Q-SYS Corner

QDS 10.4.1 is here and 9.13.2 LTS isn't far behind (it is mentioned in the 10.4.1 release notes. While I continue to recommend 9.13.x LTS, as time moves on and newer equipment (e.g. Cores) replace the old, moving to a 10x (or later) version will be required. 9.13.2 LTS will, once again, offer a touchscreen to the 9.13 environment (currently made TSCs have some new hardware not supported in 9.13 and below. 9.13.2 will support the TSC-70-G3, once again.

It is interesting (to me, at least) that if one wants to downgrade to 9.13.2 from 10.4.1, you have to step through 9.13.1, first. The upcoming change to the Core 24f with the updated audio board will require 10.4.1 or later.

I've updated the Eprad eCNA plugin to version 1.3.0. The key feature on this version is the addition for support of the Eprad nanoHost. The nanoHost can take in a POS schedule in BLODE format and then generate show information, including ticket sales, by show, to allow for optimizing lamp life (only turn the lamp/laser on when there are actual people in the theatre). Additionally, you can have the eCNA power up/down the individual theatres based on the actual show schedule rather than by a fixed hour. With ticket sale information, one could also shut down a theatre if no tickets were sold for the last show. Tracking when the last show's feature starts can avoid prematurely shutting the theatre down.

Combined with server plugins, particularly ones that have a "Transfer" status, one could combine plugins to ensure that when content is transferring, that a server would not be shut down until all content has finished transferring.

These sorts of plugins, for cinema, demonstrate how Q-SYS is more than just a DSP sound system. It can provide much more extensive automation control, including when augmented with conventional cinema automations like the eCNA or JNIOR.

Again, I'm putting this plugin on my github:

https://github.com/sguttag/QSYS-Plugins-UserComponents/tree/main/Eprad/eCNA

[Steve Guttag]

FYI...the eCNA plugin (as well as the DSS Server one) are also now on the Q-SYS Communities Exchange Page (you do need to be a registered user to sign in):

https://developers.qsc.com/s/exchange

The Exchange page is the "official" place for posting Q-SYS plugins and where one should go to see if there might be a script/plugin//user component that is not in Asset Manager (QDS 9.x and below) or Library Manager (QDS 10+). As of this writing, there are 23-plages on the Exchange with up to 9 components each. In general, these are supposed to be open-source and publicly hosted (Github or Bitbucket) though I've seen some that are encrypted (qplugx) too. The idea behind the page was to be a bit more open though with an exchange of ideas and samples more so than for commercial gain.

QDS 9.13.2 LTS has finally arrived. I have no doubt (unless it starts causing problems), this will be my newest preferred (presuming the Core I'm using runs on it) QDS version. Key things include putting the current-production TSC-50-G3 and TSC-70-G3 back on the usable list (there was a hardware change last fall that needed one of the QDS 10 versions to in order to work with them.

Keep QDS 9.13.1 LTS around since it is a required step if you are DOWNGRADING from a version 10 QDS before landing at 9.13.2 LTS.


Note: Before upgrading your system, review the Q-SYS Designer Software Compatibility section.
v9.13.2 (LTS)

Version 9.13.2 is a Long Term Support (LTS) release of Q-SYS Designer Software. It was released August 13, 2026 and includes these resolved issues.

There were so many fixes, I had to break this into two parts. Part 2:

• Control: Resolved performance issues with the Room Control UCI, related to sluggishness caused by pop-ups and complex layers.
• Control: Resolved an issue where button legend text set dynamically via Text Controller scripting was cut off on TSC touchscreens and Windows UCI Viewer.
• Endpoints:Resolved an issue where NM-T1 peripherals reported a grandmaster clock mismatch despite having the correct grandmaster.
• Endpoints:Resolved an issue where learned IR commands were not retained when an “IR Receiver” component was copied and pasted within a design or between designs in Q-SYS Designer, forcing users to relearn IR commands for each new instance of the device, in their design.
• Endpoints:Resolved issue where audio routed to output 2 and NV-32-H would also play through output 1 on the first playback after a design restart or core reboot.
• Endpoints:Resolved an issue where an NV-32-H configured as a Decoder in HDMI 1 + HDMI 2 output mode with MediaCast In assigned to HDMI Output 1 could experience repeated HDCP reauthentication, causing the video feed to drop to a black screen.

My Eprad Plugin has been updated to version 1.4.1.

The main new feature is Event Logging on the Core.

image.png

Note, it has to be enabled via the Properties (to reveal the Event Log tab as well as permit the logging) and then on the Event Log tab, one has to Enable the Logging. Additionally, each type of logging desired needs to be enabled individually.

I think this could be a very handy feature for tracing problems when shows don't go as planned. The Core's Event Log can set up a decent timeline as to what happened during the show.

The plugin is available on my Github repo. https://github.com/sguttag/QSYS-Plug...ain/Eprad/eCNA

I'm leaving the older versions up there too in the Archive folder.

I believe that this will be the last feature update for version 1. I do plan on a version 2 for use with the version 2 CPUs. I don't think there will be any feature updates beyond allowing for more Macros and RDIs that the version 2 CPU has brings. Plugin version 1.4.1 should work with version 2 CPUs but with version 1 limitations.

Heads up on QDS 9.13.2 LTS. If you are running redundant Core (most of my systems) and have a fair number of control systems (plugins for projectors, servers and whatnot), as that traffic increases, the status of the Core will complain about the backup Core being off line and then, quickly recover. If you are look at the status box when it happens...it will just be a flash. I've noted, at night, when all of the projectors and servers shutdown, the problem goes away.

Functionally, 9.13.2 LTS seems to be working but i cannot having the status flashing like that all day so i reverted back to 9.13.1 LTS. Where I don't have a redundant Core, there has been no issues. Thus far, it has come up on Core 110f and Core 510i. I have not tried it on Core Nano, yet. I do have a case open with Q-SYS to get it resolved.

I should also note, if you switch to the redundant Core, then the roles reverse and the momentary flash is about the Primary Core (whichever one is in standby).

QDS 10.5.0 has just dropped...and it's massive. Check out the new features in QDS. The signal highlighting is pretty cool. If you click on a wire/signal it will light up the entire end-to-end (including through router/mixers). It can convert you messy wires (I'm kinda partial to messy wires) to Signal Names (wire tags). Since it is a x.x.0 release, I'm not eager to jump into it. I'm hanging at 9.13.1 LTS for any system that can stay there. This is going to get more difficult going forward, however. The DPA line of amplifiers have gone EOS (they will no longer fix them). Most everything but the DCIO-H, that was designed/made before 2020 has now gone EOL (no longer made) and, somewhat quickly, heading towards EOS (no longer repaired). What this all means is that the new MPA-Q amplifiers will be the logical replacements for the DPA-2K4Q or CX-Q2K4 (using the MPA-Q 4x500). This will necessitate using QDS 10.4 or newer.

Heads up on updating to 10.5.0...it downloads newer .NET versions (.NET 10) and they aren't small, by comparison...so it takes some time and space.

I don't know if Q-SYS is showing their hand or not but if you check their "Compatibility by Software" page, they are removing all of the cinema speakers as well as all of the recently discontinued Cores like the 510 and 110. I believe it is a "misprint" since they are all still there in 10.5.0 but are now in the "Discontinued" section (you have to tick a box to see the discontinued stuff that is still supported). The Compatibility by Software page is perpetually incorrect (you'd never know that 9.13.2 LTS added support back for the TSC-G3 touchscreens).
