Sequence like a telephone operator for greater connectivity.
Instead of using buttons to sequence when a trigger pulse should exit a jack, this sequencer sends its triggers directly out at each of four beats or any of its subdivisions for eighths, sixteenths, and triplets. The advantage to replacing buttons with direct trigger output jacks is that it can control multiple devices without them having to always do the same thing (same lane would mean same rhythm), that it’s easier to mix and match triplet and traditional subdivisions, that you can shift-click to move a whole mass of wires from one jack to another (to rearrange the rhythm of everything at once), and also that you can individually process the trigger outputs (per step!) to add repeats, inject random delays, make decisions about when they should pass through, and so on.
The sequencer is activated by a gate input (center) that either resumes from where it left of (pause mode) or begins at the beginning each time (restart mode). The Midi Drum Trigger is a great way to coordinate multiple sequencers being activated by various notes on the keyboard, but also the sequencers can be sequenced by other sequencers that have gate outputs or they can sort of always tag along whenever a given gated signal is on (or perhaps an LFO).
Use multiple copies of the sequencer on the same device while they are set to different BPMs (usually some simple ratio) for polyrhythms or set them to the same BPM for variable additions, where one sequencer adds some extra notes whenever it is turned on. Multiple sequencers can be also be switched on at different times using the gate inputs to mix up various rhythms and to build up songs, starting at various places within a measure, and so on.
