Re: [PD] drag and drop files in pd ?
hello,
the drag'n'drop tcl command is implemented for opening pd files, if you are
curious look for this code in pd.tk:
catch {
package require tkdnd
dnd bindtarget . text/uri-list Drop {
foreach file %D {open_file $file}
}
}
you will need to install tktdnd lib to try out this GUI feature.
It would be nice to have externals using this lib.

Re: [PD] ReacTIVision to Max4live (don't hate)
Hi, another way would be to use midi directly from the reacTIVision application. In the midi xml file you can define what data goes where, depending also on the fiducial. It is fairly easy to define which fiducial outputs midi 'knob data' to which channel. Then to receive this in Reaktor in Windows does require something like midiyoke. In linux jack and qjackctl are great for this purpose. This way you would not need Pd or max. Though it simplifies the output, and does not allow you manipulate the data, so that would depend on the exact kind of data you want to receive in Reaktor.

So far i've been able to register the TUIO messages in the m4l patch, but it doesn't differentiate between fiducials. I get errors that state $ variable out of range and extra argument, but the objects i'm using [send $1-tuioObjectAlive 0] were copied from the TUIO dispatcher maxpatch that the reactivision folks provide on their site. I realize that the problem may come from the difference between Pd and max, and the fact that Pd uses a message box to send out [$2-tuioObjectAlive 0] and max uses the [send] object. Any suggestions? P.S. Ultimately, the goal is to map the fiducials to the control knobs on Reaktor's skrewell so it would go like reactivisionM4LReaktor instead of having to do reactivisionPdmidiyokeReaktor, or is this the longer way around?

Re: [PD] Musical notation object on Pd
I don't know if you already see this website: http://music.columbia.edu/~alessi/ http://music.columbia.edu/%7Ealessi/ it has an e-mail but is very outdated... that mail bounced. it's current employer has his name on a list, but no mail contact. I still think you could do all the CAC 'logic' in Pd and use external tools for the music notation part. I could do it, no doubt about it, and I think that I will eventualy (I'm having some troubles with jack in my computer though, but that's another problem). Still, what I want is something to display the pitches inside Pd while I'm working with the algorithms, honestly, all those hacks are not as good as a tool like those from PWGL or OpenMusic. I know that Pd was not tought as a CAC program, but on the other side, It was not tought as a video rendering software either... I also agree. this isn't about rendering a score programmed in Pd, but working on the score at the same time one works on Pd. And for that it's necessary that both things work at the same time and can communicate with each other. One other detail that would be important is also the communication from the score to the patch. For example, trigger events by clicking in the score, etc. Don't get me wrong, all those ideas were very very helpful and I will try them, but since we are just talking about an (yet) hypothetical tool, I think we should consider what would be the best thing to have for that poupose. Pd has a lot of potential as a CAC tool (we are already doing it) and a notation display is something that I feel is essential for that task. As I said, this project seemed to me to be nice, and it's also at an advanced stage. http://sourceforge.net/projects/inscore/ ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Re: [PD] Musical notation object on Pd
that looks a nice beginning (I can't try it now). But I would say that in order to make a complete object, it should be possible to - render complex musical structures (including microtonal pitches, dynamics, articulations, rhythms, polyphony ...) - get instructions from pd and/or from other standards - musicxml, for example - use characters and fonts defined by the user - on top of the cherry, interact with pd as well - e.g. release messages when someone clicks on a note on the score, ... - whatever I'm not remembering now Since there are already some projects going through in this area (e.g. pwgl or inscore), wouldn't it make sense to try to integrate with these, or try to help them, instead of reinventing the wheel?

I know about non-techsavy classical players, I wrote the click tracker for them - http://puredata.info/Members/jmmmp/click-tracker. of course you shouldn't send any cryptical commands to anyone who isn't interested in getting them. But for example packaging inscore into the same folder as your patch, and starting it (it's a separate application) isn't that hard to manage in Pd, and not something that's hard to organise. as long as the patch works on its own, the players don't really care what's happening inside. you're free to do what you want, I would myself not even venture into such a project, because there are already several resources available that might be more efficient on doing the same (or even a better) job.

[PD] lowest latency ARM board for Pd
I'm curious about people's experience about getting low latency performance using Pd on ARM. From what I've seen Pd on iPod Touch/ iPhone is the best. Has anyone gotten solid 20ms latency from an ARM/ Linux board or phone? .hc All mankind is of one author, and is one volume; when one man dies, one chapter is not torn out of the book, but translated into a better language; and every chapter must be so translated -John Donne ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

I think I already wrote about it on pd-list this autumn, no...? But it's hard to search the archives about the frequency of that thread, as the keywords might not be consistent. I just know that the problem has existed for quite a few years and that I read about it on pd-list more than a handful of times. Indeed! I remembered it coming up and so I searched the archives before posting, but keywords like 'cpu' and 'usage' don't do very much. However, digging a little with Shark, I see that a high proportion of Pd's CPU time is spent talking with the audio hardware, so I try Google: DspFuncLib portaudio, and lo and behold: http://www.google.co.uk/search?q=DspFuncLib+portaudio Trouble is use jack doesn't solve the problem, it merely avoids it. So, zooming in a bit, I see at least two issues here: 1. there is a lot of activity in the underlying audio drivers when using the Portaudio driver on OS X, even when audio is off in the application. Let's call this the 'idle' CPU usage. IMO, this should be less than 1% on modern CPUs for well behaved applications. I've added this to the bug tracker. 2. there is a lot of activity in the underlying audio drivers when using the Portaudio driver on OS X, when audio is on in Pd. Comparison with AudioMulch, which also uses Portaudio suggests that is only in part a Portaudio problem. AudioMulch idles at ~10% on my machine. I suspect that the problem with Pd+portaudio may be due to a small buffer size used by Pd. I thought Pd's 'Delay' setting in audio preferences was supposed to handle this, but changing delay to 500ms, has no effect on CPU use. Also added to tracker. As far as I understand it, Pd only does the 20% idle thing when its not really doing anything. So if Pd is working hard, it'll stop spending 20% of the CPU idling. I could be wrong tho, and that would be worth profiling. That's the key point: is Pd efficient when its doing stuff, rather than whether it uses extra CPU when idling. .hc I have the audacity to believe that peoples everywhere can have three meals a day for their bodies, education and culture for their minds, and dignity, equality and freedom for their spirits. - Martin Luther King, Jr. ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

I don't remember whether I posted this before. It's an external that
doesn't define any classes, but installs a crash report handler that
prints to the terminal. It requires execinfo.h which is linux-
specific. It decodes C++ symbols using cxxabi.h (provided by
glibc). This means you don't need to run gdb to get a basic listing
of what happens. However you will still need gdb if you need to know
what the function arguments were.
If you run an older version of GridFlow (9.11 or earlier) you will
need to ensure segfault appears after gridflow in the Startup
menu. If not, the order does not matter (unless you need to trap a
crash at load-time).
