Is this a MidiYoke or a PD bug?
by matteo sisti sette 20 Nov '07

20 Nov '07

Hi, The subject line of this message may recall another similar one I posted recently, but this is actually a different question (different bug). The attached patch periodically sends a burst of N midi control changes with a random value, control number 1 and channel 1. Let T be the time period, i.e. right input to the [metro]; N is set through the message box in the patch. Now, I select MidiYoke 1 as the output midi port, and I open another instance of PD with MidiYoke 1 as the input port. In this second instance of PD I create a simple patch with just a [ctlin] and three number boxes connected to its outlet to see what it receives. With reasonable values of N and T, all works fine, and on the receiving side I always get 1 as the control number and channel, and a random control value. But if I set T to very small values and N>1, namely when N/T>4, every once in a while on the receiving side I get a control change with "103" as the control number, and 0 as the value (still channel 1). I have been playing around with N and T and I seem to get coherent results, in that the errors happen when the ratio N/T is greater than a certain threshold, in my case 4. For example, N=4 and T=1, or N=8 and T=2, will trigger the bug. Has anyone ever experienced a similar issue? Do you know whether it is a bug in MidiYoke or in PD? Obviously I recognize that sending more than 4 midi messages per millisecond fron an application to another one is too much, and I don't expect to be able to do that as an average rate for a long period of time. However, suppose I send midi events at a fairly reasonable *average* rate but every once in a while I may get a burst: it's a serious issue if in those cases you can get unpredictable and undetected errors.

precise milisecond/second counter
by ilya .д 20 Nov '07

hello list. i was terribly surprised the way [metro] behaves - checking it agains [timer] of coruse doesn't give any latency ever! but with [realtime] and [cputime] - the result is is far from acceptable and even unproportional, (icresing twice doesn't give any aproximatable result). how ever the system load was quite hight - /proc/loadavg: 3.29 3.31 3.54 6/268 22074 and even > 5.0 at some point.. i run linux 2.6.20 with built in RT_MUTEX .. i never noticed any latency while interacting via gui.. how ever there was a bit of acceptable audio latency when i was programing some effects using live input and comparing to pd's streight wire from adc~ to dac~ (inside a busy patch) there was a noticable delay .. however i assumed [metro] to be closer to ideal , really .. so i have actually made a patch which give a very precise ticking. please have a look .. -- cheers, ilya .d

[GEM] pix_artoolkit
by Johannes Taelman 20 Nov '07

Hi, Does anyone have a help or example patch for pix_artoolkit? I have pix_artoolkit running, but haven't coordinated the transform of a 3d object yet - which is probably already patched by someone? thanks, Johannes

[Csnd] Writing subpatch contents
by Chuckk Hubbard 20 Nov '07

20 Nov '07

I believe the question of saving automation data has come up before, but this is a different question, I think. I want to write and read the objects in a subpatch to and from textfiles; not the state of the objects, nor scalars, but the patch itself. Is there a way? I have 8 voices in my sequencer, and 8 subpatches for creating control values to send to csoundapi~. But each Csound orchestra I work with will have different parameters for different instruments, and so the 8 will be different from each other, as well as being different depending on what score I open in my Pd sequencer. So I gave up on using abstractions with arguments, because whenever I change one they all change. But AFAIK subpatches can't be read and written by sending messages to them. Any ideas? Is there a 'menusaveas' message or something? -Chuckk -- http://www.badmuthahubbard.com

who is using [entry]?
by Hans-Christoph Steiner 19 Nov '07

19 Nov '07

For the next step in the tkwidgets library is converting [entry], which I have done a lot of work on, to [text], following the Tk widget name. (It turns out that "entry" is a different Tk widget). Now I am going to apply what I have learned to a how library based on the Tk widgets. I am naming them after the Tk widgets, so that would mean making an object called [entry] with is a text entry box, and renaming the currently [entry] to [text]. I am wondering how much people use the old [entry]. If not much, then I think the easiest path forward is to remove [entry] from flatspace and maybe stick it in "deprecated" or a "bbogart" lib. .hc ------------------------------------------------------------------------ ---- "[W]e have invented the technology to eliminate scarcity, but we are deliberately throwing it away to benefit those who profit from scarcity." -John Gilmore

[Pd] How to load/save subpatch content dynamically
by Chuckk Hubbard 19 Nov '07

19 Nov '07

This patch will load subpatches from existing .pd files. Actually, it copies them. Requires zexy. Seems crazy that it takes this many objects to do it, but this is the simplest way I could find, due to some of the little idiosyncrasies of Pd. I'll post a reply soon with another to save subpatches to .pd files (to copy them back). If it works, it should be possible to dynamically save and load the content of subpatches externally. If anyone knows a simpler way, please tell me. Does not work completely with .pd files containing the [csoundapi~] object, FYI. I think it ends up pasting the clipboard into tabularasa before completely loading the patch. Anyone know how to skip over the "Close this Window?" message? Maybe sending key messages for Ctrl-Shift-w? -Chuckk -- http://www.badmuthahubbard.com

floating point exception (core dumped)
by altern 19 Nov '07

19 Nov '07

hi I just added a spectrum visualization to my patch taken from example E01.spectrum.pd . Activating this causes my patch to crash after a minute or so of use. From then on the patch itself seems to be damaged and i cannot open it any more. I get "floating point exception (core dumped)" error and pd quits as soon as it opens. I never had such a problem with PD. Reverting the patch to a version previous to the patch does solve it. However, they should be identical because I dont change anything. As far as I remember there is no array with "save contents" option active so I dont really know what is different in the patch after the crash. I am running Ubuntu Gutsy, with PD extended0.39.5-extended-rc5 on a IBM x32 with P4 1700mhz any idea what might be causing this error? thanks enrike

Fwd: Bug entering '{' characters WAS: who is using [entry]?
by Mike McGonagle 18 Nov '07

18 Nov '07

Hans, Last night, I think I found a problem with [entry/text]. Basically, any time you enter a '{' that gets passed onto PD, PD will lock up... the widget still works, but the only thing that works in PD is the Quit menu under the Application menu (not the file menu, I am on a Mac). I attached a patch for your amusment... Mike
