Applies to the Launchkey Mini MK3
Holding down the arp button on the Launchkey Mini MK3 will cause the pads to display a menu to change the arp settings.
To begin with, this may seem like a lot of options without labels, but using the keys while holding the arp button you'll see the pads change. The keys are labelled with each arp setting and is a great way to navigate this menu.
