In my explorations of others’ work, I’ve noticed that a lot of people seem to use a quantized phasor~ coupled with an edge detector to generate timed bangs instead of using a metro object. Is there some advantage to this? In theory I suppose an audio-rate edge detector could be 44 times more accurate at 44.1KHz than a metro refreshing every 1ms, but being off by at most 1 ms doesn’t seem all that bad to me, so I feel like I might be missing something.

Can anyone offer any insight into best practices for generating a solid timing signal? Thanks!

If you use phasor~ and have Overdrive on, the timing should be rock-solid, at the occasional expense of drawing etc. So it’s not just 44 times as accurate, it also doesn’t drift… you can at first be off by 1 msec, but eventually you could be off by a lot more, by design.

Definitely use the audio objects for timing if your needs are precise.
