When you feed the center frequency into a bandpass filter, it passes - as it is supposed to do - the frequency.
But when you cut the input of the bandpass filter it stays on producing that freq a while and than it dies out.
Does anyone know why?

( attached patch makes it clear, if necessary )

Does anyone know how I can control the on-board speaker using pd?
Just like the program "beep" does. (http://www.johnath.com/beep/)

Thanks

Hi there,

Please help me out with this.
I'm have been using pd a lot but I still cant figure out how to do some things that would be easy in other program languages I know.

I want to make:

100 oscillators
all at a different pitch, n+0.1, n+0.2, n+0.3, n+0.4, n+0.5, ...., n+10.

And I don't want to make 100 oscillators and connect them by hand.
It is faster to that than to figure out how I could do it otherwise, but it is just stupid to do it this way.

Thanks in advance,

I've made a patch that makes sound somewhat like a F1-Racetrack.

Does anyone know what I can use better than a square wave for the engine-sound?

For some reason, when I use a sawtooth, there is little sound to be heard. ( do they cancel each other out or something? )

Thanks in advance,

I was experimenting with pd, when I came upon the following:

( In advance I want to say it is much easier to understand making use the .pd attached )

Using [metro] and [tabwrite~] I graph all the audio output.
I'm making a sound with an [osc] and [pow~] and connect it to the [tabwrite~] as well as the [dac~], thus he [tabwrite~] and the [dac~] get the same signal.
The strange thing is: I can hear the sound but the graph displays nothing!
And even peculiar, when i add the signal coming from [pow~] to an [osc~] ,doing nothing but sitting around and being connected ( no frq specified ), I CAN see it in the graph.

Is this a bug?
Or do I just don't know what I'm doing.

Thanks for your help.

Hi,there

I can't make [&&~] , [||~] , [==~] objects in pd.
But I can make them without the ~. I saw on a tutorial that it is possible, because they used it in an example.
I have version 0.40-2 and using ubuntu

Please help me,

I had the same problem a while ago, here is the topic:

http://puredata.hurleur.com/sujet-1964-math-logic-functions

I think this is what you mean.
Thanks to hardoff for the answer.

In short:

[==~]

can be replaced by

[expr~ $v1==$v2]

Ha Guys, thanks for al you posts.
I've read them all, but I am still wondering,
why do I see NO graph
but I CAN hear sound

While they are using the same output as their input. ( the graph and the dac )

( By the way it is not my sound card, and reducing the graph has no use either )

Thanks,

When i disconnect it there's no graphing. But then the [pow~] needs something feeding its right inlet, then it works.

But then, how do you explain there IS sound and no graphing!

@domien said:

Strange, it seems to work over here (audio and graph). Maybe you could resize the graph a bit because tcl/tk (the library used to give pd its visual aspect) sometimes lags behind... But that's really a very wild guess...

Even if you disconnect the osc which is doing nothing?
