This is a basic ratcheting demo, featuring M564, Q119 and MOTM-730 modules.
Sequencer ratcheting was used prominently in early Tangerine Dream and other synth music.
This is an example of sequencer ‘ratching’ . . . at least from what I understand it to be. Even though you can’t see it in the video, the Synth Tech MOTM-730 plays a critical role role in the patch, along with the Moon Modular M564 Sequntial Switch and the Synthesizers.com Q119 sequencer which are shown.
