Hi all,

suppose we have a .wav file which contains a melody line created with a sine oscillator.
So the timbre is purely sinusoidal, very poor.
What ways are there, in Puredata, to transform that file so that the timbre becomes more interesting and complex?

More difficult question: is it possible to transform that sinusoidal .wav file by requesting the software to take the waveform from an assigned audio sample (sound of organ, choir, violin, etc)?

Thank you,
a.

@atux Writing to a file is already implemented (but in mono as the source is mono) in [pd dsp]..... at the bottom right of the patch window.
David.

Was mono, I made it stereo:

The exported .wav file is ok.
Thank you,
a.

I ask for advice on the patch I'm talking about.

How do I save in a .wav file the sounds that are played?
This is the patch:

This is what I would do, but I don't know where to connect it :

Thank you,
a.

If it has been updated for 64-bit then you will find it through "Deken".

Yes, through Deken I found this version:

unauthorized-v0.0.extended-(Linux-i386-32)(Linux-amd64-64)-externals

Now the patch (in pd 0.52.1) works fine.
Thank you,

Hi all,

in Pd [version 0.52.1 on Linux] I'm trying to run this patch (a Wind Generator):

http://puredata.info/Members/thinkingsoundpd

...but in the console it says:

opened alsa MIDI client 129 in:1 out:1
 grid grid1 100 1 1950 100 1 1750 0 1 1 10 10 125 133

... couldn't create
ALSA input error (snd_pcm_open): No such file or directory
ALSA output error (snd_pcm_open): No such file or directory

Which external do I need?

Are there any other wind generator or also blown sounds generator for pd on Linux?
Thank you,
a.

Hi all,

I would like to know if in Pure Data it is possible to do this:

play MIDI note number 45 for 2 seconds during which there is a continuous (non-discrete) linear glissando until you reach MIDI note 68.

Is there a concept of a continuous glissando between two MIDI notes placed any distance apart?
Is it possible to save this information in a MIDI file?
[Performance is intended for a continuous pitch MIDI instrument, such as an organ, cello, choir, etc.]

P.S.: in pd I can already do the "discrete" glissando (chromatic scale, also microtonal scale), but here I am talking about a continuous glissando and not a succession of closely spaced notes.

Thank you,
a.

@atux If you send the message [dump( into [boids 2d] what value is printed to the Pd console for the "number" parameter?
Sending [number 7( into [boids 2d 15] will make only 7 of them move. The others will be stationary.
So maybe sending in the message [number 115( will get them all moving..?
David.

Hi,

yes, sending the [dump( message into [boids 2d] object and printing the parameter values ​​in the Pd console, I found that the parameter values ​​completely change from those declared in the patch.
The speed changes from 3 to 0.1, so obviously nothing moves.
The maxspeed and inertia also become very small (about 0.2).

However I have added some sliders to control the values ​​directly and more comfortably in realtime, something like this:

...and everything works fine. The behavior is what you wrote in your post.

Thank you,
a.

EDIT
Now I'm trying to figure out how to get the (x,y) coordinates of each boid during motion, in two distinct number boxes for each boid, with a certain time step (as small as possible).
I think I succeeded by doing something like this:

This is the start of the output stream in the pd console:

-> This is my fault, and it's not an important issue... I fixed it in zip.

If you need more boids number like 115, you also need to change [clone myboid 15] to [clone myboid 115]

Sure, I did that too. The boids increase in number, but do not move.

@60hz said:

It works for me, but you certainly need to refresh the [number 15( message AFTER create the [pd boid] subpatches creation.

Also, here is a better version using [clone] object that has been part of puredata and makes the design more convienient.

(Note that boids Gem examples need [poltocar] object fom cyclone to work well)

boids2d_clone_Gem_example.zip

Hi, your patch works fine, the boids move correctly, but when I increase their number for example from 15 to 115, also doing the "refresh after..." as you said, the boids increase but stay still, they don't move.
Now, when I open your patch, I get these errors:
