momentary or toggle modes. When [TIME
DIVISION] has been activated, these 4
buttons are used to set the time division of
the Arpeggiator and Note Repeat features.
12. [CONTROL BANK] – The MPK25 features 2
independent banks of continuous controllers.
Effectively, this allows you to control up to 32

banks. The LEDs above the button will
reflect the currently selected control bank.
