Compiling (CVS?) on windows
by Adam Lindsay 27 Nov '02

27 Nov '02

Hi folks. What tools are needed to compile Pd on Windows? Is it possible using the source code on CVS? Has this been written up before? I've been looking through the archives (and PdWiki) to no avail. TIA, adam -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Adam T.

undo crasher in 0.36-test9
by Adam Lindsay 27 Nov '02

27 Nov '02

Hi Miller, I'm seeing a fairly consistent crasher on the Mac, using a freshly- squeezed pd-0.36-test9. 1) create two objects 2) connect them 3) start changing the destination object by typing into it 4) stop typing mid-word (so that the name wouldn't be a legal object) 5) press undo sometimes it's a bus error, sometimes it's a segfault. Once or twice, an odd clone of the source object was created. Once, I got a slightly more helpful error: "Consistency check failed: glist_findrtext". Does this appear on NT or Linux? I tried to find the source of Frank's Text Editor non-function, but once I reached g_editor.c::canvas_key, I realised there's a whole lot I don't understand about certain of Pd's internals. :) But in looking at it, I learned that--at least in the current version of Tcl/Tk MacOSX--we're not getting keysyms from the arrow keys. That explains a couple things that Ryan mentioned earlier. I have a simple hack for the end of canvas_key that helps move objects around on the canvas. (Was planning on throwing it at CVS tomorrow morning.) adam -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Adam Lindsay +44(0)1524 594 537 atl(a)comp.lancs.ac.uk http://www.comp.lancs.ac.uk/computing/users/atl/ -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

Happens to me too on Linux. Kaboom! Will try to fix this and the "text editor" bog now... cheers Miller On Wed, Nov 27, 2002 at 12:56:28AM +0000, Adam Lindsay wrote: > Hi Miller, > > I'm seeing a fairly consistent crasher on the Mac, using a freshly- > squeezed pd-0.36-test9. > > 1) create two objects > 2) connect them > 3) start changing the destination object by typing into it > 4) stop typing mid-word (so that the name wouldn't be a legal object) > 5) press undo > > sometimes it's a bus error, sometimes it's a segfault.

line multicommand
by João Miguel Pais 26 Nov '02

26 Nov '02

In kind of continuation to my last mail about line, I remembered to suggest this change that might be useful: instead of only three possible instructions to line - immediate value, next value & duration -, it would be better to be possible to give only one command with already several instructions. That way, more complex envelopes could be created. I think max allows the entry commands to go until 255, that means several possible segments. João Miguel Pais

Heart rate and brainwave sensor
by arm pdlist 26 Nov '02

26 Nov '02

Greetings from Portugal. This is my first post, so i'll introduce me. I am a master's degree student in multimedia technology and i'm currently starting to work to my thesys. I will build a system that can react to a heart rate and a brainwave sensor. The system woud interpret those signals and create music and images/video according to that. I think that PD would be the ideal programming software for that. The main problem, and where i'm searching for help, is this: - do you guys knows about some sensors that i can use to measure the heart rate and brainwave? I've made a quick search over the net but i couldn't find anything. - how do i connect those sensors with PD? I suppose they will be connected to the computer via USB (my laptop only has USB ports) bu ban PD read values from an USB port? - I would be everything much easier if i could connect those sensors to a I-CubeX system, so i would only deal with MIDI data. Do you know any heart rate and branwave sensor that can be plugged to an I-CubeX system? The ideal scenario would be to have those two sensors to transmit MIDI data to a MIDI interface, but i don't know if this is possible. Thanks in advance.

pd, ALSA and Midiman
by shreeswifty 26 Nov '02

26 Nov '02

hi folks I spent the morning getting ALSA to work finally with my vaio laptop in linux i compiled the intel8x0 drivers and got them working after some struggles One must specify --with-kernel=/usr/src/linux & --with-moddir=/lib/modules/(kernel)/misc in the ./configure scripts for it to work (at least for me) then i had to do the same routine for snd-usb-audio i used the fxload .rpm from planet CCRMA and followed the directions on the alsa-project site (editing the ezusbmidi binary) and hotplugged it it works with mididev -2 now to get the emi 2|6 running with linux any tips :-) Pat Pagano, Director South East Just Intonation Society http://www.screwmusicforever.com/SHREESWIFT/ http://www.digitalworlds.ufl.edu

Re: [PD-announce] pd 0.36 test 9
by Adam Lindsay 26 Nov '02

26 Nov '02

Thanks Miller, This will compile on the Mac with one change: Change 'configure' such that the Darwin LDFLAGS are: LDFLAGS="-Wl -framework Tcl -framework Tk -framework CoreAudio \ -framework AudioUnit -framework AudioToolbox \ -framework Carbon -framework CoreMIDI" I don't want to delay you from getting on with the release, but there's a minor visual inconsistency brought on by undo and thick-lined signal connections: - Create a signal connection. - Delete it. - Undo. - Only a thin line reappears. The same happens with the converse (a redo of a connection). I've poked around with canvas_undo_connect and canvas_connect a little, and the solution isn't obvious (to me, at least). adam PS. I'm keen to throw a lot of visual/surface-GUI changes into CVS, anyway, if you want to leave this.

patch bay
by João Miguel Pais 25 Nov '02

25 Nov '02

Dear list, I am thinking about how to build a patch bay for a live-impro patch. For example, with 3 or 4 different input sources, and more 3 or 4 effects, one input source to be connected with several effects in series (input->fx1->fx2->...). The ideia would be that like on an analog patcher, it would be easy to make fast changes between (radically) different setups during performance. For this to work, all audio signals (sources and effects) would have to go through the central router. I was trying this with multiplex~, but it does not allow feedback inputs - when something which comes from it's output is connected to the input, the object switches off processing: for example osc~ -> mux~ input 1 -> freeverb~ -> mux~ input 2. Lacking of more ideas, I am thinking of keeping the connections window on edit mode, and edit them manually during performance just simply by putting the wires on and off, like an analog version. It won't be so fast and efficient. Has anyone thought / developed something similar before? João Miguel Pais

connection output order & multi-line & multidial
by João Miguel Pais 25 Nov '02

25 Nov '02

Is it possible to eliminate the feature by which the order of the output messages (when one point has several outputs) are sent? This can be useful in the beggining, but in the next day (or hour) one does not remember already the output order, and can lead to some very annoying problems. Maybe it is preferible to use trigger and everything is clear the next time the patch is opened, as to the current situation. (or in other words, to work as in max) (if this is not clear, it is the feature explained in file 03.connections.pd) Or is this feature already out in the latest versions? Another question: is there any kind of multi-line object - a line that accepts more than one segment? (like csound's linseg) In the libraries I have here (the main ones) couldn't find any. question 3: is there any kind of dial object, but which allows more than one square to be active? Or the choice is to put several toggles in pilled up? João Miguel Pais
