GEM to SVG/EPS/PDF
by timon 23 Sep '07

23 Sep '07

Hi, I came across this, GL2PS: an OpenGL to PostScript printing library. If it could be incorporated it would make a great addition to the Gem. Dont know anything on how to build PD objects though (sorry, sounds a bit arrogant). Anyway, if its of interest. http://www.geuz.org/gl2ps/ Timon

pd-ext 39-2 rc4 (deb package) crashing with gop editing
by Kevin McCoy 16 Sep '07

16 Sep '07

Hi Hans, I think that this version is crashing when I edit a patch that uses gops, and then close the window - it asks if I want to discard the changes, and I click yes, then it closes out pd entirely. This only appears to happen when the main patch involves gops - not when it's just regular objects I think. I don't think I noticed this with rc3 - did you ever answer my last question (sorry if it didn't get through to you) which was whether this debian packaged rc4 included code updates over rc3 or whether it is rc4 by virtue of being a deb package alone? The package is totally sweet, it integrates so much more nicely in the system, but I am restarting pd a lot these days because of this little bug ;) I am working almost exclusively with gops now. Is there a log or a way I can maybe give you some more useful info aside from my personal testimony? Can anyone else verify this? Kevin -- ++++ http://pocketkm.blogspot.com

Bug in Pool?
by Luke Iannini (pd) 31 Aug '07

31 Aug '07

Hi Thomas (and list), I have run into what appears to be a limitation with [pool], namely that it crashes with something around ~780 characters loaded from a file as values in a key. I ran into this loading a particularly long list in Memento. I've attached a patch and a file from which to load to experience the crash. The file is just a little over the character count needed to crash it (it seems to be between 780 and 800?). It does not seem to be a function of the number of elements in the list, but rather the length of the text in those elements. Shorten a few of the values in the list and it loads right up. I'm also pretty sure this is a per-key limitation, as memento's lddir first loads files into /tmp before copying them into the proper key. I've used that with a file that was just under the crashing length and that worked fine (loaded into two keys). I have tested this on both my PPC Mac and my Intel Mac; maybe others can check it out too? (also to clarify, the problem occurs when loading data from a file; data of any length (that I've tried) makes it into the pool without issue, and saves without issue) Thanks! Luke

VST for audio network
by João Miguel Pais 21 Aug '07

21 Aug '07

Hi, can anyone recomend a good VST plugin to send audio data through a local network, with good audio quality and low latency? Something that could be used with PD/Max-MSP (or basically any program who uses VSTs) in both XP and OSX, for an improvising laptop trio connected through a local network (router, not internet). I was looking at tubePlug - http://t-u-b-e.de/iplug.htm -, but there seems to be a standard 1sec (!) latency, even when opening both server and sender in the same computer. But besides that, this plug-in seems to have potencial. After contacting the author, he seemed interested in adding a variable latency parameter, but who knows when it will be implemented.

[gem] interacting with objects
by victor 20 Aug '07

20 Aug '07

Hello, I'm testing with a patch for move objects in the gem render screen, using mouse. In adjunt you have a simple example I'd like: - Each object have a control surface, for example, a rectangle or square. If mouse is over active surface, we can do the interaction. - to have a index for each object. When I click on some control's square, I have the index of object active. That is more complex if we work in 3D or exist overlaping in several objects Right now, I have this troubles (with adjunt's patch): - Object clicked jump for to have center in mouse position. - If we move fast the mouse, we lose the object - I need a general work with position of mouse, not only relative to a size of screen are there some general patch for work with interactions? Thanks

24bit on Linux Indigo IO
by Mathieu Bouchard 13 Aug '07

Have you tried any others? > but I get a decimated mess using PD - sounds like a 24bit DAC playing > back a 16bit word... Does that mean just lower quality or does it mean playing some seemingly-garbage sounds at very high volume and very high pitch? The very high pitches would be related to 1/3 of the sample rate, but in the case of 96 kHz that's clearly ultrasounds, and with 48 kHz that's on the limit of ultrasounds. Most likely you would instead hear moiré between that pattern and lower-pitched patterns. I've never really heard 16/24 bit misinterpretation so I'm guessing. Do you get any console messages and/or terminal messages about number of bits? _ _ __ ___ _____ ________ _____________ _____________________ ... | Mathieu Bouchard - tél:+1.514.383.3801, Montréal QC Canada

counter question
by Derek Holzer 01 Aug '07

01 Aug '07

If I use a simple counter structure that continues to generate a number from [f] & [+1] at every bang, and use [mod] to keep that number within certain bounds, then eventually it will require more and more memory to hold the number coming from [f], right? Is this a potential memory leak, or is there a cap to how much memory it will hold? Likewise, is there a max limit to the number that can be stored in [f]? I've seen that [f] resets itself somewhere around 8.394e+06. Does that mean that [f] resets itself and clears the memory? Or in less-theoretical and more practical terms, would it make sense to reset [f] to 0 every so often, or let it run forever towards infinity? best, d. -- derek holzer ::: http://www.umatic.nl ::: http://blog.myspace.com/macumbista ---Oblique Strategy # 37: "Convert a melodic element into a rhythmic element"

Re: [PD] OSC between win and mac
by Marko Timlin 31 Jul '07

31 Jul '07

solution found, now it´s working. solution: first we gave in manually the IP numbers in the Windows as well as in the Mac machine. sendin to Mac was impossible. but using the IP numbers, which the machines automatically assigned to, solved the problem. it is also the case that these numbers are just one number away from each other. thanks especially to IOhannes for help and patience. ciao tutti Marko Timlin wrote: > Aaaaaaaaaaaaaaarrgghhhhhh, > I send and SOS to the world, I hope that someone get´s my...message in a bottle. > > still fiddling around with that bl##dy OSC connection form Windows to Mac or Pd to Max respectively. > > Status: > firewalls are off > sending OSC from Mac using Max to Windows using Pd works just fine > sending OSC from Windows using Pd to Mac using Max doesn´t work, I receive the following message: > SendData::SendHTMSocket()failure -- not connected > > to receive I use the dumpOSC object to send I use the sendOSC object. > I give in the IP number of the Mac and its port, but...nothing :-( > > by the way, sending and receiving OSC from Pd to Reaktor on Windows works also perfectly. honestly, have you tried to find out _where_ the error is (the mac, the xp box, the network) as suggested in previous mails? probably i have overlooked this in sos... can you connect from mac to mac (localhost)? can you connect from xp to xp (localhost)? (ok, you tested this!) what is inbetween the 2 machines? another firewall? (a real one, not a "personal firewall" nonsense) have you tried installing Pd on the mac and see what it gets? do you have other machines available for testing? have you tried other ports? are you sure that both objects are working in the same protocol (UDP). you could try to find some cmd-line tools for sending (and receiving) messages. again: "netcat" is the swiss army knife for _anything_ network related. it will allow you to fake both a server (netreceive/dumpOSC) and a client (netsend/sendOSC). mfg.asdr IOhannes

Newbie question: Highest number
by Alex Lucas 31 Jul '07

Hi all, I've been looking for an object or abstraction which gives the highest and lowest value from a stream of numbers. If anyone has any suggestions it would be great to hear from you. Many thanks Alex
