Hi,

I wanted to make a simple looper, and surprisingly enough i didn't find many resources on the web. There are a few topics on the forum, but the only working stuff i've found was either with a delay line (but you can't empty it) or Katja's patch (http://puredata.hurleur.com/sujet-5021-sound-sound-looper-clear-option), which didn't work very well on my computer for some reason.

I recently found out that a simple looper could be done very easily with a single table, provided that it's length was a multiple of the block size.
I 've written a post on my blog about it, and I thought i'd share it here because i suppose it could be useful for other people.

Here it is : http://guitarextended.wordpress.com/2013/08/05/making-a-looper-with-pure-data/

Cheers.

Hi,

The Raspberry Pi is a very inexpensive, tiny computer running Raspbian (a Debian-based distro), and other Linux ditributions.
Many people in the Pd community have been experimenting with this platform in the past months, and I am happy to announce that it is now ready for real-time I/O audio (in case you didn't know...) !

I (and other Pd users) managed to go down to 10 ms latency without audio dropouts with an external USB soundcard.
I made a few guitar effects which run fine on it (with 16 ms latency though, because i use a phase-vocoder for one of them!). You can watch the video here :

Stay tuned on my blog for more instructions if you are interested.

Cheers!

Hello everyone,

I'm writing a blog called GuitarExtended to share my experience in using Pd as a real-time multi-effects for the electric guitar. I have built a foot controller based on an Arduino board, and everything is documented on my blog.

The "targetted" public are Pd users interested in extending the sound of their instrument (I am a guitarist, but it could be easily applied to many other instruments), as well as musicians with little or no knowledge of Pd.

Please feel free to leave a comment, or submit a patch that would be interesting as a guitar effect.

The blog is here : http://guitarextended.wordpress.com

Cheers!

Hi all,
i ve been stuck with a very frustrating problem since a few days. A friend of mine gave me a pretty nice laptop that she's not using anymore, and i m trying to configure it for real time use of Pd. So i have ubuntu 8.04 installed, with the rt kernel and stuff, and it's all working pretty well, except for one thing : hid. And i badly need hid in my patches.
The thing is that Pd basically won't recognize any input device (not even the touchpad) unless i run it as root (sudo pd).

Now, i m pretty sure that something needs to be edited in a .conf file somewhere, but can't remember where. I know there is something about it in Google, since i have fixed the same problem a few months ago (yes i know, i should have taken notes).

I badly need any help!

Hi,
I ve found this page http://ydegoyon.free.fr/software.html (which i suppose most of you must know), and i m interested by the Stksitar~ object. Unfortunately, it requires the STK library to work, and i have no idea as to how i should install it. It seems like i need to compile stuff, but i m not exactly familiar with that. I ve also read in another post by Maelstrom that installing Csound and running it into Pd could give access to the STK library.
So, in short my question is : How can a poor Pd user like me have access to the seemingly wonderful STK?

Hi all!
I just installed Ubuntu studio Karmic (which apparently has the rt kernel back), and everything's working fine ... except for Pd! Which is really too bad because i only installed it to be able to use Pd with the lowest possible latency.
I ve read some thread about other instances of Pd being excessively slow, but i could not find any real solution.
Has anybody encountered this problem before?

Hi all!
I m using Pd to process the sound of my guitar, and i want to plug my pc into my amp in order to use it on stage. As you may know guitar amplifiers are build to accept only a limited frequency range, mine accepting frequencies above 800Hz and below 13KHz.
What i m currently doing is filter the sound just before the dac~ with a [hip~ 800] and a [lop~ 13000]. I have read Puckette's chapter about filters realized that filters are never perfect and some frequencies actually leak out below and above these limits.
So what should i do? Do i need shelving filters instead? I m not sure how to use these though, and in particular i don't know how to set the frequency limit (the settings in the audio example H11.Shelving are in hundreths...? )
Any help would be greatly appreciated!

Hey,

I 've been working on a patch that makes it possible to enjoy the endless possibilities offered by a phasor~ reading an array, but without the inherent limitation in terms of array size.
I will upload it if enough people are interested.

Also, I once came accross this thread (http://groups.google.com/group/rec.audio.pro/msg/c7055c32f0ab1992?hl=en&pli=1), which explains how flanging effect was created back in the sixties. Somebody wrote that one way of recreating it in DSP was to use delay lines, which were unable to create the same sounds due to their limited length. I thought it was challenging, so i built this patch with a phasor~ reading an entire song. Since i can now change the speed of the phasor in real time i can do what engineers would do with two tape decks in the old days.

Anyway, it's not complete yet, but hopefully it should be by tonight.

Hi,
I don't whether this is the right place to report a bug. I appologize in advance is it's not.
I have noticed a problem with the [receive~ ] object. I was working on a channel selector for the audio output of a patch, with three possible choices : stereo, mono right and mono left. I choosed to send [Set name( messages to my [receive~ ] objects : the stereo position sends each channel to each receive~ (which works fine), the mono right position sets both receive~ objects to get the right channel (which also works fine), but it doesn't seem to work with the mono left position. Both receive~ objects are set to get the left channel, but the ouput is clearly not mono (it is quite different from what i hear when i plug my left channel directly into both inputs of my [dac~] object.
I have tried sending the set messages simultaneously, ot through a [t s s] object, or even manually one after the other, but it doesn't seem to make any difference. I suppose there must be a bug somewhere.
Has anybody had such a problem before?

Hi all!
I developped a small thing last year when i was building a patch that would do the work of a mixing console. What i was trying to achieve was to make it as handy as possible so that i could mix my songs live. In particular, i needed a control that could move both the volume and the pan sliders of one track at the same time. Since i have only one mouse, i needed something that could control the pan according to the X-axis of the mouse, and the volume according to the moves along the Y-axis.

I have called it [wheel] (don't ask me why, i can't remember). Just open it, the workings are pretty straightforward. This certainly is no big deal for most Pd users, but i believe it can be useful to some.
