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/
