 
Also, please note that even in 'Stop' 
mode, several programs keep the 
recording and playback devices 
open, which means that any new 
settings might not be applied 
immediately. 
The tab About includes information 
about the current driver and 
firmware version of the HDSPe AES. 
The status displays at the bottom of 
the dialog box give the user precise 
information about the current status 
of the system, and the status of all 
digital signals. 
Buffer Size 
The setting Buffer Size determines the latency between incoming and outgoing ASIO and WDM 
data, as well as affecting system stability (see chapter 11.1). 
WDM Devices 
Not before Vista the OS had been capable to handle more than 32 WDM stereo devices. There-
fore under W2k/XP it often makes sense to intentionally limit their number.
