I would like, upon a control-message trigger, to generate a single-sample impulse.

This is generally useful, but the specific thing I'm trying to do right now is to use [rpole~ 1] as an integrator. I believe I can reset the integrator to 0 by momentarily setting the coefficient to 0 -- and, if I can get a single-sample impulse, then the coefficient is just 1 - trigger_impulse.

This functions just about well enough for the purpose of resetting an integrator -- but I'm still curious how to get an impulse.

Thanks!

@ddw_music Is this what you had in mind?
dirac impulse.pd
But if you're just trying to clear the integrator, send a [set 0( message to the left input.

All good suggestions, thanks!

And with object [step~] from zexy library.

Impulse.pd

@paresys zexy also had / has? a specific executable named [dirac~].......

@whale-av Yes. I had not seen the dirac object.
[step~] and [dirac~] are present in zexy-v0-0extended and in the last version: zexy[v2.3.0]
