Hi! I am building a synth with pd and want to use a triangle wave oscillator with symmetry modulation. I know how to make a triangle wave oscillator: phasor~ cliped~ at 0.5 multiplied by two and substracted by the original phasor signal but i cannot figure how to change its symmetry without using an infinite variable to get a perfect sawtooth waveshape. If someone could help me, i would want an explanation for doing that oscillator. I am not an engineer, so a mathematical equation would not help me a lot. Thanks for any help.

MIDI patching via kaconnect under Linux
by Julius Orion Smith III 27 Nov '03

27 Nov '03

Hi all, I notice that pd is not MIDI-patchable using kaconnect. Does anyone know what it would take to add this support? I have read that the alsa virmidi driver can be used to get the same effect (MIDI from a sequencer program to pd), but I haven't found any documentation yet on how to actually do this. Any pointers appreciated. Thanks, Julius -- Julius (jos(a)ccrma.stanford.edu)

pdp/pidip segmentation fault
by metafor 26 Nov '03

26 Nov '03

hi list what causes pdp/pidip to crash with segmentation fault while using several effects in chain. just effects with mouse feedback like cmap or ctrack are affected and only when i'm using this effects in chain (wiht reg and mix), standalone eg. the help_pdp_cmap is working properly. it seems that it crashs more likely when i'm fastclick several times in the xv. is there a certain "don't do this" with these effects? i'm using pdp 0.12.2, the latest pidp 0.12.11 with pd-037.0 on debian. the system as such is runnig stable. marc

Re: [PD] Models for Gem

yes you ae lucky if you use wings3d for windows it's very easy. getting it to work on linux was difficult. i recommend OSG for testing the models too. cheers~ Pat On Wed Nov 26 11:38:38 EST 2003, Johannes Taelman <j0(a)advalvas.be> wrote: > Ken Locarnini wrote: > >> Can anyone help me understand the models that can be used in >> Gem?

Can anyone help me understand the models that can be used in Gem? Are there any open source freeware programs that can work with them? Thanks, Ken

getting started on OS X 10.2.8
by kevin parks 26 Nov '03

26 Nov '03

Hi, I downloaded the pre-built package from www.pure-data.org and ran the installer. I let it install everything. I had Tcl/tk 8.4.4 already installed, but let the installer overwrite that with 8.4.1 since the site said that there pd "seems" to have trouble with 8.4.2 and 8.4.4. I am not sure what that is about. I'd wouldn't mind knowing if it does have trouble with it or not, "seems" is not a word one likes associated with software. It is like i "seem" to be bleeding from my head. Either you are or you ain't.... Anyhoo... Things are a mess. pd launches the wish sell and gives you the other little box for IO or whatever, but refuses to open any patches and when i try it just keeps opening shells but not patch to run or edit.... I tried opening through the menu but all my .pd files are greyed out. Someone please, i am begging, helping get this thing running, and also, is it at all possible to use GEM on Mac OS X and how do you do that? Any help would be appreciated -kevin--

ALSA, HDSP, Jack and Pd the walking dead
by Iain Mott 26 Nov '03

26 Nov '03

Dear list After shelving this project for quite some time, have just recently managed to get an hdsp/multiface setup running with ALSA and Jack - a miracle! However I have a couple of problems that i'll list below. I'm using Pd 0.37.0 configured for Jack, Jack 0.90.0, ALSA 0.9.5 (latest CVS snapshot). 1. When I quit Pd - the connection to jack doesn't seem to exit cleanly - I need to restart Jack. The actual sequence is this: a) start Jack with a conservative: "jackd -v -d alsa -d hdsp -p 1024 -r 44100" b) start pd with "pd -jack channels 8 -verbose&" c) get the following printout from Jack: new client: pure_data_0, id = 2 type 2 @ 0x40210000 fd = 12 registered port pure_data_0:input0, offset = 0 registered port pure_data_0:input1, offset = 0 registered port pure_data_0:output0, offset = 77824 registered port pure_data_0:output1, offset = 81920 ++ jack_rechain_graph(): client alsa_pcm: internal client, execution_order=0. client pure_data_0: start_fd=5, execution_order=0. client pure_data_0: wait_fd=11, execution_order=1 (last client). -- jack_rechain_graph() connect alsa_pcm:capture_1 and pure_data_0:input0 ++ jack_rechain_graph(): client alsa_pcm: internal client, execution_order=0. client pure_data_0: start_fd=5, execution_order=0. client pure_data_0: wait_fd=11, execution_order=1 (last client). -- jack_rechain_graph() connect alsa_pcm:capture_2 and pure_data_0:input1 ++ jack_rechain_graph(): client alsa_pcm: internal client, execution_order=0. client pure_data_0: start_fd=5, execution_order=0. client pure_data_0: wait_fd=11, execution_order=1 (last client). -- jack_rechain_graph() connect pure_data_0:output0 and alsa_pcm:playback_1 ++ jack_rechain_graph(): client alsa_pcm: internal client, execution_order=0. client pure_data_0: start_fd=5, execution_order=0. client pure_data_0: wait_fd=11, execution_order=1 (last client). -- jack_rechain_graph() connect pure_data_0:output1 and alsa_pcm:playback_2 ++ jack_rechain_graph(): client alsa_pcm: internal client, execution_order=0. client pure_data_0: start_fd=5, execution_order=0. client pure_data_0: wait_fd=11, execution_order=1 (last client). -- jack_rechain_graph() at this point, everything works fine - Pd produces sound on all cylinders d) quit Pd - no apparent problems here either. Get the following printout from Jack which hints something might be wrong, unkindly labelling Pd a "ZOMBIE": removing failed client pure_data_0 state = Finished errors = 0 adios senor pure_data_0 *&*&*&*&** senor pure_data_0 - you are a ZOMBIE DIS-connect pure_data_0:output1 and alsa_pcm:playback_2 DIS-connect pure_data_0:output0 and alsa_pcm:playback_1 DIS-connect alsa_pcm:capture_2 and pure_data_0:input1 DIS-connect alsa_pcm:capture_1 and pure_data_0:input0 ++ jack_rechain_graph(): client alsa_pcm: internal client, execution_order=0. -- jack_rechain_graph() load = 1.5981 max usecs: 305.000, spare = 22914.000 load = 0.8421 max usecs: 20.000, spare = 23199.000 e) start Pd again - starts up with a normal command line print out, however no patch windows can be opened and "quit" won't work. f) Jack by this stage has stalled before first printing out: new client: pure_data_0, id = 3 type 2 @ 0x40210000 fd = 12 registered port pure_data_0:input0, offset = 0 registered port pure_data_0:input1, offset = 0 g) Pd needs to be killed off with a "kill -9 pid" and Jack with a Control-C - resulting in a segmentation fault. Anyone else experiencing something like this? 2.The other problem is that Pd's DSP can't be properly switched off. The audio remains on and is heavily broken up. Switching DSP back on again fails to remedy this. Hope someone can shine some light on this.
