Preferred mode to run with Horus, Hapi, Anubis, ... devices and ASIO Digital Audio Workstations
Dedicated mode to run the Merging+NADAC device, with pre-configured settings.
RAVENNA / AES67 Settings
- Primary adapter
Lists all available network ports. Select the network adapter your Merging RAVENNA/AES67 device is connected to.
- Secondary adapter
Allows ST2022-7 running mode (redundancy).
This feature requires a 2022-7 license. Without this license, the setting is unavailable.
Select the Frame mode in use ; AES67 based on 6/12/48 samples (default) or RAVENNA based on 16/32/64 samples.
Your devices all have to be on the same frame mode multiples.
See the Advanced pages user guide for further details : opens the ASIO RAVENNA/AES67 Advanced pages.
The devices discovered on your RAVENNA/AES67 network are displayed in this section.
- To access Merging devices web apps, advanced pages or firmware update, right click on the device icon.
- Inputs and Outputs
The maximum number of Inputs and Outputs available are 128 @1Fs, 64 @2Fs, 32 @4Fs and 16 @8Fs
- Bridge Channels
Dedicated Internal MAD channels, that allows routing between applications.
Details on how to configure and use the bridge channels available in the MAD Use cases.
- Note : All ASIO channels will use some bandwidth and CPU processing even if not connected to RAVENNA/AES67 devices.
Don't set it to 128 if you only need 8 !
- 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.
If an ASIO application is running, the application name and current sampling rate will be displayed (unless Merging Audio Device is set as Master)
- 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.
- 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.
- Enable WDM
Enable / disable MAD as Windows sound device.
- Inputs / Outputs
Sets the number of inputs / outputs in the MAD Windows sound device (2-4-6-8)
- Inputs / Outputs Map
Map the WDM channels into the MAD channels.
Details on how to configure and use the WDM bridge available in the MAD Use cases.
Status and additional features
Current ASIO driver sampling rate. It may differ from the sample rate set in your DAW or your device.
Should be "Running". If "no ASIO Host connected" is displayed, please refer to the Merging Audio Device Troubleshooting page.
