A_GIMME
by Thomas Grill 28 Jan '01

28 Jan '01

Hi list! I'm about to dive into the undocumented depths of writing externals for PD... Only one question for the moment: What is an A_GIMME argument for? thanks, Thomas

comparing pointers
by pix＠test.at 27 Jan '01

27 Jan '01

a patch i am writing (which is getting brain-twistingly complicated) requires that i compare two pointers to see if they are pointing at the same thing. "==" doesnt work, is there any way? the only way i can think of, (and i really dont want to do this) is to traverse each of them and compare their contents - which in this case would be a sufficient test (but way too time consuming). also, what's the difference between a (gpointer) and a (pointer)? i made a version of the "value" object, that works for pointers, and inside it, i pass a pointer through a route statement. it goes in as a (gpointer) and comes out as a (pointer). i can turn it back into a (gpointer) by sending it into the left inlet of a "pointer" object, which seems to be necessary for it to be accepted by the right inlet of a "pointer" object. pix.

[GEM] pix_vid troubles
by joreg＠gmx.at 26 Jan '01

26 Jan '01

u> 3. make a new pd-patch and save it as "nop.pd" thanks. this worked for my first question. u> clicking on the upper-left corner will destroy this window. thanks for this. u> gemwin (possibly with no borders, at least under Win) and even more for that. u> if your screen becomes blue with white letters on it, this looks somehow u> like a your video in. make sure you have a camera connected to your u> capture card. ah..sorry for my bad expression. i was speaking of the microsoft-specific blue screen. u> how did you manage to make pix_rtx work if pix_video crashes all the u> time ? i didn't get pix_rtx to work. pix_video still crashes my pd and sometimes even the system. is anybody else experiencing this problem under win2000? (even taking care of the power of 2 thing doesn't help. pix_draw doesn't work either) creating a pix_video object i get a "connected..." message. as soon as i turn the renderer on, pd dies. i also wonder if it is correct that i get no new "connected at..." message after sending a "dimen .." message to the pix_vid? iohannes what system do you run? (my videosource is one of those hauppauge wintv/pci boards with the latest drivers installed) another error: i'm using the latest 0.32 patch version and when i leave pd i always get the following error: ------------------------------------------------------------------ GEM: pd.exe - Application Error The instruction at "0x02eda4dd" referenced memory at "0x02f11e94". The memory could not be "read". Click on OK to terminate the program [OK] ------------------------------------------------------------------ bug or feature? (0.32 didn't have that) alles, joreg.

q: pd and linux
by mimo 26 Jan '01

26 Jan '01

sorry, but I cant simple take these things as given :) why do you think that mthe window manager makes a great impact on pd? anyway, I'm using (currently) kde 2.1 and xfree 4.2 (yes I know I'm a latest-version-junkee). I do personally think that it's because of the alsa-driver, which seems to be some kind of troublesome. I have another question: I realised that alot of stuff around pd+gem is austrian- and furthermore graz-based. as a matter of (sad) fact I'm also from graz. would anyone around like to show me his working pd/gem-system? regards mimo

pd and linux
by mimo 25 Jan '01

25 Jan '01

after successfully installing pd and gem and playing around with all comand lind settings I#m still getting a lot of clicks whenever I'm moving around the mouse pointer in a pd-window. when outside I get less clicks. is this because my machine is too slow (K6-300; 2.4.0; low-latency-patches; alsa-drivers 0.6-pre2; rme96/8) or have I missed something? regards mimo -- ICQ#27981169 mimo(a)restoel.net mimomalistic music@ http://restoel.net/_mimo/

inverse operators
by Thomas Grill 25 Jan '01

25 Jan '01

Hi list! Maybe this is a stupid question: How do i easily calculate 1/x or -x, of course with a hot inlet for x? I can't figure out which object to use efficiently (except pow(x,-1) or so) without converting into signals. Maybe appropriate objects (inv and neg) should be built into pd. greetings! Thomas

RE: Fiddle Mic Input
by Joel Trunick 25 Jan '01

25 Jan '01

I am now able to read input from adc~ and a sample file... When I send fiddle a "debug" message, it only does it "one-shot". According to the fiddle code there is no place to turn it off. HOW CAN I PERMANENTLY TURN ON "DEBUG" MODE? Or, is there a way to "continuously" send the debug message? Thanks, Joel -----Original Message----- From: Joel Trunick Sent: Thursday, January 18, 2001 12:08 PM To: 'pd-list(a)iem.kug.ac.at' Subject: Fiddle Mic Input This seems like it would be a simple question, but I missed seeing how to do this in the documentation. How do I set up Fiddle to take Microphone and File input within PD? Its seems it just generates a frequency. I would like to use real data. I presume I need to add some sort of box as input to fiddle, but I can't tell how to designate mic (or file) input. Thanks in advance, Joel

netsend killing pd
by //m.ash 25 Jan '01

25 Jan '01

bug? feature? or misconfiguration? the netsend object seems to kill pd (on linux) if an established conncetion to netrecieve is suddenly closed (program termination, system crash,... whatever..). Happened to me using pd 0.31 as well as 0.32 on a linux (redhat 6.2) machine communicating with a winnt machine (receiving with pd 0.31, 0.32 and director) pd on winnt seems to be a bit more stable on this issues, although this action caused at leased some crashes too (i didn't follow them). is this a bug or some miscongfiguration? if it is a bug, maybe it could be regarded in future releases that closing connections from one side doesn't cause crashes on the other side. (a crash on one machine should really not cause a crash on the other machine). if latter thanks for info regards, m.

Fw: serial io on NT
by Ian Stevenson 24 Jan '01

24 Jan '01

Dear pd list, RE: serial object Did I ask a foolish question (I often do) - any hints on the use of the serial object, or, where should I have looked in the first place? On another note - I seem to have quantisation noise or something similar on output from pd to a SoundBlaster AWE64. Output to my Soundscape Mixtreme card is perfect - any clues? I am new to pd and am enjoying it so far - any help greatly appreciated!

midi system real time?
by Aaron Brenner 22 Jan '01

22 Jan '01

Can pd transmit midi system real time messages i.e. start/stop/continue) to another connected device, such as a drum machine? I haven't seen an object in pd that seems appropriate. If I know the midi byte-code number of these messages, is there an object I can use to have them sent? In other words, manually send the staus byte for 'start' - '11111010'? Thanks, Aaron
