Hi Thomas,
HIGH and LOW refer to the binary state. The square wave conversion using
[~ 0.5] will actually give him a square triggered at the mid point of
the sawtooth wave, not the beginning or end, so the phase of the square
would be 180 degrees off from the saw. I suggested to use [==~ 1]
Hi Derek!
Your approch is exactly what I need!
I didn't know the [==~] and [avg~] objects, but they make exactly what I
want.
Thanks for the suggestion!
Saludos!

Hi Raul,

you could just make a phasor at the rate of the square wave, and use

Thanks a lot for your suggestions!
I tried to make the mathematical comparation for phasor with [==~] and
[avg~] and then a counter in order to count phasor cycles.
But it doesn't work, it only count one. Did I make something wrong?
Attached is the example patch.

hi raul
i am still unsure about your initial problem. probably the solution is
quite simple, but maybe you need to provide some more information. would
you like to use the rectangular wave to mask the phasor wave? so that
your resulting wave would look like this :

Hi,
[s-totalrecall] is a gopified wrapper for qlist. Place [s-tr-node] in

Hi Roman!
I'm sorry for my lack of information...
I'm making a pulsar granular synthesis patch based on Curtis Roads's
Microsound ideas using a patch from nullpointer (
http://www.nullpointer.co.uk/-/pd.htm).
So, the phasor is my pulsar frequency reference, and I want to mask the

Hi Roman, list!
Attached is my aproach to generate masked-phasor, as suggested.
But in this way I can only obtain 1 of N phasor cycles.
How could I obtain a phasor with a M:N cycles relation, like that (2:2):

This won't work, because the phasor~ may reach 1 in between samples. In
general, phasor~ is
