Boss2 with Moode - Can't see all my music files

[Lorenzo7.n]

I've just bought a Boss2 (RPi4 2Gb) with Moode but I cannot manage to see my music database, at least the greatest part of it.

I first tried connecting a NAS disk (about 2-3 Tb of music files) but the music library generation process in Moode was very slow and after several hours and different trials I was able to see only very few files. Then I tried connecting the disk through the USB port. In this way I managed to see more file but anyhow just a very very small fraction of the database. The library generation process seems to never come to an end even after many hours.

Is there any limitation in Moode related to the number of files that the database can handle? Is there any config parameter that I have to set?

Thanks!
