2: Release 5.4.1 Changes
CueStation mixer automation changes in D-Mitri release 5.4.1 include both feature additions and bug fixes. The following two tables list
the new features and the bug fixes, in turn. Where a bug fix introduces a new feature, it is classified as a new feature.
Mixer automation feature additions in D-Mitri release 5.4.1 include:
Table 2-1 Mixer Automation Feature Additions
Mixer Automation Feature Addition Description
Set Window Peak Hold Duration subcue
There is now a "CueStation Control / Set Window Peak Hold Duration" Command that will set Peak Hold Duration on a client
computer, or all clients, from a subcue.
CueStation mixer automation bug fixes in D-Mitri release 5.4.1 include:
Table 2-2 CueStation Interface Bug Fixes
Mixer Automation Bug Fix Description
Channel Test subcue capture changes
The Channel Test subcue will now capture the settings for Loop and Offset. If the status is "Play" when the subcue is captured
(the channel test is running), the "Active Offset" will be captured as zero.
CAUTION: If the status of the Channel Test is Stop (the channel test is not running,) then the value will be captured as Play and the Channel Test will start running when the subcue is recalled.
Important: If you Update All Rows of an Output Channel Test while the Channel Test is running, the offset is captured as the
current value when the Update button is pressed
PAFL Bus Range Change
In 5.4.1 the PAFL bus now has the same dynamic range as any other bus. In previous firmware releases, there was a limit on the
dynamic range. The PAFL bus is now scaled by 4 bits (24dB) the same as regular busses and provides the same dynamic range.
CueStation User Interface
CueStation interface refinements in D-Mitri release 5.4.1 consist of bug fixes, as listed in the table below.
Table 2-3 CueStation Interface Bug Fixes
CueStation Interface Bug Fix Description
Analog Gain Control now set by text widget only.
Previous versions of CueStation had a graphic of a knob for controlling the gain setting of an analog input. The knob would
snap to the position where you clicked, making it too easy for an unintended +55dB gain change to happen if you were a few
pixels off when the knob was clicked. The knob graphic has been removed and only the text widget is in use to change the gain
of an analog input. You can type the value in to the text widget, or you can click+hold in the box and drag the mouse up and
down to increase or decrease gain.
Save Project as Default command removed
D-Mitri currently saves only one project on the server. The commands for Save Project as Default and Open Default project
were too ambiguous as the file in each case was specific to the local client computer. These commands have been removed.
VRAS ER Damping Graph corrected
The Damping graph for Early Reflections in the VRAS window did not correctly draw the filtering that was being applied. The
ER Damping graph is now drawn correctly.
D-Mitri Release Notes
Table 2-3 CueStation Interface Bug Fixes (Continued)
CueStation Interface Bug Fix Description
Channel Test changes not applied until focus lost
When using the new Channel Test function for Inputs, Buses, or Outputs, changing the selected channels for test would not be
applied until you clicked outside of the channel text widget.
Disappearing Peak Hold Bar on Meters
With a steady-sate signal (for example a constant sine wave,) the Peak Hold bar in the Meters would not be redrawn. After the
Peak Hold Duration, the bar would disappear. This has been fixed so the Peak Hold bar is always displayed when enabled in the
Display Menu.
Bus assignment is limited to available busses.
Right+Click on a Bus assignment button now shows only valid bus numbers. In previous versions it was possible to assign a bus
assignment button to a non-existent bus.
Input channel strips only show a Gain value for Analog inputs.
Previous versions the input channel strip displayed a Gain value for all inputs, even those that did not have a gain control point.
While the gain data entry box was grey, it had a value of -1 which was confusing as it implied that the gain of that channel was
-1dB. The box now displays N/A for inputs that do not have a Gain control point.
Pressing the Channel Test "Stop Output Test" button resets count to beginning of channels list.
Pressing the "Stop Output Test" button on a channel test now resets the the pointer to the beginning of the channel list. Press the
button with the pause symbol to pause the channel test without resetting the pointer.
Channel Test controls no longer include a Stop button.
The Channel Test controls no longer include a button with a Stop icon. To stop a channel test at the completion of a channel, you
toggle the same button used to Start Channel Test or you can use the button with the pause icon.
Channel Test "Skip" button fixed.
The buttons with icons for Skip+Previous and Skip+Next now work as expected. The active channel will be changed by 1 each
time one of these buttons is pressed.
Spelling error corrected in Hardware Control / Reboot IO module
The reference to the state in New England has been removed and replaced with the correct spelling, Maintenance.
VRAS Window Command+Click Control Moves now affects all Channel Selected controls
Channel Select now works correctly in the VRAS window. Previously using Command+Click* and moving a control did not
move all Channel Selected controls.
*Command+Click on Mac OS X, Control+Click on Windows
(7990) CueStation Control Commands subcues now support the use of wild-card in the Client Name field
In systems with one or more Aliases defined in the active Mixer Configuration, "*" did not work as a wild card in the Client
Name field. It is now possible to use * as a wild-card to match any character or set of characters in a Client Name.
Undo Log now shows the correct ID number for subcues modified in Preview window
When modifying subcues using the "Preview" display, the ID number of the modified subcue was displayed incorrectly in the
undo-log in the Edit menu. It was shown as SubcueID+1.
2: Release 5.4.1 Changes
Subcue Commands
CueStation interface refinements in D-Mitri release 5.4.1 consist of bug fixes, as listed in the table below.
Table 2-4 Subcue Commands Bug Fixes
CueStation Interface Bug Fix Description
DGPIO Set Ports Enabled Commands subcue now supports multiple DGPIO modules
The Commands subcue type DGPIO, command Set Ports Enabled, only worked for DGPIO unit 1. It is now possible to control
any DGPIO in systems with multiple units.
Mixer Configuration and Signal Flow
Mixer configuration and signal flow changes in D-Mitri release 5.4.1 consist of bug fixes, as listed in the following table.
Table 2-5 Mixer Configuration and Signal Flow Bug Fixes
Mixer Configuration and Signal Flow Bug Fix Description
Short Audio Dropout when setting levels to -inf in the Matrix
It was possible for a hard mute of 16 samples to happen to a random output of the matrix when an ouput was set to -inf. This was
most often observed when using SpaceMap. When this happened to a channel that was not already at -inf, there was a "glitch"
sound in that output that would depend on how loud the surrounding samples were.
Associated IO points disabled when a module is disabled in the Mixer Configuration
Disabling a module in the Mixer Configuration window now disables the IO points as well. You no longer have to manually disable the IO points to keep them from being displayed.
Bus Trajectory Stop no longer clears Matrix Rows that do not have assigned Space Maps
Previously if a matrix row did not have a Space Map assigned, recalling a "Stop Trajectory" subcue, or pressing the Stop button
on a Transporter module, would clear that matrix row. A Stop Trajectory command is now only applied to matrix rows that have
a valid Trajectory assigned and at least one SpaceMap assigned.
The Update I/O Points command in the Mixer Configuration window no longer duplicates existing outputs
The Update I/O Points to Match Hardware command in the Configuration menu in the Mixer Configuration window no longer
creates duplicate I/O points when PAFL control points were already present
Checksum Mismatch when recalling a SpaceMap subcue
Under certain conditions recalling a SpaceMap subcue could cause a Checksum mismatch to be reported in the log. This has
now been corrected.
Logging Changes
Logging changes in D-Mitri release 5.4.1 consist of bug fixes, as listed in the following table:
Table 2-6 Logging Bug Fixes
Logging Bug Fix Description
When both AVB ports are down, Cross System VLAN receiver IDs are reported incorrectly
When in a cross-system failover, the VLAN IDs are reported to the log with an offset of 256. In this situation, the VLAN ID
numbers are now reported correctly.
D-Mitri Release Notes
Table 2-6 Logging Bug Fixes (Continued)
Logging Bug Fix Description
D-Mitri processor role change messages are now more user accessible
Previously D-Mitri processors reported role changes in a numeric matrix. This has been changed to use the terms "standby" and
PROC (processor). For example: DCP-1 Role ID changed from Standby to PROC-1.
Database Update messages now use module names in place of serial numbers.
The RepDB database update messages in the log now use the module name in place of the module serial number. For example:
Sending state #44 of database to peer DCP-1.
SID Error Messages now are more user accessible
SID Error messages now are more informative by using the term "dropped packet" in place of "Packet Sequence ID gap" and
reporting the VLAN number and the Module name. For example: Receiver #0 has detected a dropped packet
(on VLAN #23 from 16In8Out-1.
Networking changes in D-Mitri release 5.4.1 include both feature additions and bug fixes. The following two tables list the new features
and the bug fixes, in turn. Where a bug fix introduces a new feature, it is classified as a new feature.
Networking feature additions in D-Mitri release 5.4.1 include:
Table 2-7 Networking Feature Additions
Networking Feature Addition Description
Cross-system IO Module Failover Support
When two D-Mitri systems are connected to pass audio between them, a failover on one system now notifies the other system to
switch to the failover VLAN settings. This allows audio to continue to pass between a systems when one system has switched to
the failover VLANs.
Networking bug fixes in D-Mitri release 5.4.1 include:
Table 2-8 Networking Bug Fixes
Networking Bug Fix Description
Disconnecting the inactive AVB cable does not disrupt audio.
In previous versions, if you disconnected the audio network cable on the AVB port that was not in use, it would cause a "snat"
on the active AVB port. In 5.4.1 the system no longer drops audio when a non-active AVB port is connected or disconnected.
CueStation connecting to previous system
Under certain conditions CueStation would connect to a previous system by mistake. As soon as the connection was made, the
error would be reported in the log and CS would disconnect. CueStation now takes care to connect to the intended system in all
Wild Tracks
Wild Tracks changes in D-Mitri release 5.4.1 include both feature additions and bug fixes. The following two tables list the new features
and the bug fixes, in turn. Where a bug fix introduces a new feature, it is classified as a new feature.
2: Release 5.4.1 Changes
Wild Tracks feature additions in D-Mitri release 5.4.1 include:
Table 2-9 Wild Tracks Feature Additions
Wild Tracks Feature Addition Description
Wild Tracks "Format Drive" now executes a secure-erase step
SolidState drives may become slower after extended use for writing. The Format Drive operation now does a low-level/secureerase of the drives blocks rather than a high-level format of the ext4 filesystem. This restores the drives original write performance.
Wild Tracks bug fixes in D-Mitri release 5.4.1 include:
Table 2-10 Wild Tracks Bug Fixes
Wild Tracks Bug Fix Description
Wild Tracks now supports 96kHz FLAC files
Wild Tracks can now record and playback 96kHz FLAC (lossless-compressed) and OGG (lossy-compressed) audio files.
DWTRX startup fault
In previous versions, the DWTRX had a memory leak of 1024 bytes every time the rt-pipe was created. This would cause a
startup problem after the mixer configuration had been sent 120 times without rebooting. This has now been fixed.
Wild Tracks recording on backup Wild Tracks module fixed
In systems with a backup Wild Tracks module, audio recording on the backup module would have 5mS to 10mS glitches once
every 10 minutes due to the backup module resync-to-primary-WildTracks function. This function has now been changed so that
there are no longer dropped samples on the backup Wild Tracks module recordings.
Wild Tracks drive label locked when reformatting
Previously the Setup Drive dialog GUI allowed the user to attempt to re-label a drive that was in the process of being reformatted. The re-label would fail without explaining why. The GUI now treats the drive label as read-only when the drive status is not
"On Line."
Wild Tracks Recording from VRAS module was offset 40mS (4096 samples)
Wild Tracks Recording had an offset of about 40mS because of a FIFO buffer. This has now been compensated for so that the
audio is placed at the start of the file and not offset by the buffer..
Wild Tracks Add Entry button was sometimes disabled by opening a file
The "Add Entry" button and others in the same row, were sometimes incorrectly disabled when a file was opened. Switching to
a different deck and back would fix it. This has now been corrected so that it no longer happens.
D-Mitri Meters round error corrected.
D-Mitri meters would truncate which could cause a difference of up to 1 dB between the displayed signal level and the actual
level. Rounding is now adjusted to the nearest dB, eg -6.01dB will appear as -6dB rather than -7dB.
Support for Cross-System Wild Tracks failover.
Wild Tracks modules now correctly increment their VLAN IDs by 256 when the local DCP module(s) respond to an external
failover and increment their VLAN IDs to the backup ID (VLAN+256.)
D-Mitri Release Notes
Miscellaneous changes in D-Mitri release 5.4.1 consist of bug fixes, as listed in the following table:
Table 2-11 Miscellaneous Bug Fixes
Miscellaneous Bug Fix Description
Intermittent Loud Noise when dcasld is restarted
When connected to a D-Mitri processor with an ssh session, restarting dcasld would sometimes cause an unexpected loud transient noise. This is something that would never happen in normal operation with a connection from CueStation. The cause has
been fixed so that maintenance operations that restart dcasld will not cause a loud transient noise on the outputs.
(see also FB case 8331, which is still open.).
Power Cycle of a DCM-2 while in DCP Failover prevented buses from being processed.
In previous versions, if a DCM-2 was power cycled while the system was using a backup DCP, the DCM-2 would not always
setup to process buses. This was only a problem with the DCM-2 and not with the DCM-4, or single DCP systems. This has
been fixed by the new DCM firmware.
I/O module control latency reduced
The serial tunnel down GNet was inefficent leading to very long latencies when all control points were sent to an I/O module
(once every 20 seconds.) This has now been reduced significantly by improving the way control messages are sent over the
audio network connection to the I/O modules.
DCIO-24 CobraNet module now supports 96k sampling rate
A previous update of D-Mitri did not support using CobraNet 96k. With 5.4.1 the DCIO-24 now fully supports running
CobraNet at the 96k sampling rate.
Note that you need to use CobraNet Discovery to set CobraNet parameters.
Duplicate Connection Manager dialog appears
On initial startup of CueStation, sometimes a duplicate Connection Manager dialog box would appear while the user was
already using the first one. This was very confusing to everyone. We have now fixed this so that it does not happen.
Channel Test Subcues now default to -30dBfs
The previous default level setting for Channel Test Subcues was 0dBfs. This was too loud when the system Grand Master was at
a normal operating setting. The new default value for the Channel Test Subcue is -30dBfs..
OSC mapping updates improved
Previously in projects with thousands of OSC mappings there was a performance problem in dmixerd that would pin the D-Mitri
module CPU for several seconds whenever any OSC mapping was changed. This has been fixed and projects with many OSC
mappings can now have them adjusted without any noticeable slowdown.
D-Mitri web server no longer limited to 128 character URLs.
The embedded web server running on D-Mitri modules previously had a 128 character limit for the URLs it received. Over 128
characters and the URL was truncated. The limit has now been expanded to 2048 characters before truncation.
2: Release 5.4.1 Changes
3: Release 5.4.1 Known Issues and Workarounds
The following table describes known problems and limitations in the CueStation and D-Mitri Updater software, and, where applicable,
provides workarounds for these problems and limitations. Each known problem or limitation is annotated by a reference number for easy
tracking through this and any subsequent D-Mitri system updates.
Table 3-1 Known Issues and Workarounds
Ref. No.
Change Description
Wild Tracks Recording of more than 16 tracks need to use a different drive than the playback drive.
Currently when doing Wild Tracks recordings of more than 16 tracks at the same time as Wild Tracks playback, you must
record on a different drive. Since the Wild Tracks module has two drives, you can use the Left Drive for Playback, and the
Right Drive for Recording. To do this edit the settings in the Wild Tracks window to the following:
Edit the File Search Path at the bottom of the Wild Tracks window to read:
Edit the Recording Path to read:
You can also use a Commands Subcue of Type Wild Tracks to set these parameters.
Rebooting an io module causes a loud pop on shutdown and noise on restart
Please disconnect or externally mute loudspeakers and power amps connected to the output of an IO module before powering off or issuing a reboot command.
The D-Mitri word clock can get out of lock range for the system when using an External Word Clock input if the external
clock signal is lost. Please make certain that when using an External Word Clock that the signal is not disconnected when in
Occasionally, CueStation will not properly display metering information.
The workaround for this problem is to disable and then re-enable UDP metering by deselecting and then re-selecting the Use
UDP Metering command in the CueStation Network menu.
This resets the metering display, which then will function properly.
DDIO-24 outputs are not sample-synchronous
Because of the use of Sample-Rate-Converters, the DDIO-24 outputs are not sample-synchronous when not locked to the
internal 96kHz master clock.
The port LED indications for D-Mitri processor modules and I/O modules do not use the same colors. A processor module
(DCP, DWTRX, DVRAS, DCM-2, etc.) will show Yellow for a working 1000BASE-T (gigabit) connection. I/O modules
show Green for working 1000Base-T connections.
When using CueConsole or Wireless network connections to D-Mitri, Multicast Listener Discovery messages can cause connectivity problems on parts of the network. A workaround for this is to filter out Multicast messages. Please contact Technical Support for details on how to setup the filtering in your control network switch.
Note that CueStation client computers with a filtered connection may not be able to look at the contents of the Wild Tracks
drives. The work-around in this case is to save a Virtual Drive file and then use it to create Wild Tracks subcues when connected over Wireless that is filtered.
When I/O modules that have not been upgraded to 5.3 or later are connected to a 5.3 or later D-Mitri system, they can receive
the wrong audio data until a valid configuration is sent to them. This could in some cases cause outputs to be routing the
wrong signals. Please update any I/O module to the current release version before using it in a system. The update will setup
output modules so that they default to being muted on power up.
3: Release 5.4.1 Known Issues and Workarounds
Table 3-1 Known Issues and Workarounds
Ref. No.
Change Description
If an audio network switch is powered cycled while in use, it is possible that gPTP (the master clock) will be lost
momentarily on the connected modules. This can cause a short burst of audio dropouts, and noises occurring at the same
level as the program audio. Once the gPTP source has been renegotiated, the audio will be clean again.
When a DCP module is physically disconnected from a D-Mitri system, failover to a backup DCP may not happen
automatically. It is possible to issue a command from the System Status window to manually switch to the backup DCP
The "Query Hardware for Configuration" command in the CueStation Mixer Configuration window does not find I/O
modules that do not have a valid configuration. You must manually enter them in to the configuration and include their
programmed tx-VLAN.
D-Mitri Updater can not find or update I/O modules unless they are in Maintenance Mode and have port AVB 2 connected to
the Control Network..
Under certain circumstances, sending a mixer configuration twice can result in I/O modules going offline.
CobraNet Discovery will crash when setting a DCIO-24 to 16 bit 96kHz
If you are using CobraNet Discovery to set the sample rate and bit depth of a DCIO-24 module. Please set the DCIO-24 to
48kHz sample rate first. Then set it to 16 bit. And then you can set it to 96kHz sample rate. This is a bug in CN Disco and not
in D-Mitri or CueStation.
