USB stick problems

Hello,
This is a noob question, but what do I need to do with a USB-stick with samples in terms of formatting etc to get it to work? I got the samperboxworking fine, I can play the default sound with a usb-midi keyboard, no problem. I've tried just taking a thumb drive and adding directories with samples named /0 Somethingorother/, /1 Somethingelse/, etc, but to no avail. I'm really shit at this, so please use small words. I'm on a Raspberry Pi B original.

Thanks in advance for any insights.

Jakob

Oh, and by the way, I'm a mac user (through no fault of my own, mind you).

How are your samples filenames named? And are you using an (optional) definition.txt file?

I've been using the sample folders downloadable from samplerbox.com, just to try to make it work first. The Mellotron sample is named 343_G2, 3444_G#2, etc. One of the Poly 61 sample directories contains files named just c1, c2, etc. In that folder there's a definition.txt (what is that, anyway?). I also found this bit of info: "the samplerbox build doesn't like GUID Partitioning Scheme. It detects a disk, and tries to mount it, but the mount point is empty. This means, on a Mac you can't use the GUI application "Disk Utility" to make your FAT32 disk, you need to do it via the command line." Might that be the problem?

Thanks a bunch for answering.

Update: I've formatted the thumb drive from the terminal. Still nothing.

The definition.txt file is described at point 6) in the FAQ: http://www.samplerbox.org/faq

What kind of MIDI keyboard are you using? The Mellotron samples start from G2, so if it's a small keyboard maybe you have to set the octave higher on your keyboard to reach the samples.

I wouldn't have thought your USB disk format would be an issue - but I can't test it myself (Windows)

Thanks for answering again. I've a Keystation mini 32, and I'm in the C3 octave, so that shouldn't be an issue. The Mellotron sample pack aldready has a definition.txt, so that shouldn't be it either. I read somewhere that the Pi sometimes doesn't work with old and/or crappy thumb drives, so I might try to buy a couple of new ones and see what happens. But that really feels like a hail mary...

Have you named your Mellotron folder "0 Mellotron"? If so, does the "0 Saw" sample-set work on your USB drive?

Hi again and thanks for your patience and help. I went and bought a couple of thumb drives this morning and did exactly what I did with the old one. AND IT WORKS NOW. (It's a 8GB Kingston DataTraveler 50, in case someone has the same problem as me.) Hell yeah!

Thanks for the update! What make was your old one?

It was an old Sandisk Cruzer. I think the problem might have been the pesky U3 virtual drive. Tried to uninstall it from a friend's PC (the U3 software is, of course, not Mac compatible), but the uninstaller broke down repeatedly. Might just have been that the thumb drive was way old, abused and corrupted...
