Note

Merging Audio Device ASIO driver can connect to third party AES67 / RAVENNA devices, but a Merging device must be present on the network (PTP clock)

The Driver has been tested and qualified on Windows 10 Professional 64 bit.
Windows 8/8.1 is not supported.
Windows 32bits versions are not supported.

  1. In MAD Panel, please increase the buffer size and click on Apply.
    Usually, 384 samples for the 6/12/48(AES67) latency or 256 for the 16/32/64 latency is a good starting point.
  2. Make sure the Latency set in your RAVENNA device is set accordingly to the one in the MAD Panel (64 or 48 Samples).
  3. Performance issue : With only 1 DAW running on your computer, disconnect all your IO in ANEMAN , set the MAD Panel to use 8 in and 8 out, and set the sampling rate to 44.1.
    Connect the headphone, or another convenient low track count monitoring ; if you don't have anymore clicks,  set more I/O in ANEMAN and MAD panel to determine how many channels your system can handle.
    Usually, slow or dual core CPU are rather subject to this kind of issue
  4. Performance issue : make sure you don't use power management features in Windows.
    Go in Windows Control Panel > Power Options and select "High Performance" power plan.
  5. DPC Latency issue : some computer drivers or devices may interrupt your CPU process, which can result in distortion, glitches or drops.
    Please see our DPC Latency helper page for details.
  6. Realtek 2.5GbE Network Controllers : the default Receive Buffers value is often set to 512 by default.  Please set it to 256 (Transmit Buffers should be left to 512).
    Please go in the Windows Device Manager, and access the Network Adapters > Realtek 2.5GbE controller Properties - Advanced tab to set the Receive Buffers to 256.
  7. In MAD Panel, make sure you don't have a "Network Throttling" error message (reboot your computer in such case).
    Windows can automatically reduce the network bandwidth on some specific process.
    The MAD installer turns off this option automatically, but if for any reason this option has been turned on, you may disable Network Throttling on your system, by downloading, unzip and launch this patch : DisableNetworkThrottling.zip

MAD does not start properly at Windows startup - Restart Server required

Panel
bgColor#fff

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.

Playback in my DAW hangs / stuck.
