[Gem] separator fix
by Georg Holzmann 29 Aug '05

29 Aug '05

Hallo! I currently always get this message in Gem (each frame): ... separator : state->numTexCoords 4 != m_state.numTexCoords 0 separator : state->numTexCoords 4 != m_state.numTexCoords 0 separator : state->numTexCoords 4 != m_state.numTexCoords 0 ... my patch looks like this: | [separator] | [color] | [translateXYZ] | [scale] | [pix_buffer_read xxx] | [pix_texture] | [rectangle x y] I can see in the source code of separator.h: --------8<---------- //this is a partial fix for the separator memory leak // //if the texcoords are of equal number, which they almost always are //then just copy them in a loop without delete and new being done // //when texcoords are not equal the memory leak happens as usual ------->8----------- does this mean, in my patch there will be a memory leak (or is it just a debug post) ? Thanks, LG Georg

INSTALL.txt of pd
by Georg Holzmann 29 Aug '05

29 Aug '05

Hallo! It's maybe a minor issue, but I did it wrong again and again (copy-paste-error), so I wanted to post it: In the INSTALL.txt of the official pd is the following line: [...] type "./configure", possibly adding flags as follows: [...] To put Pd in /usr/bin instead of /usr/local/bin, add "--prefix=/bin". [...] which should be "--prefix=/usr" of course! LG Georg

More new data structure stuff
by Frank Barknecht 29 Aug '05

29 Aug '05

Hi, sorry, can't stop with this: Attached is more DS fun, this time using the quantized, restricted scaling or "grains" as they are described in the changelog. Promises to be great for making little sequencers for german techno. ;) Latest Pd from CVS or Miller's site required.

gumstix bluetooth tips
by Zachary Crockett 29 Aug '05

29 Aug '05

In the next few weeks I'll be creating an interactive sensor project with a dancer/choreographer involving a gumstix basix 200f-bt ( http://gumstix.com/spexboards.html#f )... venturing into hardware is going to be a new adventure for me and a challenge I'm sure... so I have 2 questions: 1) how to get bluetooth data into Pd? In the list archives someone said bt looks like a serial port and can be grabbed with [comport] ... simple as that? haven't looked really hard yet at the arguments & messages it takes since I don't have any hardware to test with yet -- anything obscure I should know? or is there a better way? 2) if anyone has experience using gumstix or something similar and can offer tips, I'd welcome the help -- I'll be wiring flex sensors into the 60-pin Hirose connector (fingers crossed) Cheers, Zac PS - mac os 10.4, g4, pd-0.38-4-extended-rc1 (planning to upgrade soon)

HID and timestamp
by etienne deleflie 29 Aug '05

29 Aug '05

Hello, I'm getting stuttering data output from my wacom tablet using the latest HID. stuttering .... I put a [timer] on the output of the abs X position messages, and discovered that the HID object spits out around 4 X position messages in one go ..... i.e. without any time delay. I've got a patch where you can really hear this (it is using a vd~ to do a dopler effect on ambisonic spatialisation stuff).... if I do a straight consistent line on my Wacom, the output comes out all stuttery and spitty.... and I have traced the reason to the fact that (around) 4 messages get spat out at once. NOTE: changeing the poll value of the HID object does not aleviate the problem. I concluded that this is what the timestamp (inlcuded in the USB messages) is for.... right? .......... the USB driver _or_ the USB device( I dont know about these things) instantaneously spits out 4 X positions and includes the timestamp between them.... so it should be (by using those timestamps) possible to get PureData to space out those 4 messages in time and hence get a smooth data line. do I sound like I dont know what I am talking about? does anyone want to educate me?

pool instantiates but can't create
by David NG McCallum 29 Aug '05

29 Aug '05

Hello all, Thomas, Changed distros a while ago, hadn't actually tried to do anything in Pd until recently. Using pool gives me the output: pool 0.2.0 - hierarchical storage object, (C)2002-2004 Thomas Grill pool ... couldn't create Er... any idea? pd 0.38-4, pool from Thomas' web site, Flext from planet CCRMA, whichever version that is. I hope the answer isn't "upgrade everything". cheers, David -- __ _ _ _ _ __ ___ _ _ __ _ ___ ____ _ __ __ __ _ __ __ To talk about it is to miss the point http://sintheta.org

Re: [PD] A mute device
by Chuckk Hubbard 28 Aug '05

28 Aug '05

Aha, 'spigot' is the object I've been searching for. The purpose of the "set set $1" was to prep the change object with the new value before reinitializing the receive, so that the value doesn't jump when unmuted, so the "set $1" is still necessary. The rest of the patch looks up a note name according to y, which I only want it to do when manually dragging notes. Thanks!

It is not illegal, but personally I consider renaming receives in GUI objects a last resort, as this makes reading and understanding patches much, much harder and can lead to subtle logic errors. For example I had a rather hard time figuring out what your patch is supposed to do by looking at it, until I opened all GUI objects to find the one which has the "raty" or "nothing" receive. In your patch it is not necessary to make things so complicated. Using a [spigot] makes everything much clearer, at least accoding to my taste. Also your "set set $1" construct could be replaced by a simple [f] where you can use the cold right inlet to store a number without outputting until a bang arrives at the hot left inlet. I illustrated this in the attached patch based on your previous mute.pd Ciao -- Frank Barknecht _ ______footils.org__

object using a thread?
by Christian Klippel 28 Aug '05

28 Aug '05

hi all, is there any simple object that creates and uses a thread, and which is cross-platform between at least linux, os-x and win? and if not a simple, is there any other? or has someone such a "bare-bone" object at hand maybe? goal is to make the object for the multIO threaded, so it would be just a simple reader-thread that toggles/writes to two message queses (one writing, the other reading) thanks in advance, chris
