katja,
you can see the error as an amplitude fluctuation in the array (i think thats
the error) it gets more and more dominant with higher frequencies and at some
point you hear a deep note, which seems to be the amplitude modulation coming
into the hearable range.
or am i wrong? i also could
Hi Simon,
Maybe it's just me but I did not find an attachment with your last post.
By the way I found a bug in my upsampling method: apparently,
[samplerate~] in a resampled subpatch needs some time before it
reports the correct samplerate, therefore the subpatch used wrong
values for filter freq
hi katja,
i tried your patch and had a look at it. it’s beautifully programmed :-) so
skilled.
thanks for taking the time and it’s very interesting to see a different style
and different thinking to get to the “same” outcome.
i tried (with a different version of the patch) just to replace osc~
That is certainly true with bass (electric or upright) as well. (I'm
watching this discussion with fascination!)

Hi Simon,
I'd be curious to see this adaptive filtering work in practice. Could

exceed a 3 octave range either. Only thing is, in vocals the strongest
component is sometimes not the first harmonic but the second, when

katja,
exactly! i filter the input based on the output of the pitch detection. i used
this for quite some time with my doublebass (but with a pickup per string) and
it works perfectly. i get no octave jumps or glitches at all. the version i
shared here is planned to be used for vocals, i have t
Hi Simon,
See attachment for an upsampled version. I used a 6th order lo pass
filter with cut off at 1/4 of the original sampling rate. This seems
to work with max. 8 times upsampling. Period length error is then
limited to 1/8 sample.
You mentioned adaptive filtering of a real life input signal.
Katja thanks for your Inputs! Will Look at the Patch tonight. Simple lowpass
Filtering? I tried to upsample with a Block object but the biquad object
stopped outputting Pulses. If you don't mind doing a Version with upsampling
that would be fantastic.
Well i just copied from the Gr300 schematic
Hi Simon,
So your method counts samples per (zero-crossing) cycle, is what I
learned from studying the patch. Very nice how you do this with tilde
objects. It seems possible to get equivalent result with only one
[rpole~], when using the positive pulse as trigger for [samphold~] and
with two sampl
nice changes with expr~ ! but i think you missed the point of the beginning of
the patch. read in my first e-mail for an explanation of what this patch does
exactly. it is an gr300 analog guitar synthesizer clone (well one voice of it).
it is intended for real-life signals so there needs to be a
Well i know exactly what the Patch does... I just dont know why the two numbers
before the Addition Need to be -1 And -2 :-)
Will Look at your Version asap.
Cheers

I have no idea what the patch is doing either, but I was able to clean it a
lot.
many things that didn't need to be there

roman, thanks for your inputs.
i tried both fexpr and expr and sticked to fexpr at some point, don’t know why
though. will change it back! (i remember reading that fexpr was more expensive
but also more precise)
to make the whole thing work with real world signals (bass guitar in my case)
you
That works very well. Good job and thanks for sharing!
One minor thing jumped to my eye: Your patch uses some instances of
[fexpr~] and all of them actually don't need [fexpr~] functionality. I
experienced that [fexpr~] is quite expensive, which seems apparent
considering it is designed for feedba
hey miller and list,
find attached a version that works beautifully. it's a dirty hack without
upsampling but it works extremly well. don't ask me why, i have no idea.
thanks for all the help miller, really appreciate it! and thanks for pd in
general :-)
cheers,
