Decent Sampler closes Ardour instantly

Same here, but with a workaround.
If I create a MIDI track without a plugin (i.e. I select “-none-” in the Instrument dropdown) and then add DS, it works.

If I select DS within the Add Track/Bus/VCA dialog or if try to replace a plugin in an existing track, it crashes.

There’s a new version of DecentSampler .(1.12.6) … I tested the statically built VST3 here and it worked without any issues.

I can no longer login to the DS bug tracker so it would be great if someone else could confirm the fix and then let Dave Hilowitz know.

Hi Paul, I’ve let David dhilowitz know on bug tracker that at least in my case both work.

I’ve tried both versions

Decent Sampler v1.12.6 Linux (x86_64 - Static build)
Decent Sampler v1.12.6 Linux (x86_64 - Dynamic build)

on Ardour 8.10.0 “Sonora Portraits”(rev 8.10)
and both work without any apparent problem, on my system
which is the following:

Operating System: Ubuntu Studio 24.04
KDE Plasma Version: 5.27.11
KDE Frameworks Version: 5.115.0
Qt Version: 5.15.13
Kernel Version: 6.8.0-49-lowlatency (64-bit)
Graphics Platform: X11

Regards

Any plugin which loads dynamic libraries is just waiting for trouble. If you use pre-built Ardour (rather than distribution version) eventually the distribution library version and Ardour library version will differ and you can get crashes again. If you always use the distribution build of Ardour then presumably that isn’t a problem because the distribution Ardour and the plugin will both be using the distribution library.

Hi Chris ccaudle, I’m not a programmer, but I’ve read something about it in previous versions of both Ardour and decentsampler, and I’ll follow your recommendation to use the static version, since Paul has commented that he has tried the static version and hasn’t commented anything about the dynamic version, I understand that it’s better to use the static one.

Since decentsampler has been giving problems lately, I’ve been testing it as both Ardour and decentsampler were updated and that’s the reason for having several versions of decentsampler installed, but if the “correct” and stable thing to do is to use the static one, I’ll do so.

That might explain some of the instability “crashes” of ardour in projects made with previous versions of both Ardour and the sampler.

In short, one version that works well is enough.

greetings

I am writing you to report a current problem with my Linux based music making setup: Ubuntu Studio (26.04), Ardour (9.7.0) and DecentSampler (1.23.5). Nothing new under the sun since there has been similar issues over the years but this is what I have experienced during this week:

Ardour crashes instantly every time I start to open an old project including DecentSampler tracks or working with a new Ardour project when adding DS track there. My other Ardour projects without DS work perfectly well so I am pretty sure this issue is somehow related to DS. I have also tried both static and dynamic version but the problem remains the same… Any other users can confirm this?

I just send an email about this topic to DecentSampler but I though you might want to know about this case here in Ardour forum as well.

Thanks to your request (I’d been wanting to do this for a while), I installed DecentSampler 1.23.5, loaded a string library onto the MIDI track, and played it back; everything is working as it should. However, I’m running everything on AVLinux.
Maybe it’s because of Ubuntu?!

Hello, decentsampler is a bit temperamental software, it usually gives problems when you open the brouser, searching for libraries sometimes at the beginning of putting it on a track can cause ardour to close, sometimes.

I have been using decensampler since almost its first version and sometimes it has caused problems, now I have version 1.23.5, and it works in both Ardour 9.5.0 and 9.7.0 (since I am transferring some projects from one version to the other).

When you have problems with decent, it is best to contact the developer Dave Hilowitz (Contact - decent|SAMPLES), he is also on patreon https://www.patreon.com/messages/2382136-118226605?mode=user&tab=direct-messages.

Page with all versions of decentsampler: https://store.decentsamples.com/downloads/decent-sampler/versions

A problem that I pointed out to Dave Hilowitz is that all versions are called the same (DecentSampler.so), regardless of the version, that is why when installing a new version of decensamplar it will tell you that you already had one installed and that if you want to install the new one, the old one will be overwritten…

If you want to have more than one different version of decentsampler installed, because for example you have old projects that used a previous version of decentsampler, what you have to do is the following:

Create a folder separate from the one that ardour, reaper or other DAWS use, only to decensamplar and in it each version that you download, in its own folder that has the name and version number and it is those folders that from ardour you must add as a plugins folder apart from the ones that ardour looks for by default.

That way you can use several versions of decentsampler at the same time.

In any case, it is advisable to finish a project in the version you created it, before moving it to a new version of ardour.

If you still want to transfer a project created in one version of Ardour to another more modern version, it can be done with some precautions.

1.Check and note the plugin versions of the project you want to move from a new ardour.

2.Make sure that both versions of ardour are using the same plugin folders.

3.Try to use different folders/directories for each version of ardour.

4.Open in (for example ardour 9.7.0)(the project created for example in ardour 9.5.0) and save it from ardour 9.7.0 in the ardour 9.7.0 directory and from then on you are working with a copy, without modifying what you already had, in case you need to recover something again.

  1. I recommend sticking to LTS versions if you use Ubuntustudio, but if you use intermediate versions and it works for you, there would be no need for the LTS version, I am on version 24.04 lts, ​​but I am waiting until from August it can be updated directly to 26.04 lts, ​​let’s see how it goes.

greetings
