Firmware updates and patch/sequence library management are accomplished via DISK MODE. To enter DISK MODE: 

  • Power off Muse. 
  • Connect your computer to the USB-B port on the rear of Muse. 
  • Hold down the SELECT encoder on Muse and continue holding it down while powering on Muse. You may release the SELECT encoder once the PROGRAMMER screen reads DISK MODE.
    !!! NOTE: Windows users may see a prompt that says, “There is a problem with this drive, scan the drive now to fix it.” Do not scan the drive as this may cause issues with your unit and will likely result in having to send it back for service. Either exit out of the pop-up prompt or wait a few moments and it will go away on its own. 
  • Muse will now appear on your computer as an external disk named MOOG_MUSE.
  • Once in disk mode, you may open the MOOG_MUSE disk to view its contents. 
  • firmware contains the firmware binary file 
  • library contains data for all patches and all sequences 
  • util contains calibration data and should be ignored

To make firmware updates, drag the updated firmware file (named “moog-muse-firmware.bin”) into the firmware folder, replacing the old file. The firmware folder MUST contain ONLY a valid “moog-muse-firmware.bin” file and nothing else for Muse to function properly. Once the firmware file has been updated: 

  • Eject the MOOG_MUSE drive from your computer. IMPORTANT: Safely ejecting Muse is critical to ensure all pending operations are completed and that the firmware is fully updated. 
  • The PROGRAMMER screen will now read DISK MODE SESSION ENDED. 

You’re done! You may now power off Muse, disconnect it from the computer, and power it on as normal to begin using the new firmware. 

The library folder contains a folder for every patch bank of Muse. Within each bank folder is a separate folder for each patch - inside of which is the patch data for that bank and patch location. Only one patch can be in a patch folder at a time. Inside the sequences folder is a similar file structure for the banks and sequences in the SEQUENCER. You may move around patches/sequences, rename them, back them up on your computer, and transfer new patches from your computer to Muse using DISK MODE, but you must retain the file structure in the library folder.
