[qlist] is a Pd object that I haven't tried before, and it will do exactly what I need (I hope and assume, as the help file has assured me as such).
Instead of "looping," I'm going to record a series of events in this [qlist] object, and establish that that is a thing, a duration of time, a measure, or whatever. It's not playing back audio, but more like making a little MIDI file, and playing it back, but without the crappy sound baggage. What I mean to say is that I'm recording the relative timing between me pressing this pedal, turning this knob, and saying this thing, and it will remember and repeat (and repeat and repeat if I want).
Let's see if it works!
