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
