end of the vline~
by Scott Fitzgerald 08 May '08

08 May '08

I feel this is a head-slappingly stupid question, but is there any way to tell when vline~ has finished its run? like a bang at the end, or something? i am feeling quite dense right now. (ditto with line, or line~) thanks ~s

doepfer pocket electronic & pd
by alexandre r. decoupigny 08 May '08

08 May '08

hey all, has anyone ever had any experience with sending data from the doepfer PE board to pd via midi ? i connected a uno midinterface to the midi out via usb and i dont know how to read the data into pd.. neither the notein or ctlin seem to receive anything.. im on mac osx 10.4.4. on the other side of the PE there are 8 faders connected to the board because i basically want to use it as a midi controller for ableton live. its a very pretty thing .. you can see it here: http://listeningart.blogspot.com/2007_09_01_archive.html thanks : ) alexandre -- alexandre r. decoupigny www.listeningart.blogspot.com www.myspace.com/alexandredecoupigny

OSX-intel extended Audiio droputs
by Luigi Rensinghoff 08 May '08

08 May '08

Hi List i am quite desperate....;-( Working on areally nice patch with boids and sound. I have the latest available OS-X extended for Intel, which is still from nightly autobuilds (20080505), because it has a working boid3D external. There is pmpd and Gem involved but the load meter is only a 30 percent. After about 7 seconds of running the patch (no Gui-elemnt or number box running) i start to have nasty crackle sounds. I have no idea where they come from....i put the delay to 100 ms and the -rt audioflag... patch is attached If anybody has an Idea ??

add masses in msd
by marius schebella 07 May '08

07 May '08

hi, I am running into a new problem with msd, I want to create and delete masses on the fly, and every mass has to be linked to all existing masses to do bouncings. right now I don't have a good solution yet to keep track of id's and tend to use python for this. but I had another idea, maybe someone has a comment on that. let's say all my masses are named m, then I want to add a mass with name m-new, I could link m m-new, and would get a connection from every old mass to the new one. all I needed to do then is rename m-new to m, which is not possible right now, but should not be too difficult to implement. it is relatively easy to look up one mass in a table, and delete it, but it is not very fast to search for all existing masses (in a list). of course I could also use pmpd and an interactor... thanks, marius.

Hello list! Here's jon~, a reverb abstraction based on the algorithm in this article by Jon Dattorro: http://www.stanford.edu/~dattorro/EffectDesignPart1.pdf The allpass bit was taken from pd-list and the help file is copied from Millers rev3~-help and then modified a bit. Any feedback is appreciated. /Anton http://www.hornquist.se/pd/jon

Re: [PD] OSX-intel extended Audiio droputs
by Matt Barber 07 May '08

07 May '08

Hello, Please run "top" from the command-line as well to see how much CPU PD is really taking up. On our macbooks here, and also on our G4 powerbook, both PD vanilla and extended have been running at about 50% CPU just by loading the program, but that isn't shown in PD's load meter. We have had some success with turning off airport - in some cases we get back down to 5% or so just having PD running with airport disabled. There were some posts over in the supercollider list about the same problem -- running 70% CPU just by booting the server, but then having some success (down to 1%-2%) once airport was turned off. Are you on a laptop? If so, it's at least something to try.

direction
by Ben Carney 07 May '08

07 May '08

hello all pd-ers not quite sure how to hrase this correctly. I need to be able to dtermine direction of a string of bangs. more sinply, I need to know if they are being triggered in the same direction from which they started, or if they are bing triggered in the opposite. i need positive or negative numbers respectively. stripping what i have to the bone is this: [ hslider ] [route 1 2 3 4 5 6 7 8] | | | | | | | | o o o o o o o o | [other things] } | } [that give me] } | } -----this stuff is all working well [positive numbers] } | } [independent of direction] } | [number] I need to be able to tell direction the slider is being "slid" relative to the direction it started from. hope i am being clear. many thanks in advance -- Ben C.

Thanks. I'll look into this - I havent tried the patch in any other samplerates. There's some text in the patch that may be confusing, though, cause it's only a reference to the figure in page 3 of the PDF article. For example [pd z^-4453] is not a sample-wise delay of 4453 as one would expect. It's a subpatcher with delwrite and delread 149.625 milliseconds. I got this by dividing 4453 by sample rate 29761 Hz (4453 / 29761 = ~0.149625) as stated in the table on page 4. I hope this is correct, I'm not sure. :) I think I'll change the "pd z^-4453" text to avoid confusion anyways. /Anton

recursively search directories for abstractions
by Matt Barber 07 May '08

07 May '08

Hello again, Is there an object that gets PD to search directories for abstractions, without resetting the -path flags on startup? And is there any way to do so recursively? I create an abstraction, say [frac] which returns the fractional value of a float. I have an abstractions directory called "mbarb", and inside that a directory called "math" where I want to put [frac]. I then want to be able to send my patch to a friend, with the mbarb abstractions, and have the patch load them automatically -- (I would prefer [frac] to [mbarb/math/frac] ..) Is there a way to do this, and if so do you know offhand after which version this became available? I have heard much talk about [declare], but I have not tested any version of PD after 0.39, and it doesn't seem to work there or before, unless I'm doing something wrong. Thanks again, Matt
