Using Pd to play drums in a band
by Carlo Trimarchi 21 Mar '10

21 Mar '10

Hi, I recently started learning Puredata reading this tutorial: http://www.pd-tutorial.com/english/index.html I'm generally interested in making electronic music, but since I'm trying to play in a band as a "drummer" I wanted to use Pd as a drum machine. I'm thinking about a live situation and the best approach to that. My idea for this, at the moment, is to create a patch with some sort of step sequencer and a matrix or something to change drum patterns. Then, for a live concert I'll have this patch saved different times (once for every song we should play) with different patterns. Then I'd like to implement something to play with the drum sequence: adding effects, moving samples, randomize the pattern. Everything to actually play something live. One of the main problems I'm thinking about is the metronome. I don't think we are going to use a metronome or a click live to play at a predetermined bpm and often the drums start after others are playing at a certain bpm. So it would be hard to define a fixed bpm and stick with it live. I was thinking if is there a way to make a patch retrieve the bpm dinamically. For example, when a song starts, I can tap my fingers on a key and from that it can retrieve the bpm that I can use in the rest of the song. Can you suggest me a way to do this? Then, since I'm a beginner and I just know the basics of Pd programming, what can I study in particular to create a drum machine? And, do you have other suggestions or better approaches to achieve my goal? Thanks for your help, Carlo

Just a bit of fun

Hey All I've attached a patch that chases up an idea of mine. Having recently started on non-graphic programming I thought I'd take advantage of PD and it's methods for a bit. Let me know what you think Andrew _________________________________________________________________ Got a cool Hotmail story? Tell us now http://clk.atdmt.com/UKM/go/195013117/direct/01/

mic preamp: hardware or inside Pd?
by Roberto Duarte 21 Mar '10

21 Mar '10

Hello all, maybe somebody could bring me some lights about this: I want to jam with some piezos and coil mics, I could get a cheap M-Audio Quattro or similar (no pre amp included) and all this into Pd for some processing. What would be better: 1. to get or build some hardware preamps or 2. to amplify the signal inside Pd? Another way to go could be, instead of buying a dedicated Audio Interface, build one on an Arduino board or on this new CUI32 USB board, using those (several) analog inputs. For me, in a way could be good also, because of learning how to do it. I will appreciate any help or tip on this..

I'm almost finished revising the docs: 2.control.examples, 3.audio.examples, 4.data.structures, and 5.reference.

I think it's >worth, and I wouldn't like it to be easier. I disagree-- I would like it to be easier, and it should be easier. More time spent trying to figure out how dollarsym atoms get expanded is less time spent making music. The last paragraph of Pd Manual 2.6.5 doesn't reflect the current state of Pd, btw. Do items like that belong on the bug tracker? >Studying and Teaching I found Pd can operate kind of "natural selection" >that sometimes is needed in some context. By that logic there should be even less documentation (or more outdated/ erroneous docs). But what are the characteristics that make students fit enough to avoid death and reproduce themselves into the next generation of the Pd learning environment? As far as I can tell, Pd crashes will remain Pd crashes, regardless of whether the output isn't boring, so I don't think I understand what you mean. On a related note, a [sculch-gate~] object would be cool. (sculch = junk) -Jonathan

vinil bass gambiarra
by Ricardo Brazileiro 21 Mar '10

21 Mar '10

re all this is my recent project with a vinyl records and turntable gambiarra which capture the frequencies of the LP and transform them in granullar synth and bass wavetable. I used pd (fiddle~, bonk~) to capture signal through piezo adapted in the needle. http://rbrazileiro.info/blog/metrobang-vinil-bass-sequencer-vintage/ http://www.youtube.com/watch?v=t4JTJx2vAhI abraços! -- ricardo brazileiro http://rbrazileiro.info

video of Pd Workshop for 11 year olds
by Hans-Christoph Steiner 21 Mar '10

21 Mar '10

Here's a video of a Pd workshop I taught with 11 year old kids in New York. It was amazing how they picked it up and had so little fear to experiment: http://eyebeam.org/press/media/videos/an-introduction-to-electronic-soundsc… .hc ---------------------------------------------------------------------------- Looking at things from a more basic level, you can come up with a more direct solution... It may sound small in theory, but it in practice, it can change entire economies. - Amy Smith

Hi , any idea where can i find the source code of PDa? i want to try to compile it directly on maemo 5 because i had no luck runing the compiled version neither with pd vanilla, any idea? Arturo Thanks

Re: [PD] nogui, no signal
by Matteo Sisti Sette 20 Mar '10

20 Mar '10

Hi, I did some very huge and complex patches in the past with lots of [switch~]es (no [block~] though) and I used -nogui regularly, and never came across any problem. I guess this is not enough to completely discard [switch~] as the source of the problem but it does give a clue that the problem is probably somewhere else... I had no gop-enabled abstraction or subpatch however in those patches I used with -nogui.... Btw I don't understand the [netreceive] workaround...

pix_snap + pix_record = problem
by Matteo Sisti Sette 20 Mar '10

20 Mar '10

Hi, I'm trying to use a [pix_record] after a [pix_snap] but I get errors and it doesn't record. The help patch does work, and I could make my own working test patch with [pix_video] followed by [pix_record] and it does work. However, when I try with pix_snap (to capture what I'm rendering and record it), I get the following error as soon as the gemhead is connected to the chain: error: recordQT: EndMediaEdits failed with error -2008 Then, when I send it "record 1, auto 1", I get these errors: error: recordQT: CreateMovieFile failed with error -47 error: recordQT: EndMediaEdits failed with error -2008 If I delete the pix_record and replace it by [pix_texture] | [cube 4] I see the snapped image (snapped every frame), so [pix_snap] is working correctly. Any idea? What are error -47 and error -2008? (btw do errors really have negative codes or is it some type error?) Thanks in advance m. -- Matteo Sisti Sette matteosistisette(a)gmail.com http://www.matteosistisette.com
