Is it in any way possible to send samples within an MMPZ?

[Douglas]

There are some songs I made that have some audio samples that don't come with LMMS, and I want to share them (the songs, with the samples) on lmms.io/lsp. Any way I can go about this?

Unfortunately, no
It is planned to add a new way of export, but not scheduled
Currently you will have to add the mmpz/mmp to a zipfile with the samples, and share that.
