If you're a subscriber to this blog, thank you. This is almost certainly not interesting for you.

If you're the owner of a Roland FR-4x digital accordion and trying to find which USB sticks can be used with your accordion I tried out every stick in my house with no luck. I learned:

  1. They need to be FAT32 (not ExFat)
  2. They need to be USB2.0
  3. 16GB seems to be the ideal size? there's some reports of other sizes working.
  4. Not every usb drive that meets these criteria work 🥴

I can attest that these PNY 16GB Attaché 3 USB 2.0 Flash Drive work.
