On SX900, to change all your 4 Multi Pad buttons in OTS Link mode:
1. Set up your OTS Style for your song (orange box on display screen).
2. Tap Grey" Multi Pad box on display screen.
3. Select your new Multi Pad from the list now on screen.
4. Press "Exit" button to go back to main display screen.
5. Press "Freeze" and "Memory" buttons together, then press "Select" button on the Multi Pad Panel.
Screen will go back to the Multi pad screen you were already at, so just press "exit" again.
Now all the new 4 multi pad buttons will work during your performance.
If you want a multi pad from your USB stick, you must tap "User" on the top of the Multi pad list screen, then USB to take you to your USB list. Select you Multi Pad and go to #4 above. To undo and go back to factory setting, press "Freeze" button. I like this better than saving everything to the registrations, unless it is a favorite song I want to keep.
