Dolby Atmos Master Import/Export

Note: Dolby Atmos Master Import/Export/Editing requires Pyramix Premium authorization.
Dolby Atmos Renderer v3.7 required

Dolby, Dolby Atmos, and the double-D symbol are registered trademarks of Dolby Laboratories Licensing Corporation.
Confidential unpublished works. Copyright 2021 Dolby Laboratories. All rights reserved.

Dolby Atmos Master Import

• Accessible under menu Project > Import Dolby Atmos ADM Master
• When a proper Dolby Atmos Master file is selected the following options are offered:
• Timeline Settings:
  • Place at Master Start Time – to import the Dolby Atmos ADM Master file in the timeline at the position specified in the master ADM file. This is important to sync the Master ADM file with video if needs be.
  • Place at Cursor – to import the Master ADM file in the timeline at the current cursor position.
    Note: in both cases Mark In and Mark Out are positioned at the beginning and end of the imported Master ADM file and a First Frame of Action (orange) Marker named FFOA is added at the proper position in the timeline, related to the position of the imported Master ADM file as chosen above.
    
    
  • New Timeline – to wipe off the current timeline and replace it by the ADM Master file.   The project takes the name of the imported ADM.
  • Paste on existing Tracks – to keep the existing timeline and insert the ADM Master file into the existing track. This is for merging multiple  ADM Master files into a single project, in this case import the first ADM Master file using New Timeline option above, then import following ADM Master files using this option. No binaural settings are imported using this option, to preserve previous or existing settings. All further ADM Master files imported with this option should preferably share the same existing Input Configuration.
    If the project already contains a CD Disc, CD Start and Stop markers are created for any imported ADM and named accordingly.
    
    
• Mixer Settings:
  • Create Strips for imported Beds and Objects – to create new Strips in the Mixer for each imported Beds and Objects. New Strips are created before any existing strips in the mixer, to match new tracks created in the timeline (see above).
    Note: It is necessary to enable this option to import Dynamic Events from the ADM Master file, so they are converted into Panning metadata for these associated new Strips.
    
    • Create Mono Strips for Beds – to create Mono Strips for all Beds channels. If not checked one single multichannel strip is created for each imported beds.
  • Create new Busses for imported Beds and Objects – to create new Busses in the Mixer and automatically patch all created strips to these busses. This option completely removes the existing mixer before creating new strips and busses.
  • Send imported Beds and Objects Strips to existing Busses – to patch/send newly created Strips to any existing Busses, Beds channels to Mix Busses and Objects channels to Object Busses. Imported Beds try to find a new Mix Bus for each to avoid mixing them together, so if using this option a set of Mix Busses should be prepared in advance to reasonably accommodate any Dolby Atmos Input Configuration.
  • Do not send imported Beds and Objects Strips – to only create new Strips and patch them to existing Busses later manually
    Note: When using the Create Busses for Beds and Objects option a completely new mixer is set to accommodate the imported ADM Master file. An Export Dolby Atmos Master done just after importing with both above options (Create Strips and Create Busses) will produce an (almost) similar ADM Master file as the original (see Export Dolby Atmos Master for details).
    Note: When using the Send imported Beds and Objects Strips to existing Busses option only the Objects Binaural Render Mode are imported to the patched Objects Busses. Existing Beds/Mix Busses keep their Binaural Render Mode settings unchanged.
    
    
  • Color Beds Strips and Busses – to color Strips and Busses relating each beds with a different color for easy identification.
    Note: Imported Master Input Configuration channels description will be used to name created Strips and Busses. Beds Busses will get the name of the imported channels, Objects Strips will get the name of their imported channels.
    Note: Binaural Render Mode of the imported channels will be transferred to the Busses channels the created Strips are patched to, so a following Dolby Atmos Master Export will inherit of the proper binaural settings. (see Edit Dolby Atmos Master Configuration section below for more details)
    

• Options:
  • Keep original Master Configuration including unallocated channels - to import unallocated channels in the current project / mixer.  This option is meant to be used when you plan to import several Dolby Atmos ADM Master files, using the same mixer / project, allowing to have different object channels for different audio (CD) tracks.  See also the Paste on existing tracks option when importing several ADM Master files.
    Limit number of unallocated Objects channels to - to create additional Strips - Objects up to the number of channels entered (max 128).
    This might be useful if you plan to import several Master files in the same project.
    Limitation : this option will not work if the last channel in the Imported ADM Master file is a Bed channel.
  • Optimize Master Configuration by removing unallocated channels - to remove the unallocated channels from the imported ADM Master file.
  • Set Frame Rate according to Master – to change the application Frame Rate according to the ADM Master File.
    
  • Create CD Markers fitting Master boundaries - (Pyramix 14 Hotfix1) to automatically add CD Start and Stop Markers when importing an ADM Master file. 
    If the project does not already contain a CD Album, a new one is created. 
    If a CD Album is already present in the project, the CD Markers are added into it. 

Dolby Atmos Master Export

• Accessible under menu Project > Export Dolby Atmos ADM Master
• This process will produce a Mixdown of the existing Timeline through the existing Mixer and wrap it as a Dolby Atmos ADM Master file.
• Channels that do not contain audio will not be exported to the final ADM Master file, however, channel numbering and source indexes will be preserved.
• The following options are offered when exporting a  Dolby Atmos ADM Master:
• Master:
  • Master Name – to give a file name to the Master, the produced file with be named <Master Name>.wav
  • Media Folder – the Media Folder the Master will be created in
    
    
• Timeline Source:
  • Whole composition – to export the whole timeline as an ADM Master file.
  • Between Marks – to export the timeline portion between Mark In and Mark Out as an ADM Master file.
  • Selection – to export the current selection as an ADM Master file.
    Note: The exported Master will have a Start Time set according to the timeline entry point of the above Source point. If a Marker in the Timeline named FFOA is found between the start and end point of the exported selection, it will be used to set the First Frame Of Action in the exported ADM Master file. 
  • CD Tracks - to export the timeline, based on the CD Album information:
    Single ADM: Single file containing all the CD Tracks (CD Album)
    One ADM per track: One ADM Master file per CD Track.
    Track Number: Track Name: One ADM Master containing the selected CD Track.
    Note: Only CD Album information are used, not SACD Album. 
    In such case, select your SACD Disk and perform a Create CD Disc from SACD Disc in the CD/SACD tab - Discs menu.
    Note on FFOA : FFOA can be inserted in a CD Track by using a CD Index marker.  Such Index marker must be named FFOA.
  • Naming : to set the naming convention for the exported CD Tracks.
    Default: Disc Performer_DiscTitle_TracKNumber_TrackTitle (Track Name in the CD/SACD Tab)
    Apple Music: Disc_UPCEAN_DiscNumber_TrackNumber
    Sony Music: TrackNumber_TrackTitle_ADMBWF (TrackTitle = Track Name in the CD/SACD Tab)
    Universal Music: DiscPerformer_TrackNumber_TrackTile_AtmosMix_Tempo_MixerInitials_StudioLocation_000bpm_BIMD.  (The tempo, studio location,...information cannot be entered by Pyramix, you will have to rename the file to enter the appropriate info.
    Warner Music: TrackNumber_Disc_UPCEAN_TrackISRC_AudioSampleRate_AudioBitDepth.
    Note: Custom naming currently not available.
  • Adjust CD Markers to Video Frames (CD Tracks mode only) - to have the CD Markers in sync with the video frames.  CD Start markers are moved to the previous video frame, CD Stop markers are moved to the next video frame.
    This setting is highly recommended to avoid Start Time/FFOA issues in the Dolby Atmos Renderer.
    
    
• Master Configuration:
  • The Master Configuration grid allows for selecting which busses are to be exported to the ADM Master file, as well as setting the Dolby Atmos Mapping mode and Binaural Render Mode. Please see details of this mapping in the section Edit Dolby Atmos Master Configuration below.
  • Edit Master Configuration: Opens the complete Master Configuration window for editing additional settings like Downmix and Trim Controls. Please see details in the section Edit Dolby Atmos Master Configuration below.
    
    
• Options:
  • Force Start Time at 01:00:00:00 - Sets the start time of the exported Dolby ADM Master file(s) to 01:00:00:00 (applies to all Source setting).
  • Real time Mix – to run the Mixdown process in real-time. This is required if the mixer has any external send/returns or any inserts running in real-time.
    
    

Dolby Atmos Master Configuration

• Accessible under menu Project > Edit Dolby Atmos Master Configuration
• Concepts & Rules:
  • The Mixer basically holds the entire Dolby Atmos configuration:
  • Beds are implemented as Mix Busses
  • Objects are implemented as Object Busses
  • Beds definition are automatically derived from Mix Busses channel definition. Bottom layer Channels can be exported as Dolby Atmos Beds or as Dolby Atmos Objects. Top layer Channels and Wide Channels of any Mix Busses are always exported as Objects
  • Dynamic Events for Objects are implemented as standard Panning Automation of any Strips patched to an Object Bus
  • The entire Dolby Atmos Configuration is derived from the above architecture by simply selecting which Bus to export, selecting which mapping mode is preferred for Beds and selecting the Binaural Render Mode for every selected Channels
  • Any Mix Busses selected in the configuration with Bed + Object Mode will create a Bed in the ADM Master file. 7.1.x busses will create a 7.1 bed plus x top objects, 5.1.x busses will create a 5.1 bed plus x top objects, stereo busses will create a 2.0 bed. 9.1.x busses will create a 7.1 bed plus two wide objects and x top objects.
  • Any Top or Wide channels of any Mix Busses will be exported as Objects
  • Any additional Mix Busses selected in the configuration with Bed + Object Mode will create an additional Bed in the Master
  • There is one exception to the above rule, 7.1.2 Mix Busses are entirely mapped to 7.1.2 Beds and no objects are created for these Busses. Any other Mix Busses containing Top channels will map them all to objects.
  • Any busses selected in the configuration as All Objects will create only objects in the ADM Master file, with one exception, if the first bus is exported as All Objects and contains a LFE then a 5.1 bed is created in the ADM Master file and that LFE sent to it.
  • Any Objects Busses selected in the configuration will be exported as Objects. The Dynamic Events for these objects will be extracted from the Strips patched to this Object Bus Channel.
  • All objects sharing the same strips have the same binaural settings over all tracks of a CD. 
    
• Dolby Atmos Master Configuration grid:
  • Bus Channels – displays all Mixer Busses and Busses Channels in the order the are created in the Mixer. This is the order they are exported to in the ADM Master file.
  • Assignment – this is the mode any Bus can be set to be mapped in the Dolby Atmos configuration:
    • None – This bus is not exported in the final Dolby Atmos Master, and its routing will be removed when pressing the Update Dolby Atmos Renderer button.
      
    • Routing Safe – This bus is not exported in the final Dolby Atmos Master, but its routing will not be modified when pressing the Update Dolby Atmos Renderer button.
    • Bed + Top/Wide Channels as Objects – this bus is exported as a Dolby Atmos Bed for all bottom layer channels and as objects for all top layer channels and wide channels
    • All Channels as Objects – all channels of this bus are exported as Objects in the final Dolby Atmos Master. LFE of the first bus in this mode is sent to main bed LFE though.
    • Only Enabled Channels as Objects - only the channels that are routed to an Object Bus will be exported as Objects.
  • Description – this is the description of all channels that will be exported in the final Dolby Atmos Master. This information is read-only and is derived from the Strips and Busses of the Mixer. The Beds are named from the Mix Busses they are mapped from and the Objects are named from the Strips patched to the Objects Busses they are mapped from.
  • Group - this is the Group field.  All channels in a Bed will be in the same group.  For Objects, each channel can be in different groups.
  • Binaural Render Mode – this is the binaural render mode exported to the final Dolby Atmos Master Input Configuration for each exported channel.
    Note for Binaural Settings in Dolby Atmos Master file containing several beds:
    The Binaural Render Mode settings must be the same for the several Beds included in the ADM Master file; e.g. if the L channel on Bed 1 has been set to Near, the L channel will also be set to Near in the following Beds.
    When a difference is detected, Pyramix will display the Binaural setting that will be exported, showing the bed description from which the setting will be applied.
    E.g. shows that the Near setting will be overridden by Mid, which is inherited from the Bed named "Bed 1-10".
    The Top Channels are not affected by this behavior, as those channels are defined as Objects in Pyramix.
    
    
• Downmix and Trim Controls:
  • Downmix Controls and Trim Controls can be set as in the Dolby Atmos Renderer configuration dialogs.
  • Set Default resets the downmix and trim controls to their default values.

• Update Dolby Atmos Renderer:
  • The current Mapping, Descriptions, Groups, Binaural Settings, Downmix and Trim Control Settings, as well as the Mixer Bus output routing, will be transmitted to the Dolby Atmos Renderer to match the Pyramix configuration. 
    The button will not be active until Pyramix is connected to the Dolby Atmos Renderer with the Dolby Atmos Connect feature (see Using Pyramix with a Dolby Atmos Renderer below). Dolby Atmos Renderer 3.7 (or above) required.
    The Pyramix Mixer Bus output routing is automatically set and transmitted to the Dolby Atmos Renderer input, based on the Dolby Atmos Mapping set.
    The unused bus channels, with Mapping set to None, will not have an output assigned and will not be routed to the Dolby Atmos Renderer. The Mixer routing of channels set to None will be removed.
    Channels with Mapping set to Routing Safe will not be transmitted to the Dolby Atmos Renderer, but the Mixer routing of such channel will not be modified. This can be useful when using additional Monitoring busses, LTC send, ...
    
    
• Export Configuration as ADM:
  • The current Mapping, Descriptions, Groups, Binaural Settings, Downmix and Trim Control Settings can be exported as an ADM "empty" file from within the Dolby Atmos Master Configuration and imported in the Dolby Atmos Renderer to match the Pyramix configuration. After import in the Dolby Atmos Renderer please selected the INPUT Source button to listen to the Pyramix output.
  • Note: A final Dolby Atmos ADM Master exported by Pyramix can also be imported in the Dolby Atmos Renderer to configure it and will produce the same results. Exporting the configuration only is of course much quicker.

Known limitations or comments

• Known limitation: Only 48kHz Dolby Atmos Masters are supported for now as export. If the source project is set at a different sampling rate then the Mixdown process will convert automatically to 48kHz using the highest quality settings of the Hepta sampling rate converter.
• Terminology mismatch: Pyramix Divergence is equivalent to Dolby Atmos Size and imported and exported as such.

Improvements

• Hotfix 2: Pyramix and Ovation Native compatible with Windows 11 .  Pyramix and Ovation Native-ASIO versions are now compatible with Windows 11, along with the Merging Audio Device driver v2.2. 
  For third party ASIO hardware compatibility with Windows 11, please consult the manufacturer documentation.
  MassCore version is currently not compatible with Windows 11.
• Hotfix 2 : Dolby Atmos Master Configuration - Assignment : Routing Safe - Prevents the Update Dolby Atmos Renderer button automatic routing mechanism to modify the output routing of the specified channels.
  This can be useful when using additional Monitoring busses, LTC send, ...
  Note : the previous  Number of bus channels connected to the Dolby Atmos Renderer Input setting has been removed.
• Hotfix 2 : Dolby Atmos Master Export - Force Start Time at 01:00:00:00 - Sets the start time of the exported Dolby ADM Master file(s) to 01:00:00:00.
• Hotfix 2 : Aux Groups routing to Object Busses - Aux Groups can now be routed to Object Busses.  
  Note: As for Multichannel strips, Aux Groups have to be connected to object busses by following the strip channel count granularity, i.e. stereo strips should be patched in the object router to 1/2, or 3/4, or 5/6, etc… 5.1 strips should be patched to 1/2/3/4/5/6 or 7/8/9/10/11/12, etc.

Additional notes

Pyramix 14 Product Changes

• Windows 7 no longer supported
• New Save format, added save special as Pyramix 25^th. 

MassCore Technical Notes

• MassCore not supported on Core2Duo. Minimum requirement is a QuadCore. Find system recommendations here: http://www.merging.com/support/pc-config
• MassCore is supported under Windows 10 (64bit).
• Pyramix 14 runs on Pyramix 25^th keys for the duration of the Pyramix 14 beta cycle
• Pyramix 14 runs on the same MassCore (RTX64 3.7.4) as of the Pyramix 25^th HotFix 3 & 4.
  MassCore is now protected by Merging key security.
• MassCore Ultra Low latency mode can generate noise if used on some configurations (Turnkey recommended).
  In such cases we recommend instead the use of the AES67 mode or Extra Low latency mode.
• Pyramix Core indicator overloading (red) issue. Recommendation:
  • Under a 64 bit OS: MassCore RTX 64bit users are allowed to run with Hyperthreading enabled. In such case users will by default have 2 Core allocated to MassCore RTX64, as we leave a pair number of Cores for Windows.
    Merging recommends to having an SMP key under such configurations.
  • If, under the Bios power options, you have entries such as the Intel SpeedStep and CPU C State make sure that these options are disabled, as they are potential problems for MassCore. Refer to installation guide or the Windows Configuration guide for all details.
• MassCore & CPU load indicator range (as of Pyramix v10.2 and above)
  • Green from 0% to 74% = Safe mode*
  • Orange from 75% to 84% = Moderate Risk*
  • Red from 85%->100% = High Risk
    *MassCore users will have enhanced Core stability when using recommended dedicated Graphic Cards.
    *Native users: Recent laptop owners are often confronted with performance problems when the CPU load is near the mid-point of load, where random CPU jumps can cause sudden glitches. This has also been seen when benchmarking with Non-Merging Applications on recent laptops.
• When the Core indicator blinks (red), it indicates a drop. Only be concerned if it occurred during Playback/Mix down or Record. To reset the Core drop simply click on the Core indicator. For more information please refer to the appropriate section in the User Manual.
• If you have VST Core peaks under MassCore, users should increase their VST Engine Buffer size value, located under the Pyramix Settings. More information is available in the User Manual.
• External Insert plug-ins: The same input and output cannot be used in the External Insert plug-in and the Mixer at the same time, as they are exclusive to either one.

Plugin Engine Notice

The plugins engine Core distribution is done automatically for optimal performance. The total Core load of the Strips plugins will be processed first, followed by the total Core load of the Bus plugins. The engine is sequentially performing those two processing tasks. Meaning that a high Core load on the Strips plugins side is not summed with a high Core load on the Bus plugins side.
Changing a designated Core load to another one is not possible (unless modifying the Mixer configuration) and in no way would it change the total sum of processing passed to the engine for the chosen plugins.

About the Plugins Distribution Core Reading
We measure the time duration of the plugin itself. Time to process Audio Frame / Duration of the plugin itself * 100 = Load for a single plugin. We then compute the multiple plugins (on a chosen Strip or Bus by example) and we calculate the summation of those.

Do not to confuse with the readings below :
Pyramix CPU reading:
The CPU load displayed in the Pyramix bottom bar is not the CPU usage as computed in Windows task manager. CPU load in Native is computed in this way: (time to process audio frame) / (duration of one frame) * 100. Thus, it is the percentage of time used to process in one audio frame duration; this indicator is more useful than CPU Usage because it takes in account CPU stall during processing time.
In MassCore based systems the CPU: load indicator is supplemented by a VST: Core load indicator in the Title Bar. Refer to the Pyramix User Manual for more details.
Windows Task Manager:
Then windows will on its Task Manager CPU measures the CPU time as a percentage of the CPU's capacity.
So, in the end you just cannot open those 3 Windows and expect to have the same readings.

Merging Audio Device (MAD) 2.0

This ASIO RAVENNA/AES67 device supports Multi ASIO Clients and integrates WDM Support.  With this new Device Driver multiple applications running ASIO can be launched in parallel on a same system, sharing the same sampling rate and at the same time multiple applications running WDM can be launched in parallel and have their own sampling rate automatically converted to the ASIO sampling rate. This allows monitoring the Windows system sound and any application (such as Spotify, YouTube, PC Sounds files,…) along with any ASIO applications.
Refer to the online MAD documentation for all details https://confluence.merging.com/display/DSI/MAD+Docs

• • Two different modes supported
    • Unite Mode (Automatic Simplified connectivity for Anubis Music Mission, Horus and Hapi). Unite does not support the Anubis running the Monitor Mission.
    • RAV/AES67 mode (Pro usage for Anubis, Hapi and Horus)
    • NADAC mode (HiFi usage for NADAC users)
    • MassCore mode
  • Multi-Client ASIO and thus hosts supported  
  • Bridge channels support between ASIO clients
  • WDM Support and second AUX WDM (as of MAD 2.0)
  • Bridge channels support for WDM and Host.
    Note: One sampling rate at a time supported for ASIO (The default host one). WDM supports SRC.

MAD Infrastructure Pack (PSO-MAD-INF) required for:

• • Virtual Machine Support
  • ST2022-7 Support
  • NMOS Support

ANEMAN

Important: The ANEMAN comes as a separate installer.
Please download and install the latest ANEMAN in order to manage and monitor your AoIP devices from https://www.merging.com/products/aneman

Ambisonic

Since Pyramix 12 we include a complete hybrid Channel Based/Ambisonic workflow, allowing for encoding, mixing, rotating and decoding Ambisonic signal directly in the mixing console.

Ambisonic Decoders:

• • Ambisonic Decoders supported up to 7th in v12, and the b<>com Decoders are now integrated within the Pyramix mixer as of Pyramix 12.0 and upwards.

 VR Pack Key option:

• • Ambisonic Strips and Ambisonic Groups of 1st and 2nd order are always decoded even if the VR Pack key is not present
  • Ambisonic Strips and Ambisonic Groups of 3rd to 7th order are properly decoded if the VR Pack key is present
  • Ambisonic Strips and Ambisonic Groups of 3rd to 7th order are decoded using a 2nd order decoder if the VR Pack key is NOT present

To summarize, a user will need the VR Pack key to encode and/or decode HOA, meaning 3rd to 7th order. 1st and 2nd orders are free of charge for both encoding and decoding.
Note: HOA to Binaural is not available into Pyramix but users can run the B<>COM Binaural encoder licence, available in trial. Follow the instruction here for more information https://confluence.merging.com/display/PUBLICDOC/Bcom+plugins

RAVENNA Technical Notes

• Windows 10 (64bit) is supported by Pyramix 14 MassCore RAVENNA and Native
• Windows 11 (64bit) is supported by Pyramix 14 Native
• Pyramix 14 system recommendations. Details here: http://www.merging.com/pages/pcconfig
• For ultimate performance we recommend that under ANEMAN you only connect the necessary I/O connections, as every extra RAVENNA connection will use some bandwidth (Core or Network)
• The Network must be Layer 3 compliant and must be a Gigabit network
• Merging has certified new Network Switches for use with Horus/Hapi – Ravenna users will find all details along with the configuration guide here:
  https://confluence.merging.com/display/PUBLICDOC/Network+Switches+for+RAVENNA+-+AES67
  http://www.merging.com/products/horus/downloads
• RAVENNA users should avoid connecting multiple Horus or Hapi units to any a router/Network not certified by Merging. Refer to the Merging RAVENNA Network Guide for details on the certified RAVENNA switches and their configuration. http://www.merging.com/products/horus/downloads
• Only RAVENNA devices can be connected to the Merging PCIe Ethernet Controller Card NET-MSC-GBEX1. Avoid connecting non-RAVENNA devices to this network, such as Tango/Isis/Euphonix controllers or other network devices.
• Don’t connect a 100MB Ethernet device if the switch is not multicast; otherwise, the flow control will reduce the bandwidth drastically.
• RAVENNA I/O Connections:
  In order to create RAVENNA I/O connections please refer to the ANEMAN User Manual (installed along with Pyramix). ANEMAN Quick Connection Guide here below.
  https://confluence.merging.com/display/PUBLICDOC/ANEMAN+-+Quick+Connection+Guide
  Refer to the ANEMAN User Manual for more details.
  Recalling RAVENNA connections for a complete setup.
  Despite not yet having a complete recall of IO Connections it is possible on certain setups to recall the Presets store in the device (Horus, Hapi, Anubis) that holds one end of the RAVENNA connections and at the same time recall the ANEMAN save connections that holds the other connections end.
  Warning: It is strongly advised that before recalling connection that users clear the existing connections.
• Firewall:
  Firewalls can block communication between the computer and the Ravenna devices.
  The Merging installers automatically opens the required communication ports in the Windows Firewall.
  If you don’t use the Windows firewall or if you encounter connection issues, we recommend to disable the Network Firewall.
  Windows Firewall Procedure:
  Go in Windows Control Panel > Windows Firewall.
  Click on “Turn Windows Firewall on or off”
  Go to the Public Network section and select “Turn Off Windows Firewall”
  For other firewalls, please consult the manufacturer documentation.
• Windows UAC:
  User should disabled the Windows User Account Control
  Procedure:
  Go to the Windows Control Panel\All Control Panel Items\User Accounts
  Open the Change User Account Setting
  And set it to “Never Notify”
• Antivirus:
  Some Antivirus such as Avast or Sophos have been known to block the Horus discovery and RAVENNA I/O Connection. Merging also recommends that any Antivirus software is properly configured to not interfere with the DAW. See this page for further details:
  https://confluence.merging.com/display/PUBLICDOC/Antivirus+and+Merging+Technologies+Softwares

  Recommended specification: 
  https://confluence.merging.com/pages/viewpage.action?pageId=24608853
• Custom installation is known to potentially have issues at installation. We recommend that you install the recommended full Pyramix.
• Pyramix 14 Projects are not backward compatible with Pyramix 25^th Anniversary, users must perform a “Save Special as v13.0 / 25^th Anniversary” in order to open such project in 25^th Anniversary.
• Pyramix projects with v10/v11/v12/25^th/14 Bus layout/Structure cannot be saved within a Save Special v9.0 project. A warning message will prevent you from doing so.
• All of the Mixer Amibsonic components cannot be saved within a Save Special v11.1 project and prior, as Ambisonic was not supported at that time.
• Ambisonic decoders only decode to Virtual Rooms with standard channel types and positions. If a custom room is needed, then they need to first decode to a standard bus, having speakers as close as possible to the custom room, then send that bus into the custom bus through a GPS strip
• Saved projects with some tracks unmuted (so that audio plays) will open with all tracks Muted.
  You are most probably using a Source/Destination project or Template Pyramix where all Track Groups are set to Auto-Solo, Auto-Mute or both by default.
  With both settings enabled at project loading time no track is selected by default and all track groups are then muted.
• Legacy Bus conversions to New General Bus. Due to the architecture of the new busses, mono mix busses are now converted to Mono Aux busses and not anymore to Mono Mix busses. Refer to the Pyramix User manual for more details.
• The listing of the Pyramix supported remote controllers is available here
• Mixdown SRC: The SRC option in the Mixdown is shared with the Media Manager Sampling Rate Conversion tool. Be warned that following a Mixdown that is applying a SRC if you then use the Media Manager Sampling Rate Conversion tool and change the SRC parameters, then those values will also be changed in the Mixdown Dialog Box SRC section.
• Pyramix Video in timeline: if the Video file is shown as offline at project opening, please refresh your media manager to regenerate the Quickmount
• Pyramix Video in timeline: Opening a project referring to multiple video files or edits can take some time (will indicate finishing for a minute or so), be patient.
• Merging does not recommend users that edit while recording do so with timeline media clips that are not at the same sampling rate as the project. This is because a realtime SRC will have be processed could cause potential performance problems.
• Waves plugins users running with a NVidia graphic card should make sure that they have the Threaded Optimization OFF, if set to ON it may cause issue with Waves VST plugins.
  Refer to link here: https://confluence.merging.com/display/PUBLICDOC/Graphic+cards+recommended+settings

• DiscWrite known issues”: https://confluence.merging.com/display/PUBLICDOC/Disc+Write
• The ADR Keyboard users: Windows 10 October 2018 Update (1809) and higher requires ChangeMe version 5.25.8.  Previous versions will not work along those Win10 updates. Follow the installation instruction on our knowledge base to update :
  https://confluence.merging.com/display/PUBLICDOC/Pyramix+ADR+and+Ovation+keyboard+install+guide
• Safety Record issue with the take logger: Pressed commands will be applied incorrectly when the transport is stopped. This means that if you press Abort & Delete while in Safety Record, nothing will happen. However, when you come out of Safety Record and Stop, it will apply the command, and delete the take. Handle with care.
• Multiple projects opened simultaneously: We do not recommend users to having more than 8 Projects open at the same time (due to GDI object limitation).
• Cedar users should install the latest certified version for Pyramix 64bit
  https://confluence.merging.com/display/PUBLICDOC/Cedar+Renderer

• Interchange: A non-embedded AAF export to Pro Tools 7x could generate “Could not complete your request because an unexpected error happened while trying to find an audio media file’s format” error message. We recommend the use of AAF Embedded when exporting to ProTools 7. ProTools 8 known to be working properly in this case.
• Media Recoverer and DSDIFF Recoverer, those utilities should allow you to repair a corrupted file
  https://confluence.merging.com/display/PUBLICDOC/Media+Recoverer

RAVENNA Known issues

• RAVENNA: Switching from MADI Standard (56) to MADI Extended (64) can generate a small glitch, so please avoid doing so during realtime operations
• Merging recommends the use of ANEMAN in order to manage all RAVENNA I/O connections, please refer to the ANEMAN User Manual installed with Pyramix for more details.
• Non-certified RAVENNA configurations might not be capable of sustaining 384 I/O channels @ 1FS (44.1/48 kHz). If you experience noise similar to static, reduce the RAVENNA I/O channel count enabled in ANEMAN. We also recommend that if you have experience such static noise, do not run MassCore in Ultra Low or Extra Latency mode but rather Low latency mode.
• Peaks might show up under the Pyramix Core section if you power OFF or disconnect the Horus/Hapi. Recommendation: A valid connection to an online Horus is always required if the Horus is PTP Master. Reset peaks by Mouse Clicking on the Core indicator section.
• Avoid changing a network address, or disconnecting Ethernet ports on your system when MassCore RAVENNA is running
• ANEMAN quick connection guide available here
• DSD issues
  • Background Recorders: If the Mixer is not a DSD compatible Mixer (square mixer), the record fails, but no message will be displayed. We recommend that users create a DSD project prior to enabling and starting to work with Background Recorders in DSD.
  • When creating/opening a DSD project the Horus might not switch accordingly between 64/128/256. This has to be done manually.
