Linux public beta (4408)

[x42]

We used to always duplicate everything in a way that you could switch over to the alternate setup when something failed.
We would only get a momentary glitch that way and not have to stop to fix anything.

Smart!
If someone knows a clever way of doing this with Jack and a Linux setup, please let me know.

I've seen big broadcast systems that have 3 PC with 3 different OSes and 3 different DAWs (all set up in the same way). If you just duplicate the system you also duplicate the single-point-of failure. Feeding the same system with the same input will trigger the same bug (if any) and would only account for hardware failure.

Dedicated hardware solutions have similar internal failover systems.

..end off-topic.

Part the initial OS setup on Mint I check the IRQ service for the 1010LT card with rtirq-init and add:

RTIRQ_NAME_LIST="snd_ice1712"

In /etc/default/rtirq. Then check it out:

% /etc/init.d/rtirq start
Setting IRQ priorities: start [snd_ice1712] irq=18 pid=547 prio=90: OK.

rtprio in audio.conf, the scaling governors are also adjusted. I check latency with jdelay and an audio cable from/to the 1010LT. Current jackd buffers are:

% cat .jackdrc
/usr/bin/jackd --sync -T -P80 -ndefault -dalsa -dhw:M1010LT -r44100 -p256 -n4

And of course, the low-latency Mint kernel.

[Jack Winter]

A realtime-kernel is all about reliability and can provide you with guarantees.

It's so called "soft realtime", it doesn't provide any guarantees at all like a turnkey system does. You'd have to validate that the system can satisfy your mission parameters, and even then. And if you add or change some component, then you'd have to validate it's suitability yet again.

But I agree, a so called low latency kernel is far from suitable for such use..

Edit: And revalidating the system goes for both hardware and software changes!

...sigh...but cheer up, glokraw, picking nits with hot coffee and chocolate treats, while discovering new sounds, still beats shovelling snow by a wide margin.

I would disagree. It's extra fun to shovel up snow in a large high pile in order to make a snow shelter. Especially when you do it in your backyard and not by necessity in the wild. And then after waiting an hour or more, or even a day, more snow shoveling to carve out the inside to make a nice shelter where one can sleep the night. This year I'm fancy and will use actual marked wood sticks cut on the table saw to poke into the snow pile so that when digging from the inside the wanted thickness of the walls is observed.

You see, snow can be fun.

[mevla]

I'd love to know if the static linking of the plugins made anything worse for anyone?

I'm afraid, as much as I've reported about everything working nicely in Mint, I will not be testing the latest build. The mention of the fonts being not so right is not appealing for a setup that works fine. But then, knowing if it still works on a system might not be a priority regarding all the other systems where it does not work well. Thanks for all the work ! I'll be testing a later version when the font problem is corrected or when the version is said to be stable.

[lunardigs]

Hello guys,
Next version to try: http://uhedownloads.heckmannaudiogmb.ne ... 821.tar.gz

Remember it is a testing build, not a production one.

Many thanks

This is the first one that's broken for me. Basically, the GUI is un-alterable with my mouse. I see blinking lights, etc., but I can't edit any parameters. Moreover, the VST3 version doesn't render the GUI at all; it just looks like a blank window frame with nothing inside--in fact, it's transparent.

I'll explore some more and report further.

Btw, no matter what, thanks for the new build!

Okay, quick update: I've upgraded from Fedora 26 to 27. I have all XCB packages available from official and RPMFUSION repositories installed (libxb 1.12-5 and xcb-util 0.4.0-8). Running Bitwig 2.2.3, Repro 6824.

Result: GUIs of VST2 intermittently work; if I load the plugin and wait for a minute, I can twist knobs and GUI responds; if I press a button, it responds. However, if I twist knobs then push a button it stops responding--seemingly from having pushed a button. To make responsive again I can change windows (switch tasks) then return to DAW and plugin is responsive again. This can be repeated again and again for me. Moreover, when GUI is responsive it's somewhat slow and inconsistent to mouse inputs.
VST3 GUI doesn't appear at all, but plugin generates sound and can be played.
All plugin controls can be changed via hardware controller or Bitwig remote controls (and is effected on-screen). Sound generated is fine.

That's it for now. I'll attempt more later.

Thanks, abique!

[Jack Winter]

Hi abique,

I'm sorry I've been quite moronic and confused testing this, but I think I have something interesting to report. The system is Archlinux with libxcb 1.12 and xcb-util 0.4.0.

I removed all traces of Repro 1/2 in ~/.u-he, then installed Repro-1-6824.

The result in Reaper is the same as previously reported, namely a grey window and the repeating xcb messages about BadDrawable:

Now for the interesting part, I tried with Ardour 5.12 and it works...

Looks like it conflicts with reaper in some manner and not really with xcb-util 0.4.0.

Please let me know if you would like me to do any further tests on my system or on Reaper/libSwell.so, or if there is anything else I can do from my side.

Would possibly be very helpful if the Reaper users experiencing grey windows would test with Ardour on their systems, but to me it looks like a linking conflict between Reaper and Repro..

Unintended duplicate post :S

[OldFuzzface]

I'd love to know if the static linking of the plugins made anything worse for anyone?

well here is an update with 6824 from Arch, 4.14.8, Bitwig 2.2.3:

VST2: laggy, but better as before, still not really usable.
VST3: no dice, empty window.

cheers ...

EDIT: tell me if you want to see logs.

[glokraw]

...sigh...but cheer up, glokraw, picking nits with hot coffee and chocolate treats, while discovering new sounds, still beats shovelling snow by a wide margin.

I would disagree. It's extra fun to shovel up snow in a large high pile in order to make a snow shelter. Especially when you do it in your backyard and not by necessity in the wild. And then after waiting an hour or more, or even a day, more snow shoveling to carve out the inside to make a nice shelter where one can sleep the night. This year I'm fancy and will use actual marked wood sticks cut on the table saw to poke into the snow pile so that when digging from the inside the wanted thickness of the walls is observed.

You see, snow can be fun.

I happily stand corrected. I'll bet you could do
some serious overclocking in your winter palace!
One year, a blizzard placed a huge drift
on the lee side of a six foot cyclone fence, and we tunneled out
a nice fort inside. Quite cozy for the first half-hour or so...

Thanks for the irq tips, makes a nice addition to my textVIP folder.

[glokraw]

Glokraw, the previous build also did work for you right?

Yes, R5 and R1 were OK in the previous 6640 release.
Cheers

[glokraw]

Would possibly be very helpful if the Reaper users experiencing grey windows would test with Ardour on their systems, but to me it looks like a linking conflict between Reaper and Repro..

I get the grey window in reaper, but it's OK in Mixbus, AKA the frilly Ardour

The gui lags I mentioned in Bitwig are also present in Mixbus

I also tried the windows versions of R5 and R1 in windows version of reaper,
in wine, no lags, no gui issues...

and this is in pclinuxos,
kernel 4.12 with
official nvidia driver
pcie nvidia 9400 video card
intel mobo with i7

Cheers

[krans]

The grey window in Reaper does by the way sound very similar to the empty, grey window I get in Qtractor.

[abique]

You could bug report to QTractor that it needs to call effIdle() from the main thread, maybe at 60 fps?

[mclstr]

We used to always duplicate everything in a way that you could switch over to the alternate setup when something failed.
We would only get a momentary glitch that way and not have to stop to fix anything.

Smart!
If someone knows a clever way of doing this with Jack and a Linux setup, please let me know.

A simplified version is:
Duplicate everything on two separate laptops with enough software variation that they won't crash simultaneously. These could be plugged into an analog mixer(another source of failure). Or just plug and unplug in a failure.
Sync the two laptops via timecode or just start and stop both at the same time.
