Pyramix 15.0 Hotfix 2 Release Notes

Network Monitoring

Network Monitoring allow for automatically monitoring Mixer Busses from an Anubis or MT48 running the Monitoring Mission.
Mixer Busses are automatically published to the Monitor Mission by Pyramix/Ovation when loading or modifying a project and made available in the Mission Sources for selection and monitoring.
Busses Names, Channel Types and Bus ordering are published and properly displayed.
Note: MERGING ANUBIS or NEUMANN MT 48 firmware 1.9.0 (or above) required, running in RAVENNA/AES67 mode (Dante not supported)
Ambisonic busses not supported (due to channel mapping)

Pyramix configuration

This feature is only available when the selected audio device in Pyramix is Merging Audio Device when running Native or MassCore.
In All Settings > Hardware > Audio Device > Network Monitoring, you can set the number of channels available for manual output connections (Channels reserved for manual I/O connections: [All, 0, 8, …]), all remaining available I/Os are allocated for Network Monitoring.
E.g. Having 24 I/Os available in MassCore or MAD, and selecting 8 Channels for manual connections will leave 16 Channels for network monitoring.

Open

Note: When changing this setting, current manual connections remain stored in the Mixer but are displayed in red if the corresponding channel is no more available but will be available and properly patched on another system or when the channel becomes available when the feature is disabled.

Note 2: Direct Out channels need to be patched to an output in order to be published to network monitoring. The patching needs to be consecutive without gaps.

Anubis configuration
This feature is only available in the Monitor Mission on both Anubis and MT48 (running firmware 1.9.0, or above) and needs to be enabled in: Settings > Sources

• Auto Discover Sources : On

  • Wildcard Filter: By default, set to DAW* which will display all Pyramix/Ovation on the network.

    • To select one single Pyramix/Ovation station, set: DAW_<Computer Name of the Pyramix Station>*

    • For advanced filtering to discover a subset of available streamer on the network, please use a wildcard format (special character) offering many filtering options:

      • c Any character representing itself apart from those mentioned below. Thus c matches the character c.

      • ? Matches any single character.

      • * Matches zero or more of any character.

New with Pyramix 15.0

New MassCore RTX Implementation

• The MassCore Network card is no longer used directly but through a RTX Virtual Adapter.  
  The card is no longer displayed in the Device Manager as a “Merging Technologies PCIe 82574L Ethernet Controller”, but is converted to "Intel 82574L Gigabit Ethernet Controller (RTX64)" and "Merging Technologies Primary Ethernet Controller".  
  When a MassCore Network card is detected, the MassCoreNIC Service will convert it automatically to the new scheme.  This operation can take a bit of time, so the 1st time the system sees a card that needs conversion, it can take 1-2 mins until it’s usable. 

• Once the MassCoreNIC card has been properly converted to the new scheme, the physical card (below in blue) will show as disabled, and is replaced by the virtual Merging Technologies Primary Ethernet Controller (below in green).
  

• The Merging Technologies Primary Ethernet Controller (and / or Secondary)  is the one used for TCP/IP communications.
  If a Static IP has to be used, it has to be set on this adapter.

• New MSC NIC Card Support (1Gb Network card, based on Intel i210 PCIe)

• ST2022-7 Mode (requires 2 MassCore NIC cards of the same model)
