Original Post

Dear Polyend Support,

I would like to report a critical issue I encountered on my Polyend Tracker Plus.

After creating a project using various samples and saving it, I later reopened the same project and found that all samples except for the bass sound had been completely deleted. I did not manually delete any samples myself. The bass sample was still present, but all other samples were missing from both the pattern and the sample loader.

Even reloading the project multiple times does not bring them back.

I’m using the latest firmware as of 2025/05/25 JP Current Ver 1.0.3
The samples were originally loaded from the SD card and not recorded using the internal recorder.

Could you please investigate whether this is a known issue, or advise if there are any hidden conditions under which samples may be automatically removed?

This behavior has caused a serious loss of work and I’d appreciate any explanation or recovery suggestions.

Best regards,
OKSproject

Hey there @oksproject2107, thanks for the report. I’ve moved your topic to a Bug report. Is there any chance you could attach a .zip of your project that is giving you issues along with the samples that are not loading? I’d be happy to give it a look.

Thank you for your response.

Yes, I’ll prepare a zip file containing the project and all related samples that are not loading. I’ll send it to you shortly.

Just to clarify: the samples I used were not imported externally. They were included by default on the Tracker Plus — specifically from the internal sample folder located at E:\Samples\Stereo Samples\Trap.

Please let me know if there’s a specific email address or upload link you prefer I use.

Best regards,
OKSproject

Got it, thanks! If you’re using included samples, then I’ll start with those on my unit and if I’m unable to reproduce, I may ask that you share them just to see if anything happened to them.

I will also alter your original post just so it goes with the Bug template, but rest assured I will keep every word you wrote intact :slight_smile:

Could you also provide the following information;
The Build Version of your firmware
Does it impact only this project or if new projects you create are also impacted

A quick analyse of the samples that are not saved within the pti shows that they are 24bit.
Would be nice to see if the bass sample is 16bit.

Thanks for the follow-up!

I just checked, and the bass sample is also 24bit — same as the others.

So it looks like the bit depth might not be the cause.

Let me know if I can help test anything else.

Best regards,
OKS

Sure！ here’s the information you requested:

Current Version: 1.0.3

So far, this issue has only occurred in this specific project.
I’ve been working on other projects for several tens of minutes and haven’t encountered the same problem elsewhere.

Please let me know if you need anything else.
