Samplv1 inside Ardour, keep sample ?

Hello guys, first time here...
Coming from Lmms I was serching for a Fileprocessor alternative. Samplv1 is what I was looking for but there's a big issue: everytime I open a project, I need to reload the sample (sample or preset is the same)! It's a pain. So, am I doing something wrong ? Not very useable in this way..

yes, your probably doing or having something doing wrong in there :)
it sure is not supposed to ask for a sample file every time you open an existing and previously saved Ardour session whatsoever.
ps. which versions of either ardour and samplv1?

I tried several times with no success..
Opensuse TW, Ardour from multimedia repo and Samplv1 is your package from sourceforge ;)

just to be on same page, all qstuff is first developed here under openSUSE TW :)
there are no excuses why you can't tell about exact versions: latest public ardour5 is v5.12 (dunno how you got it, there's no package from TW whatever); samplv1 should be v0.9.3--please don't go with anything less.
also make sure you read and comply with these words of advice for Ardour users...--not specifically to your issues (probably not at all) but one never knows ;)

Sorry this is the list:

For Ardour:
Information for package ardour:
Repository : multimedia:apps
Name : ardour
Version : 5.12.0-2.18
Arch : x86_64
Vendor : obs://
Installed Size : 43.6 MiB
Installed : Yes
Status : up-to-date
Source package : ardour-5.12.0-2.18.src
Summary : Multichannel Digital Audio Workstation

And yes, I've fixed all lv2 files for samplv1, synthv1, etc, etc..

Side question: Is it normal that I need to fill the subject field when I reply to your post ?

as a matter of fact, i now realize that the last release version for samplv1.lv2 is broken in the exact regard to what you report: the sample file is not being save as LV2 plugin state whatsoever :/

you were right all this time, sorry for the pain I might have inflicted to you.

I'll investigate this further and come with a fix ASAP.

meanwhile the previous released version (v0.9.2) seems to be working right. Maybe you (and everybody else) will be better off falling back to it.

cheers && sorry for all the inconvenience

ps. the nasty bug is now fixed on git head master (samplv1 >= thanks again.

0.9.2 ardour crashes :(
Downgraded to 0.9.2, Ardour crashes on load.
Upgrade to 0.9.3.. still crashes on load !
So opened a session without samplev1, fine then I was able to open a session with samplev1.
Removed the plugin, save & close.
Downgrade again to 0.9.2 but now as soon I add samplev1 to a track, Ardour crashes :(
So, 0.9.2 (your rpm) does not work here.

please remember to read thewords of advice for Ardour users...;
while it's been said for "drumkv1" you ought to apply it to "samplv1" as same.


ps. re. side question: yes, you have to fill the subject line; if left blank it's filled with comment body first line, or something like that.

samplv1 v0.9.4 has been released and it includes the fix to this issue.

cheers && thanks

Installed, it's ok, Thanks for the quick fix ! Keep it up !

Hello, here again...
Ardour project with several samplv1 tracks. I reopened the project few time without issue but today, after a zypper dup and reboot, all samples are lost :(
Ardour and samplv1 are still at same version (not affected by upgrade) ardour-5.12, samplv1-0.9.4.
Is there a way to recover ? Where is the sample name/file saved ?

i am terribly sorry to hear that!

please do not hit save in ardour before the issue is possibly solved... try to use "save as..." instead (if ardour supports it).

sample file references are stored as part of LV2 plugins parameters state, so it's kind of not-human-readable...
you can however look into audour's session directory or folder for respective symlinks: each sample file is referred to by a symlink to each and actual file location in your file-system, stored outside the ardour session directory; also check if the sample files are still there or moved away somehow;

i'm afraid that's how far i can help you at this time.
hope you find your way through it all


HI, I reopened a project made with Ardour 2 years ago with few instance of samplv1. All samples gone :( For sure they are in the same place.

my deeply apologies for that happening again, but may I ask what really changed since last time you reported the issue, 6 years ago?

here doing tests with ardour8.6 and samplv1 0.9.90+ and nothing of the sort you tell comes around.

am I the only one?

Well.. It doesn't happens all the time. Probably ther's no logic in this but it seems that it happens reopening old project.
