5Day Pure Data Workshop --- London, June!
by Ryan Jordan 07 Jun '10

07 Jun '10

>>>Please forward to anyone you think may be interested... A10Lab presents a 5 Day Pure Data Workshop lead by Luca Carrubba and Oscar Martin. CRAZY GENERATIVE A/V MACHINES!!!! The aim of this workshop is to learn simple programming strategies for the creation of audio/video software tools for live performances. Generative or interactive pieces of software that let artists create and control video streams and audio processing in real time. During the workshop we will use puredata, a free (as a bird and as a beer) graphical programming language particularly focused on the processing of audio and video data in real time. Puredata is a tool for artists who want to experiment with a different creation pattern, with a freedom to build from scratch their own instruments. You don’t need to be a programmer to begin to build your tool. In 5 the days long workshop you will learn the basics of the language, how to manipulate or create a video and how to play with audio. At the end of the workshop all the participants will take part in a performance event open to the public. >From Monday 21st June to Friday 25th June 2010. 3 hours a day. 7pm - 10pm. Saturday 26th June --- Live performance event with invited performers and all participants from the workshop!!! Book now! Participation is £100 and limited to 20 people. Book online here > http://www.eventbrite.com/event/695932553/ For more information contact: info(a)a10lab.com http://a10lab.info/ Workshop leaders: Luca Carrubba Graduated summa cum laude in Sociology of Communication, Luca Carrubba has worked for 5 years under the new media field as artist and independent researcher. Formed between institutional and underground medialabs in Barcelona and Madrid, he focus its production on the interaction between audio and video, always share the practices and codes. Based its action on certain keywords like DIY (do it yourself), knowledge sharing, accessibility, recycling and social movements. Also participated in many workshops to spread free software/technology/culture among Italy, Spain, England, Germany, France, Argentina, Brazil, Palestine and China. He is now professor of new technologies for art in Libera Accademia delle Belle Arti, Brescia, Italy.

That is where he came into contact with sound art through Leopoldo Amigo y Bartolomé Ferrando. A sound explorer, he bases his work on the deconstruction of field recordings and the creative use of technology errors. Luthier-digital with a “pure data” environment, which he uses to develop his own experimental tools for processing and real time algorithmic-generative composition. He can be placed somewhere between Computer Music, the Aesthetics of Error, and generative Noise. He seeks the creation of virtual sound universes, imaginary soundscapes that encourage active listening and a different sensibility toward the perception of sound phenomena. He works under the open source paradigm.

many DVI ports with Debian/Ubuntu and Gem
by Hans-Christoph Steiner 07 Jun '10

07 Jun '10

I am looking into doing a 10 screen installation using Pd/Gem. I'd like to run it on as few computers as possible. Anyone have any recommendations for Debian or Ubuntu setups that can have like many DVI ports in one computer? .hc ---------------------------------------------------------------------------- I spent 33 years and four months in active military service and during that period I spent most of my time as a high class muscle man for Big Business, for Wall Street and the bankers. - General Smedley Butler

MIDI In-to-Out Latency

> Just to see if I got that right, the rip is: > > keyboard -> YOKE in -> YOKE OUT -> PD IN -> PD OUT -> YOKE IN -> YOKE OUT > -> CUBASE IN > No. The pathway is: keyboard ->M-Audio Firewire 410 MIDI in (via the FW 410's driver) -> PD in -> Pd out -> Yoke in -> Yoke out -> Cubase in. The Yoke is only in the path once. >> The sluggish response is clearly due to Pd. Also, it's consistent whether >> > Pd's patch window is in or>out of edit mode. > How can you be sure?

[textedit] object for pd?
by Kim Cascone 07 Jun '10

07 Jun '10

I'm building a patch that takes a text file and selects random lines to display I've been looking for an object similar to [textedit] Max/MSP so I can display the text with formatting (i.e. type size, font, color etc) does anyone happen to know if there is a similar object as [textedit] for pd? or something that would work in its place? thanks in advance!

plugin~ external
by Kim Cascone 07 Jun '10

07 Jun '10

I know this topic has been brought up in the past and I searched the archives hoping to find some more info but... I'm unable to get plugin~ working on Pd version 0.41-4extended I have set a path to my LADSPA library as well as the plugin~ dir in my extras directory I can instantiate an object but I get the following error when loading the tap_autopanner and tap_eq plugins with the plugin~ object: plugin~: constructed plugin "TAP AutoPanner" successfully plugin~: plugin ports: audio 2/2 ctrl 3/0 plugin~: plugin active plugin~: close_plugin (x) plugin~: destructed plugin successfully config listed below I chose to test with the TAP plugs because a) they've been around a long time and still being worked on IIRC b) they work in Ardour and AMS for me and c) they are from the same collection of LADSPA plugs made by the same developer so my questions are: - why do some LADSPA plugs work while others do not? - I remember Derek mentioning a 'workaround' in the archives but was unable to find the solution - (was it recompiling the plugin~ object?) can someone point me to the workaround? - does anyone else use this external and have it working on Linux? - is there a newer, more robust or another external for hosting LADSPA, LV2 and/or VST plugins? any help is appreciated! ciao!

Recreating sampled sound with variations
by Joey Ma 07 Jun '10

07 Jun '10

I would like to use a number box, or a similar control, to control the number of playback. For example, I would like to increase the number of times that a sample is being played, with separate control over the sampled sound, such as to produce a crowd of applause with a single sampled clapping sound. I've thought about objects such as route~, sel~, send & receive, qlist, using sub-patches or abstractions, but I still can't quite figure out the signal flow and a nice way to create a patch that reaches my objective. I understand that I want some control over the pitch, "playback speed" or chunk size, but I'm quite lost as to how I can lay down the foundation (elements) of the patch and a way to control this type of multi-voice situation. I also have a feeling someone must have done it already... but I can't seem to find it! Any help is much appreciated.

Looking for a pedal controller
by Achim Bloch 06 Jun '10

06 Jun '10

Hi listees I'm looking for a pedal controller that is accurate enough to send OSC messages to pd, in order to control some effect patches for my guitar. Can anyone help me in finding a good one, maybe providing a perqsonal experience feedback? Thanks in advance, Achim
