Actually I don't know where the change~ object is from - I've nver seen t
before. I would just use biquad~ 0 0 1 -1 0 (assuming that change~ simply
ubtracts the previous sample from teh current one as I guessed from the patch :)

ok tried to upsample the whole thing (after the osc~) and now change~ does
nothing anymore… it just spits out the same square wave i feed in…clues?

crosspost! sorry about the noise. thanks for the inputs i will try to to this.
not sure if i can. otherwise i will ask back if that’s ok!

so if i would measure at the peak of the sawtooth and would upsample inside the
pd patch, i would get higher resolution, right?
any ideas how i can measure at the peak? (using the rpole output on both
samphold inputs does not work and delaying one of them is also not working)

Sorry for the double answer, but this also occurs to me:
To improve accuracy, measure both halves of the cycle and add them.
To improve further, upsample the whole mess, say by a factor of 16.
Doint both of those would improve the theoretical resolution by
a factor of 32. (Of course, you still ha
That is an excellent, witty way to measure pulse withs using
only tilde obects - my hat's off to you.
The methond only has limited accuracy since its measurement is in
samples. For instance, a 1/2 cycle of a 440-hz. tone at 44.1 kHz is
only 50 samples, so there's only 2% accuracy. That's about
dear list,
i have a strange problem with my “sinetosawtooth” patch.
it is basically a version of the pitch to voltage conversion used in the old
gr300 guitar synths from roland.
i cut out all the clutter to make it easier to look at and understand. (cut out
the adaptive filtering at the input
