Convert signal into bangs
Is there any good reason why edge~ is not creating bangs when the ramp from sync~ hits (or even crosses through) zero? Isn't this what edge~ is designed to do -- bang at transitions to and from zero?! I saw an old post where somebody did exactly this with an audio signal.
because, depending on the speed, it might not reach exactly 0.
what you can do for nonzero-to-zero-signal-to-bang is this:
phasor~
-~ 0.5
%~ 1.
+~ 0.5
edge~
this will then also work with various other objects - such as custom phasor-modificiation patches, the brandnew 8.3 externals and, of course, rate~, sync~, and line~ - and it will also work in older 32 bit systems which had even more (mostly unavoidable!) "issues" like that.
I got it to work like this:
damn, i should have opened max.
the % solution above is only the to-go solution for up to ~3000 bmp.
it could make sense if you have a - 0.5 % 1.0 phase somewhere running already anway.
the mathematically correct solution is this:
phasor~
delta~
<~ -0.5
edge~
this works up to nyquist.
andy´s solution work until 8000 bpm, its accuracy depends on the current vectorsize, and it reports twice instead of once^^
I think the Audio Interrupt and Overdrive settings might be important as well.
no wonder with zerox~ :)
(btw. in my phasor patches i am actually using <~ -0. - so that it theoretically works until samplingrate. but i recommend against this for a general purpose patch.)
Thanks, you two, this is all very helpful! So far I tried out Roman's second solution and it does work well with sync~ substituting for the phasor~.
