PLAYMID.BAS and MIDI file.

[a740g]

The program is great.
Only as a MIDI payer alone does it work very well.
I'm very happy about that.

I also have a lot of MOD sound files, but I can't find any way to include them in my programs.
Which is actually a shame because they are very small and contain good sound.

Thank you! 

Well, you are in for a treat.

If the files are just AMIGA Protracker compatible MODs then you can try a740g/QB64-MOD-Player: A ProTracker (and compatible) MOD player & library written in QB64 (github.com)
If you've got S3M, XM & IT then try a740g/QB64-LibXMPLite: LibXMP Player and Library for QB64 (github.com)
The second one is based off a similar library by RhoSigma you can find here: https://staging.qb64phoenix.com/showthread.php?tid=29

Thank you for your prompt reply
The first MOD Player is already very good and I like it.
I would like the second ( LIBXMP Player ) better but it causes a compiler error for me.
The attached EXE runs great.
At the moment I just can't find the error why it isn't compiled.
Tried it with QB64PE 0.8.2 and QB64 2.0.2 in 64 bit but it always crashes with an error.

From the screenshots you have shared, it seems like QB64 cannot file the required files.
Assuming you have extracted the files to its own folder, open QB64 (latest x64 version) and then ensure "Run > Output EXE to Source Folder" is checked. Then load XMPlayer.bas and compiler. You can also download the files again from GitHub. I've submitted some new changes.
