Phasor clock
I have noticed that when using the phasor as a clocksource , it needs a negative offset befor going into the compare module and then the edge ~`
The phasor~ goes from 0 to 1 , but for some reason going into >~0 doesn't recognize the zero , which is why I need the offset .

Please post compressed patchers. They're easier to open.

why this works for click~ but not for phasor~ is one of the biggest mysteries in MSP world.
however, you can reach what you want by using an offset:
[phasor~ 1.]
[+~ 0.1]
[>~ 0.1]
[edge~]
now both(!) outputs of edge report a transition :)
the interesting thing is that using [==~ 0.] or [==~ 1.] also wont work, where [==~ 0.5] does. think about that.
but it is even more strange:
if you connect a click~ to edge~ you can convert a trigger to a bang just as expected.
and if you convert phase to trigger using
[delta~]
[!-~ 0.]
you get a proper click - which works for driving a sah~ in order to control another phasor~, just as with the click~ object.
but if you combine the two and do
[phasor~]
[delta~]
[!-~ 0.]
[edge~]
it still doesnt work.
:)
@roman
Is it so strange? Phasor may not or (likely) won't hit zero or one. Between floating point precision and 1/frequency, it moves from .995 to 0.0012 or something. You thus cannot catch the edge with ==~ 0 or ==~ 1.
Delta~ works.
Or maybe <~ epsilon, epsilon equals something like 1/512, depending what precision tick you need.
that´s right, you could use minor shift for the >, which is small enough not to cause a delay for some 1 ms (scheduler rate, edge isnt more accurate) - and then you dont need the + offset.
or you could use line~ instead of phasor~ :D
oh btw.
"Between floating point precision and 1/frequency, it moves from .995 to 0.0012 or something"
it actually starts at 0. and that is enough to get a signal which allows to detect "nonzero to zero" transitions.
that is why [+~ 0.1] [>~ 0.1] works.
the issue @ward ist seeing is something else: edge~ (and zerox~ for that matter) might output at scheduler rate, but of course poll values from audio only once per vector.
Thank for the answers guys , really helpfull and sorry for the code text pollution .
