I see on the website that PadMu products have Hardware based upon Onyx Boox Max series. Which are the main differences between them ? 

Yes, you are right, our PadMu Hardware is based upon Onyx Max.

Here are the main differences:

first of all our SW is optimized for fast music page turning and also we have:

  • music library management
  • import pdf files from Dropbox, Gdrive
  • concert list, you can set up list of pieces to perform on stage
  • page sequence, you can play pages in the order you prefer also you can play more than once the same page
  • double configuration (also in landscape mode, excellent for organists)
  • three different modes to turn pages in double configuration

Also you can switch between the two desktops, ONyx and PadMu and choose the one you prefer
