Thanks everyone, super helpful.

@peter: it seems to me that `max~` and `min~` take signals in and put signals out. How would you use them to go from signal to event?

@liam: yes! `threshold~` is what i was looking for; i'm always up for doing the extra work to stick with vanilla.

@claude: deep. i'll look at the expr~ example, very helpful reference.

what are your favorite objects for going from signals to events?

specifically, i'd like to make a sample accurate / audio-driven
sequencer.

Note that signal-to-event in Pd's architecture necessarily means the events occur up to 1 DSP block later than intended, and possibly not scheduled on Pd's logical clock (I haven't checked the source of eg [threshold~] to see if it schedules with constant 1-block latency vs variable as-soon-as-possible on the next block boundary latency, but I suspect the latter). So you'll get late events with up to 1.5ms jitter, with default settings.

If you want a sample-accurate audio-driven sequencer, you really need to keep everything in the signal domain. See for example the 0xA expr~ tutorials at https://archive.bleu255.com/0xA/
