flies

I want to build an octave down effect in max msp, one which produces a pulse

wave for every 4 zero-crossings. (omitting DC) any audio wave will cross

zero two times, so in two periods it crosses 4 times. So the problem boils

down to counting zero crossings at sample-perfect timing.

my guess is that it will have something to do with +=~ feeding sah~ or

count~ or something, but i can't figure it out.

of course it's fairly trivial to simply pitch down any input by half, there

are very many ways of doing it, but this particular way interests me b/c it

This is how I achieved this... as dirty as possible!

sweet. For some reason i thought that zerox~ output a float, but this is

sweet.  For some reason i thought that zerox~ output a float, but this is
awesome.  ty :)


please don't do that, it doesn't get through to the forum.

can you post it as text? 
thanks

Isn't there a PerColate object that does this ? Weave~ ?? Not as much fun as building your own, of course...

I did send a picture of the patch. Sorry, I tried to help ;-)

There are times when the image is actually quite helpful (for 

instance, trying to demonstrate something that needs a variety of 

3POs, or for simple patches where rebuilding is more informative than 

mere Copy & Paste). But it is hard on the poor forum readers.

i agree, they should allow it on the forum too. how about the archives? does it get through there?

small optimization: i think if you just subtract 1 from the bitand~ output

then you can skip the selector and get the same output with a few fewer

signals tied up. (it'd be phase inverted as compared with the selector

but this totally sounds like teh shit. ty.
