So what do I need to do to use movies as textures? I will try the new patch provided by Guenter tonight (thanks Guenter!) that will hopefully repair video\'s as textures and ieee1394 video (pix_video) as well. > > 01.Text.pd > > Gem has been compiled without FONT-support ! > > this is a problem with gem\'s debian package too. > i think that ftgl-dev is available vor amd64 too, so it shouldn\'t be a > real problem (but rather a bug in the debian-package which i have > already filed and günther is aware of (i hope)) I think I built ftgl from source so all the prerequsite libraries should be there...

MIDI Control - Level 0.01 - Another Novice Q.
by Ryan Supak 05 Oct '04

05 Oct '04

Hi, I had my first good, solid 3-hour stint with pd yesterday. I've got to say -- it is, to me, a much more creative experience that programming in a traditional environment. Here's my current goal: I'm trying to enhance the functionality of 2 simultaneous M-Audio Oxygen8s by making the pitch-wheel of each a "meta-controller" - in other words, I want to use the pitch wheel of each to control how the unit controls things. When I "bump the top" of the pitch-wheel range, I want the MIDI Channel for that Oxygen8 to increase by one, and when I "bump the bottom" of the pitch-wheel range, I want the MIDI Channel for that Oxygen8 to decrease by one. Also, the units must act completely independently of one another. Here's what I've done so far to attain the goal: Created a subpatch that uses [ctlin], [notein], and [bendin] to take in all the MIDI events I'm interested in, from all physical controllers. Packed all this data, 7 integers worth, into "midiBall" and sent it out. So far so good. The main patch allows selection of the MIDI channels that the initial data for each physical controller comes from. (By default each physical controller transmits on channel 1, so that makes the Ctrl1 listen channel "1" and the Ctrl2 listen channel "17"). Still coming along great... Here's where I run into trouble: Created a subpatch to handle the incrementing and decrementing of send MIDI channel, per controller, via the pitch wheels. The pitchwheel has a control threshold: If the value is under 2000 then send a "minus1" to the send channel amount for that controller. If the value is over 14000 then send a "plus1". The problem is, though, that I only want to send a single "plus1" for the entire duration of time that the pitch bend value exceeds 14000. The pitch bend should not be eligible to send another "plus1" until the value goes back below the threshold of 14000 and returns above it again. In effect, what's happening now is that the pitch bend "bumps the top", but it increments the channel value 5, 10, 100 times (since the threshold is past everytime the wheel value registers) when I only want it to increment the value once. As far as I can tell, here's the problem boiled down: I need to construct a logical mechanism that has a threshold. If the threshold is passed, a *single* message is sent, and another "passed threshold" message is not sent until the threshold is "unpassed" and then crossed once again. Thanks in advance for any insight, and thanks for reading!! rs

dynamically loading abstractions
by shreeswifty 05 Oct '04

05 Oct '04

In GEM, I created a patch and I want to call it in as an abstraction dynamically. To be spceific I made a patch that grows a tree, if the tree drops a seed, I want to grow a new tree where the seed dropped. How could call in that abstraction that creates the tree dynamically, so I dont have to have a bunch of patches just waiting to be triggered.

Graz conevention, filtered bangs, and studying at IEM
by beau25＠access4less.net 05 Oct '04

Hello Sven or other convention attendie could you please tell me more about these two pictures, Who is it, system, patch? Anything would be helpful, thanks: http://www.guckes.net/pics/2004/09-29/.tmp/dscn8050.jpg.html http://www.guckes.net/pics/2004/10-02/.tmp/dscn8567.jpg.html Hi josh stiener, I usually filter bangs using pack & unpack boxes where the bang triggers data values stored in the other lines of the pack. Hello Kyle Klipowicz, Why don't you go accross the river and talk to people @ UMKC. I went there for an electro-acoustic festival in 2000 and it was pretty good. Do they still have that festival? If you use pd maybe you could get envovled. Also if they don't take you at IEM, then try UCSD, Miller teachers some classes there which you may be interested in and they would be taught in English.

OT: Studying at IEM
by Kyle Klipowicz 05 Oct '04

05 Oct '04

Hi all~ I've been trying unsuccessfully to contact members at the IEM regarding a possible internship/semester abroad in Graz. Hopefully the reason my requests for information have been ignored by the IEM staff I've emailed is due to the frantic schedule of the recent convention. My personal story is that I'd like to study outside of the U.S. for a semester and am doing an undergraduate mathematics research project which involves studying Dr. Puckette's book and developing various synthesis and visual systems with Pure Data. However, Kansas State University is not the best place to find learned instructors in this esoteric field. My wish is to go to Austria for the spring semester of school and study with some of the masters. I need information please before October 13 so I can discuss arrangements with the Study Abroad program at school and also with my mathematics advisor. Specifically, I need to know tuition cost, living arrangements, and the varieties of programs offered through the IEM. After seeing the pictures from the convention, I know that Graz is the one place in Europe where I'd feel like my time was well spent. You have no idea how much I long to sit in a room full of people who have even the slightest awareness of what Pure Data is, and why it is the most important piece of free software in current audio/visual development! Thank you. ~Kyle Klipowicz ,.;:`'*'`:;.,.;:`'*'`:;.,.;:`'*'`:;.,.;:`'*'`:;. Read my thoughts. http://perhapsidid.blogspot.com "The bigger things get the smaller and duller or flatter the globe gets.

Gem initial trial run errors.
by thewade 05 Oct '04

05 Oct '04

I used Guenter Geiger\'s patch to get gem working on my x86_64 laptop so im not really sure of what gem is configured with. I was just going through the gem examples to see whats configured and I got the following errors: 24.time-filtering.pd pix_film:: quicktime4linux support pix_film:: libmpeg3 support GEM: pix_film: Loaded file: /usr/local/lib/pd/doc/gem/examples/04.pix/../data/alea.mpg with 31 frames (320x240) GEM: Start rendering pix_texture: not using client storage mpeg3video_seek: frame accurate seeking without a table of contents is no longer supported. Use mpeg3toc <mpeg file> <table of contents> to generate a table of contents and load the table of contents instead. 00.SimpleVideo.pd GEM: pix_video: do video for this OS 01.Text.pd Gem has been compiled without FONT-support ! 03.ChangeText.pd Gives me a seg fault! 01.primQuad.pd doesnt seem to do anything 02.fountain.pd part_velsphere: this is obsolete, use [part_velocity sphere <x> <y> <z> <r>] instead 03.View_OSD.pd gives me a seg fault I just post these either to report changes, or to get help reconfiguring my build of Gem. Thanks for the help! -thewade

Hi there: Thanks for your reply! >Sorry, I tried to look at your drums, but got carried away by your >Error patch, which I think is really fabulous. I'm having a lot of fun >with it and it's the ideal thing to blow away the post convention >blues. Cool, glad to know you had fun with error too. Well, Error is more fun while the drum sounds really are just tools that I made. > >Anyways, befor I'm back to your patch, two quick tips: > >* use sends and receives, dude. Patchchord patchwork is not good and > will make it hard not only for others, but for yourself to > understand your patches (later). Ya, I agree, I used to use sends and receives to make my patches look really clean. But for some reason now I find myself like to connect things up and follow where the line goes:) > >* get RRADical: http://footils.org/cms/show/1 I wish I have read this before I made the drum sound collection now. Its the kind of thing that has been in my mind for a while. Building intermediate reusable modules for patchworks. I think I will come back to you on this with more questions after I have read it better. Cheers CHUN

Drum sound patches....
by chun lee 05 Oct '04

05 Oct '04

Hi there: I hope its ok to call for feedbacks on patches here. Otherwise, is there a dedicated place to do so? I have just made some drum sound patches and I wonder if anyone would take a look and perhaps some feedback would be nice. You can load each individual modules like loading a external and there are a few simple synthesis parameters to control the behavior of the drum sound. They can be downloaded at: http://www.sonicvariable.com/software.html Cheers CHUN

redirection or piping shell object
by jim ruxton 05 Oct '04

05 Oct '04

Hi is their a way to redirect or pipe the results of commands going to the shell object. For example is there a way to execute: cat foo.txt > /dev/ttyS1 or ls | grep pd >From what I've seen the shell object ignores the redirection > and pipe | signals . Thanks
