Interesting, I changed the USB drive for a VFAT one, that works ok (same as your picture).
But, that does not record MIDI because of illegal characters in the filename (that’s why I formatted it as HPFS).
I guess I will have to wait until ORAM 2507 with your fix for ticket 1416 is released…
Thanks!
Hans.
EDIT: It’s not the filesystem per se, another USB stick with NTFS works ok. It’s also not the size, another 64GB stick works ok.
But the combination of NTFS and a subdirectory that is not named sfz or SFZ on the drive will cause it to fail. And that also applies to 'System Volume Information', so if you add something on Windows, it wil subsequently fail.
Possibly the same applies to a VFAT drive, but I have not tested that.
If you only have one sfz directory for the soundfonts everything works, even with two USB drives. All other samples must remain in the root directory.
