Hi all,

I have a txt file containing x,y values from multiple overlaid graphs.
For example, this txt file contains (x,y) coordinates for 4 independent graphs that start and end at different points::

Below I imported the data into a spreadsheet, separated it into different columns and plotted the graphs:

In PureData, is there a way to read a txt file of this type file and plot the four graphs on the same canvas?
test_graph.txt

Thanks,
a.

@atux Y-range goes from Ymax to Ymin.

So in the array properties it must be set:
x from min to max;
y from max to min.

In fact, setting x from 0 to 11, y from 61 to 60, it's drawn correctly.
OK, thank you,
a.

Hi,

if the list of values is increasing from 60 to 61, why does the graph appear decreasing?
In the array1 properties I set x from 0 to 11, y from 60 to 61.

Thank you,

I was wondering how to create a patch to simulate the sound of a stone thrown into water (realistically).
Are there any patches already made?
Thanks,
a.

When using soundfonts with instruments that have a significant transient such as piano, organ, strings, etc., is there a way to remove all transients (except the first note) so that, by scrolling "pitch" box number up and down, you hear a single continuous glissando?

Thanks,

[netsend] help for the [send( message says "same as list" so you can also do

[hslider]

[list prepend z]

[netsend]

Yes, that's how it works too.
pd2py_v3.pd
For less computational effort, is one preferable to the other, or are they equivalent?
Thank you,
a.

@atux You can try that....... pd2py_v2.pd
Does it work?
If not then post your Python code and someone will tell you why not.

Thanks, it works fine.
But in order for python to receive the values ​​correctly, I had to remove "-b" from [netsend -u -b].
These are some values ​​received from pd:

$ python3 py_from_pd.py
Socket bind completed on 127.0.0.1:9999. Waiting for messages...
Raw data received from ('127.0.0.1', 51903): b'z 0.5;\n'
Decoded message: z 0.5;
Value of z: 0.5
Raw data received from ('127.0.0.1', 51903): b'z 0.509868;\n'
Decoded message: z 0.509868;
Value of z: 0.509868
Raw data received from ('127.0.0.1', 51903): b'z 0.519737;\n'
Decoded message: z 0.519737;

It seems good to me.
I attach both files, so it can be useful:
py_from_pd.py
pd2py_v2.pd

Thank you,
a.

Simply connect the slider to the sender.

Ok, but I left the blank space between slider and netsend because I don't know how to write the variable z that python expects. Something like "send z $1".

Hi,

a Python program needs to receive "z" from pd.

In pd I generate "z" values by moving a slider.
The Python code is already ready to receive z.

What is the correct patch to do this?
Thanks,
a.

pd2py.pd

I found the open-source code VocalTractLab.
It would be interesting to create some c++ libraries for pd.

One could add consonants and make words sound. I don't know if anyone has ever developed this in pd. I think it's extremely complex. It would be very interesting, because the words could be intoned (sung). So get a sung text.

This is a first elementary attempt at using [bonk~].
By setting the threshold, I can isolate the kick and hihat.

test_bonk.pd

Hi,
in a patch I open a drum rhythm (kick, snare, hats) audio file (.wav).
Is there a way to capture the pulses with bangs or numbers, even just the kick, or even better also the snare and hats separately? So capture the audio level peaks, but separately for the different instruments.

-> pd on Linux

Thanks,
a.

this guy has a bunch of good videos on youtube.!

Thank you.
I copied the part I'm interested in, but when I play an audio file with a player, nothing happens.

test01.pd

Hi,
what is the way to capture in pd the audio playing (with any player) on the computer and connect it to a level bar? (pd on linux+pipewire)
Thanks,
a.

@avenir
@jameslo
Nice patch.
Just one question: what is the easiest way to make the previous .wav file not stop when the next file starts? That way you would have some overlapping sounds (at most in a certain time interval all the files could play at the same time).
Thanks,
a.

[...] list-sieve

Perfect.
Thank you,
a.

I was wondering how to use [spigot] as a sieve:
if the input number is equal to any element of list A, pass it through. Otherwise send it out another outlet.
a.

list_spigot.pd

@whale-av
Nice. Basically [spigot] acts as a "switch" that lets the number through only when the condition imposed in the right inlet is met (in this case [== 0]).
Thanks,
