  • Hi Antonis,

    Thanks for posting. 

    if you're experiencing a "USB drive error", your thumb drive is likely not properly formatted for use with the Crimson module. Keep in mind that your SD card cannot exceed 32GB in size. Additionally, any audio files that may be on your thumb drive must be located on the root directory of the card and not in any folders. The maximum number of files that can be located in the root directory is 512. The samples files must be 16-bit, mono or stereo .WAV files with a sample rate of 48K, 44.1K, 32K, 22.05K, or 11.025K.
    • The .WAV file must be located in the root (main) directory of the card and not in any folders.
    • We recommend formatting your SD card to a FAT32 file system (if it is not already) and naming your sample files according to this format. Basically, this means:
      • Do not use these characters: " * / \ : < > ? |
      • Do not use spaces.
      • Limit your file name to 8 characters (excluding the file extension, ".WAV").
    • You can assign up to 48 MB worth of samples per kit (the sample library on your SD card can be larger, of course). Also, please note that a sample's size will be rounded up when loaded (e.g., a 2.1 MB sample on the SD card will be treated as a 3 MB sample when it is assigned to a pad).
    • The max number of files that can be located in the root directory is 512.

    I hope this helps! Let me know if you have any additional questions.
