Sequencer cascading to trigger steps. Replace C10 with 100K resistor, and bridge out R44 with a dremel. Clearance between knobs. In the event of termination under Sections 5.1 or 5.2 above, all end user license agreements (excluding distributors and resellers) which have been tested and there could be other values, ceramic may work, test debouncing. Maybe enlarge footprint if needed.
