Please check the IP adresses, your ASIO network card and the RAVENNA device(s) must be in the same range.
If your Merging RAVENNA/AES67 device is configured to use its default IP addresses, it will be 169.254.xxx.xxx, then your Native network adapter have to be in the same range 169.254.xxx.xxx
If the default IP address (Auto) is used in the your Merging RAVENNA/AES67 device, your network card have to be set to use an automatic IP address.If you have several network adapters, make sure that the other networks are NOT in the same IP range, Windows is not able to handle 2 networks with the same range.
If the RAVENNA network is using the 169.254.xxx.xxx range, your other network(s) should for example be set to 192.168.xxx.xxx.
For further help on IP addresses, please see this page.MAD requires to have a Merging RAVENNA/AES67 device on the network, for clocking. This Merging RAVENNA/AES67 device must be the PTP Master (clock icon in ANEMAN), but no additional audio connections are required (unless you are running in NADAC mode).On some specific systems (usually on Windows Server or Virtual Machines), right after Windows startup, MAD is not running properly (e.g No ASIO Host, ASIO Clock Missing,...). A manual "Restart Server" is required. This happens if the system and the selected network adapter are not fully initialized when MAD starts.
To avoid this issue, it is possible to delay MAD startup, with a registry key.
Please download MADStartupDelay.zip, unzip and follow the instructions in the README file. |

When you start a second application, the Mixing Mode may need to be adjusted, see the Mix Safe Mode option: - If the Mix Safe Mode is checked, then the MAD will always introduce one latency to perform the multiple applications mixing safely.
- If the Mix Safe Mode is unchecked then the MAD will have no latency when only one application is connected.
It will have one latency when a second applications is connected to perform the multiple applications mixing.
In such case, a transition is required to perform the latency change, which can cause a glitch when you start a second application.
