- Master ASIO Host
Allows to set a Master application, that will act as a Master sampling rate device.
This list is dynamically populated, the first time you start an application set to use the Merging Audio device, it will be added to the list.
When a Master ASIO host is set, other applications cannot change the sampling rate.
Default : any application can change the sampling rate any time.
Merging Audio Device : the sampling rate is set from the panel Sample Rate setting. ASIO applications cannot change the sampling rate.
Please note that DSD Sampling rates cannot be set in that mode.
Application : Only the application set as Master ASIO Host can modify the sampling rate.
Important notes on ASIO Host and Sample rate :
Some applications may not support sampling rate change while running, refer to the manufacturer for details.
Changing the sampling while recording / playing back will obviously create drops, do not change the sampling rate during crucial real-time operations.
For further details on sample rate configurations, please see this page.
Windows WDM cannot be set as Master ASIO Host. - Sample rate
Allows to set the sampling rate, if the Master ASIO Host is set to Merging Audio Device, or if the Master ASIO Host set is not started. - Buffer size
In 48 (AES67) Framing mode, buffer sizes available are 768 - 384 - 192 (default) - 96 - 48 samples (based on 1Fs 44.1/48 kHz)
In 64 (RAVENNA) Framing mode, buffer sizes available are 1024 - 512 - 256 - 128 - 64 samples (based on 1Fs 44.1/48 kHz)
A buffer size of 192 (AES67) or 256 (RAVENNA) samples is recommended, usually stable value for all available sampling rates. Sample type
The internal Audio Engine can be set to 24bit Integer (default) or 32 bit integer (some ASIO hosts are only compatible with 32 bit integer)
Note : this setting only applies to the internal audio engine, and not to the RAVENNA/AES67 network, which currently supports 24bit Integer only. Therefore the physical inputs and outputs are not affected by this setting.
The WDM to ASIO bridge also supports 24 bit only.
DSD sampling rates do not allow 32bit sample type, MAD will automatically switch to 24 when running such sampling rate.Expand title Click here for the conversion paths graph 
- Mix safe mode
Mixes the different ASIO nodes with an extra processing buffer.
Disabling Mix safe mode will reduce the ASIO latency when one application is using the Merging Audio device.
The counterpart is that you may also get a drop / glitch, especially when you start and run several applications using MAD.
