akai mpx8 main3The MPX8 comes with free drum, percussion, and loop sample content.  You can also load your own samples to the SD card.  The following article will cover the requirements needed when preparing your own sample content.





When using samples with the MPX8: 

  • The sample files must be 16-bit, mono or stereo .WAVs. They can have a sample rate of 48, 44.1, 32, 22.05, or 11.205 KHz
  • The sample files must be located in the root (main) directory of the card and not in any subdirectories.
    512 files can be stored in the root directory of the card.
  • Use an SD card or SDHC card with a capacity no larger than 32 GB.
  • Format the SD card to a FAT32 file system (if it is not already).
  • Name your files according to this format: 
    -Do not use any of these characters: " * / \ : < > ? | 
    -Do not use spaces. 
    -Limit your file name to 8 characters, if possible. 

You can assign up to 30 MB's worth of samples onto MPX8's pads at a time (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).


My sample still does not read using the above specifications, what's wrong?

Some files may have extra data attached to them when being exported from a DAW/Recording software, such as a session's time stamp.  This is not something you will see by looking at the file.  To get rid of all extra data on a .WAV, you can use Audacity to re-save the file.

In Audacity:
  1. Select File > Import > Audio to bring the file into Audacity.

  2. Audacity will ask you if you want to make a copy or read the file directly.  If you want to preserve the orignal sample choose make a copy, if you want to overwrite the sample choose read the file directly.  Select OK after choosing your import method.

    Leave all sections blank and select OK

    You file is now re-saved and ready to be added to your SD card.
