The AN1X filter can be modulated by LFO 1. Go to the LFO section,
change LFO to a square wave and set the speed to taste. Then go to the
filter section and set the amount you want the filter modulated. Try
negative amounts as well as positive amounts.

Or set the ribbon controller X value to filter and tap the ribbon
controller. Tapping the ribbon will give you the staccato filter change
like a square wave but it's easier to get the filter synched up to
tempo.
