Introduction

Version 10.2.4 is a minor release version for mc² consoles based on the A__UHD Core Phase 2 technology. Version 10.2.4 adds in various new functionalities to the system.

This software release applies to the following products:

mc²96
mc²56 MKIII
mc²36 MKII
A__UHD Core
A__stage series
A__digital64
A__madi4/6 (running NodeSys 2.4.0)
A__mic8 (running NodeSys 2.4.0)
mc² Compact I/O (running NodeSys 2.4.0)
Power Core Gateway

Breaking Changes 10.2.4.0

Ember Provider Channel metering is now using the Ember streaming format instead of int64.
Compressor and Expander Hold parameter has been removed from the Ember Provider, since it actually is not available in the system.
Physical GPIOs are no longer available in Command Trigger and Ember+ Provider of MCX, but may only be used using TCL. Physical GPIOs need to be connected to vGPIOs in Home, in order to use them in MCX.
The Aux Bus pickup point has been removed, previous Aux Bus pickups are automatically converted to Aux AF (after fader).

Ensure Integrity of Device IDs

Before upgrading to the 10.2.4 release version, please review the integrity of Device IDs between the device agent and the Home Discovery service / etcd. This can be done using the NodeSysUpgrade tool. Further Information about the NodeSysUpgrade tool can be found here https://confluence.lawo.com/x/t9g4Aw.

The steps to use this tool in order to re-sync the live Device IDs with Discovery service / etcd are:

1. Run up node-sys-upgrade, passing the IP address of the NATS server to connect to, e.g. node-sys-upgrade.exe -nats 10.3.123.56
2. Type Scan to get a list of all devices in the system and their software version etc.
3. Type SyncDeviceIds -all to ensure etcd is in sync with the set of live device IDs.

New etcd version in Home 1.4

This new etcd version is not backwards compatible with the previous version of etcd which means downdating etcd is problematic. As a failsafe for any Gateserver based Home deployment, please take a backup of the database first using the command shown below and then copy it off the Gateserver as a backup.

When updating a clustered system the home update.sh script will take a backup prior to doing the update and store it in /opt/home-release/backups/

When running Home on the Gateserver, etcd backup can be invoked using the following command, the backup can be found in /root:

aker:~ # /opt/home/bin/etcdctl snapshot save backup.db

Update redundant A__UHD Cores safely

When upgrading A__UHD Cores that are part of a redundancy group, please follow the procedure below:

The primary A__UHD Core should be active.
Update the passive/backup A__UHD Core first.
After successful update - turn off the backup/passive A__UHD Core.
Update the primary A__UHD Core
When primary comes back online, power up the backup/passive A__UHD Core again.

New Features

2 Fs / 96 kHz Support

The A__UHD Core Phase 2 system does now support 2 Fs / 96 kHz. This applies for all above mentioned products, but the Power Core. The Sampling Frequency can be changed in Home per device, or for multiple devices at once. A network supports multiple different sampling rates, however devices that should work together as a system have to use the same sampling rate.

Dynamic TC Automation Support

Dynamic Automation is now officially supported in A__UHD Core Phase 2 systems. Automation passes < 10.2.4 are not compatible (no matter if created with 6.x or 10.x) and will not be loaded.
Please note, that there are several parameters, that are no longer going to be part of the Automation:

Channel format (Mono, Stereo, Surround)
Bus assignments (Aux Send Levels and Panning are still fully automatable)
VCA assignments
Channel Config incl. Direct Out pick-up point and Insert (Klötzchenreihenfolge)
Upmix (has never been part of the Automation)
Metering pick-up points
Module Link

mc²36 MKII Dynamic TC Automation Add-On

From now on, there is a purchasable software upgrade license for the mc²36 MKII in order to use it for Dynamic TC Automation, called SW AUT mc²36 MKII „Lizenz Automation mc²36 MKII“.
Article Number: UHDAUT36

mc²36 MKII 48-fader Support

The new dual-fader Panel of the 48-fader variant of mc²36 MKII is now fully supported. Make sure to adapt the system type of the console accordingly.

Pyramix OASIS Control Integration

OASIS Control Integration for the Merging Pyramix workstation has been added. The mc² console surface can now be used to remote control up to 256 channel strips of Pyramix. This includes not only Fader, Mute etc. but also all mapable items of the channel strip like EQ and Dynamics. Furthermore, machine control of Pyramix integrates seamlessly with the console.

Supported Features:

Up to 256 Strips / Channels via 256 GPCs
- Fader Level, Mute, Phase, Label (Label transfer only Pyramix to MCX)
- Panning X, Y, Z, LFE, Slope
- Strip Tools / Bus Tools for Gain, EQ, Dynamics
- Solo and Rec arm via Fader User Buttons
Machine Transport Control
- PLAY, REC, RW, FFWD, STOP
- Machine Timecode

Currently not supported:

Metering

Further information on how to configure the OASIS IO of the mc² console can be found here https://confluence.lawo.com/x/Luc4Aw.

LiveView^TMThumbnail Integration

A__UHD Core Phase 2 systems now support Video Thumbnails and Image stills in the Channelstrip again. Supported Video Thumbnail Providers are V__pro8, V__link4 and V__remote4. Image stills can be uploaded to the console manually, custom Image stills are now located in /data/config/mcx/user_thumbnails.

Further information on how to configure Thumbnail Providers can be found here https://confluence.lawo.com/x/aOc4Aw.

Breaking Changes History

PRODUCTION / SNAPSHOT INCOMPATIBLITY: Release Version 10.2.0

Release 10.2.0 introduced incompatible hash-codes, resulting in newly created external device signals in the console, being incompatible with the ones being restored from productions and snapshots. Release version 10.2.2 is required, in order to properly load and restore production files coming from 10.0.2 and 10.0.0. This only affects native Home devices like A__line devices. External Tie-lines and Third-Party proxies are not affected by this. Productions created with 10.2.0 are not compatible with versions > 10.2.0 and need manual porting! If this is required please reach out to AP PL!

BREAKING CHANGES: Version 10.2.0.x introduced breaking changes compared to previous versions

Over Snap Incompatibility:

Over Snaps that have been created with 10.0.0 or 10.0.2 release versions are not compatible with 10.2.0 and will be discarded!
Over Snaps that have been created with 6.4.0 release versions are compatible and will be loaded.

Behaviour of receivers of A__UHD Core and A__line (NodeSys):

If one routes a source stream with fewer channels (S) than the receiver (R), then only the first S audio channels of the receiver will have signal.
If one routes a source stream with more channels (S) than the receiver (R), then only the R audio channels as specified by the receiver will be present.

Ember+ Provider:

The panning granularity of all DSP channels and GPCs has been changed to +-100. Depending on the implementation of an Ember+ consumer, this may break compatibility!
Output DSP gain parameter range has been changed from -128 ... 15 to -4096 ... 480 with factor 32 in order to be consistent with other gain parameters in the Ember+ tree.

BREAKING CHANGE: Version 10.0.2.6 introduced one breaking change about NATS Relay configuration!

If the system relies on NATS Relay on the A__UHD Core (the A__UHD Core forwards NATS messages from media networks to a Gateserver in the management network, this is e.g. mandatory for mc²36 MKII) you have to adapt your system by invoking the following command on the Gateserver:

rm -r /data/config/homerm -r /data/config/nats/cluster.conftouch /data/config/nats/leafnode.conf

BREAKING CHANGE: Version 10.0.2.5 introduced one breaking change in the Ember+ provider!

Output DSP gain parameter range has been changed from -128...15 to -4096...480 with factor 32 in order to be consistent with other gain parameters in the Ember+ tree.

BREAKING CHANGES: Version 10.0.2.1 introduced breaking changes with respect to TCL configuration and Ember+ provider!

TCL Configuration File Locations:

Please be aware that from now on MCX expects its TCL configuration files in a different location. The location has been changed from /data/config to /data/config/mcx.

This change affects both physical systems, as well as mxGUIs with an externally mounted mxgui_config_share and in the case of the latter it affects the configuration for each product type individually.

For physical systems and mxGUIs the new versions include a helper script migrateEarlyPhase2Config (that can simply be invoked from CLI) to convert a set of configuration files to the new structure. In case of a physical system the script has to be executed once and then has to be followed by a reboot of the system.

For mxGUIs multiple conversions can be performed subsequently by passing an explitcit base path as the one and only argument to the conversion script.

Please note, that further custom configuration files (such as Mackie HUI or special custom configs) might need to be adapted manually!
