How do I turn on Legato Glide Mode on the Matriarch?

Legato Glide only produces the Glide effect when a new note is played while the previous note is still held down on the keyboard.

To turn Legato Glide On, continue to press the [SHIFT] button while turning the GLIDE knob to the right. To turn Legato Glide Off, continue to press the [SHIFT] button while turning the GLIDE knob to the left. The Default setting for Legato Glide is Off.
