The LATCH button allows you to toggle LATCH ON / OFF for the selected Arpeggiator pattern.
When LATCH is enabled, the Arpeggiator pattern will continue to play, even if the notes are released. If you are already holding notes when you enable LATCH, the pattern will be latched. Any latched pattern will stop when either the switch is toggled OFF, you replay the notes, or as soon as the host transport stops.
