Binary for latest GEM for MacOS 10.4 PowerPC?
by Matteo Sisti Sette 22 Feb '10

22 Feb '10

Hi, I installed the latest version of Gem (0.92.2?) on a Mac PowerBook G4 with MacOS 10.4 and it doesn't load: it gives this error message: """ /Applications/Pd-0.42-5.app/Contents/Resources/Scripts/../extra/Gem/Gem.d_fat: dlopen(/Applications/Pd-0.42-5.app/Contents/Resources/Scripts/../extra/Gem/Gem.d_fat, 10): Symbol not found: _close$UNIX2003 Referenced from: /Applications/Pd-0.42-5.app/Contents/Resources/Scripts/../extra/Gem/Gem.d_fat Expected in: /usr/lib/libSystem.B.dylib Gem: can't load library """ So I googled the archives and found an old post describing the same issue and it said it must be compiled on 10.4 to run on 10.4, and there was a link to a compiled binary. However, that was an older version (0.91.something) and it loads and works, but [pix_video] doesn't work: it says: ""error: [pix_videoNEW]: do video for this OS"" (where I guess "do video" is a typo for "no video", unless it is a remainder for the developers) So I need the 0.92 version, or a version with working [pix_video], compatible with MacOS 10.4 Does anybody have such a precompiled binary, i.e. version 0.92.2 for MacOS 10.4? Thanks m. -- Matteo Sisti Sette matteosistisette(a)gmail.com http://www.matteosistisette.com

Hi, i'm running Gem 0.92.2 compiled by myself and Ubuntu 9.04 64 bit I've a problem with GEM: when I launch PD it throw me this error (found nothing on google): /usr/local/lib/pd/extra/Gem.pd_linux: /usr/lib/libMagickWand.so.1: undefined symbol: ClutImageChannel Gem: can't load library Never had this problem before on the same machine... maybe a libmagick upgrade? thanks

playlist ( where the hell are you ??? )
by Gintaras Lau. 22 Feb '10

jack on through console?
by João Pais 22 Feb '10

22 Feb '10

Hi, do you know if there's a way to turn qjackctl on through the console? That is, the program is already open, but instead of clicking start or stopp, I wanted to do it with bash commands.

Hi Josh, welcome on board! I also went from Reaktor (and Audio Mulch) to Pd, but that was many years ago in the dark ages when I used woolly mammoths on a treadmill to power my laptop, and cavebear bones as a physical interface. If you're into granular stuff, have a look at my Particlechamber abstraction: http://macumbista.net/?page_id=514 Due for an update after 7 long years sometime this spring or summer ;-) Best, Derek Josh Moore wrote: > It's great fun, more stable than Reaktor which I think is yuck to > begin with, and I'm mostly learning for the lack of good live granular > synthesis on the mac. -- ::: derek holzer ::: http://macumbista.net ::: ---Oblique Strategy # 16: "Assemble some of the elements in a group and treat the group"

poly second inlet
by Matteo Sisti Sette 22 Feb '10

22 Feb '10

Hi, What does the second inlet of [poly] do? It doesn't seem to change either the number of voices nor to dynamically enable/disable voice stealing. The help patch doesn't say anything about it; there is a comment that says: "<-- scroll to change the value of delay in milliseconds." where the "<--" arrow points to nothing. I thought the autor of the help patch may have forgotten to put a number box connected to the right inlet (which would be just next to the comment); however I have tried to connect a numberbox and I don't see any delay, neither on note-on's nor on note-off's (the latter was what I expected, since it would be very useful to account for release time when managing polyphony) Is that comment an error (probably copy-pasted by accident from another object's help patch)? Or does the second inlet actually control some delay that I'm not seing because I don't know where to look? thanks m. -- Matteo Sisti Sette matteosistisette(a)gmail.com http://www.matteosistisette.com

displaying waveforms in gem
by Andrew Faraday 21 Feb '10

21 Feb '10

Hey All I'm looking into some live sampling work with direct visualization in Gem. I'm just wondering if there's a way to use the waveform of a sample (I.E. What you see in an array containing audio) as an object in gem. The only way I can think of doing it is taking a screen shot of an array, saving that to a file and using that as a texture. This way isn't particularly adaptable, however, as I'd need to go through the process for any new sample. Any Ideas?

PD, xxxduino and adafruitmotor shield
by JNM 21 Feb '10

21 Feb '10

Salut We are in Dakar, SÃ©nÃ©gal, for the second PD/XXXduino workshop in west Africa where we prototype a suitcase for the pedagogy of interactive art.(( http://www.craslab.org/valise (draft, english soon))) We try to find a solution to control the stepper motor and dc motor with PD standard firmata 2.1 with the adafruitmotorshield. Servomotors are easy to pilot from PD, but steppers and DC motor are piloted by a chip. The docs says (http://www.ladyada.net/make/mshield/faq.html): "The DC/Stepper motors are NOT connected to the Arduino directly. They are connected to the 74HC595 latch which is spoken to by the Arduino. You CANNOT talk directly to the motors, you MUST use the motor shield library" Does anyone in the list has found a hack to talk to this chip from PD to pilot the steppers and DC motors ? Thanks JNM, JÃ©rÃ´me Abel, and 17 Senegalese and Malian students
