I am new owner of Pa 900. For sure I will have some questions for starting and to familiarize with this great keyboard.
I want to assign one the Assignable button (1,2,3) to Quarter Tone.
Here is how I do it:
I go to Menu > Pads Assign Switch > Switch tab > Switch 1 > Quarter Tone > Write to first Performance.
Problem:
The Quarter Tone is not available with the Assignable button after restarting (turn off/on) the keyboard. That means the Assignable button turns back to OFF position.
I tried the same setup with others like Ritardando, Accelerando without success. I precise that I tested with all three Assignable (1,2,3)buttons.
Some screen shots of my setup:



Thanks for any help or advice.
