Right...ratcheting is a rapid repetition of a single stage's voltage settings, generally at some fraction of the main clock pulse. Although, I will point out that while that Koma Komplex is a rather spendy device, it has a lot of possible control routings that can give you this result along with many others...particularly if you have a Boolean logic module (or two) in your build. Also, modules such as comparators can be used to output controlling gates in conjunction with using a sequencer row for timing CVs. Given enough logic, clock counters, dividers and multipliers, extra gate/trig sequencers and comparators, you can make even a fairly simple sequencer turn backflips.
