can't open midi port in -nogui

hi list, (using Pd-0.40.3-extended-rc1-macosx104-powerpc.dmg) on 10.4, PPC i use a shell script to startup pd for an installation. it looks something like this: ---------------shell script--------- /Applications/Pd-extended.app/Contents/Resources/bin/pd -path / Applications/Pd-extended.app/Contents/Resources/extra/hardware -path / Applications/Pd-extended.app/Contents/Resources/extra/flatspace - path /Applications/Pd-extended.app/Contents/Resources/extra/iemlib - path /Applications/Pd-extended.app/Contents/Resources/extra/mapping - path /clarafrancesco -lib mapping -lib iemlib -lib hardware -lib flatspace -r 48000 -listdev -nomidiin -midioutdev 1 -noadc - outchannels 2 -nogui -noprefs /clarafrancesco/CLARAFRANCESCO.pd --------------end------------------- but later in the terminal it seems i can't open the midi port. ----------Terminal output---------- 008-06-12 01:10:21.623 pd[4717] CFLog (21): Error loading /Library/ QuickTime/Motion.component/Contents/MacOS/Motion: error code 4, error number 0 (Library not loaded: /Library/Frameworks/ Motion.framework/Versions/A/Motion Referenced from: /Library/QuickTime/Motion.component/Contents/ MacOS/Motion Reason: image not found) 2008-06-12 01:10:21.737 pd[4717] CFLog (21): Error loading /Library/ QuickTime/Motion.component/Contents/MacOS/Motion: error code 4, error number 0 (Library not loaded: /Library/Frameworks/ Motion.framework/Versions/A/Motion Referenced from: /Library/QuickTime/Motion.component/Contents/ MacOS/Motion Reason: image not found) audio input devices: 1.

MasterOfPrayer
by Chris McCormick 12 Jun '08

12 Jun '08

Hi, For the last few months I have been helping my friends Rodney Glick (Artist) and Moshe Y Bernstein (Rabbi) with the technical aspects of one of Rodney's artworks. The artwork, entitled "Master Of Prayer" will be showing among many other fascinating works in Rodney's exhibition. It opens tommorrow night (Thursday), 6pm at the [Lawrence Wilson Art Gallery](http://lwgallery.uwa.edu.au/) at the University of Western Australia. I'm really excited about this project. I got to use Pure Data, voice synthesis (mbrola), and a network based pseudo-AI (Pd) to help Rodney and Moshe create a really compelling and thought provoking artwork. Here's the blurb that Moshe wrote about it: "In the Jewish tradition the full prayer service can be performed only in a quorum of ten adult males known in Hebrew as a minyan. The main part of the service, which occurs three times daily, is the Shmona Esrei, or Eighteen Benedictions. These blessings are first recited silently by the entire congregation. Afterwards, during the morning and afternoon liturgies, they are repeated aloud by the cantor, often referred to as the Ba'al Tefillah or 'Master of Prayer'. In orthodox Judaism any male, whether layman or cleric, over the age of thirteen can lead the prayers. During the repetition of the Shmona Esrei, also called the Amidah, or 'standing prayer', the congregation answers responsively to each of the benedictions recited. In this installation each computer has been individually programmed to respond to the blessings recited by the main computer, the 'Master of Prayer', leading the afternoon Mincha service. Though the installation appears to parody the human condition of prayer by rote, on a deeper level it asks a haunting question about the inherent nature of artificial intelligence. The Jewish sages require kavannah, or 'proper intent' for prayer to be truly acceptable. To the extent that computers can be programmed to 'think', might they not be programmed to this 'proper intent' as well? In a tentative answer to that question, 'Master of Prayer' can be experienced as a high-tech, Jewish version of the Tibetan prayer-wheel or Christian rosary beads." Good night, Chris. ------------------- http://mccormick.cx

Re: [PD] Size of a table
by raul diaz 11 Jun '08

Hi list! Thanks for your answers! I think arraysize is the best way to obtain table size in my case. I know as IOhannes said that I can use the length output from soundfiler, but I load a lot of samples at the same time in the same soundfiler, so it's difficult to get each size separately. I have an abstraction which plays synchronized with a master tempo a drums loop, and it has as argument its table name. So I think the best way is to get the table size with [arraysize $1] or as Hans suggested [expr size("$s2")] for pd-vanilla.

Size of a table
by raul diaz 11 Jun '08

11 Jun '08

Hi list! I have a dumb question. What's the best way to get the size of a table? Sometimes I load a lot of samples on tables with soundfiler and I would like to take the size of each sample as a variable in order to use it with phasor + tabread4~. Is there any object which gets the size of a table? Thanks in advance! -- Raul Diaz Poblete ************************* http://creaciodigital.upf.edu/~i50874/ raul.lete(a)gmail.com Barcelona [Spain]

Hi, I am trying to stretch the information in an audio block. i.e., Original: a, b, c, d, e, ... , N (where N is the block size - 1) Modified: a, 0 , b, 0, c, ... , N/2 (later half of the original block can be trashed) The target of the manipulation is the output of [rfft~] Are there any efficient ways of such manipulations at audio rate? BTW, I've lately been enjoying playing with the output of [rfft~] and would also appreciate pointers to resources discussing pitch manipulation using [rfft~] and [z~] or similar concepts not limited to Pd. Not quite sure what term referrers to this method. Thanks. -- David Shimamoto
