another attempt at pdp quicktime support on Mac OS X
by Hans-Christoph Steiner 13 Jun '07

13 Jun '07

Hey, I think this time it's for real! Please try out the pdp_qt and pdp_yqt on Mac OS X. I found a bug in the libquicktime embedding that I have fixed. http://autobuild.puredata.info/auto-build/2007-06-13/ .hc ------------------------------------------------------------------------ ---- News is what people want to keep hidden and everything else is publicity. - Bill Moyers

switch~ & cputime climbing
by Phil Stone 13 Jun '07

13 Jun '07

Hi, I'm getting a slow-but-steady climbing CPU when running some synthesis patches. I (like the poster below) have sub-modules that can be switch~ed on and off. An archive search turned up the following un-replied post: > Hi all > > Okay. I'm stumped. > > Recently, I've noticed that my cpu meter has been steadily rising. I > think I may have found the culprit. > > A while back I thought I'd put a power switch (just a switch~ object) > on my poor-man's granular delay line, as my performance patches are > getting a bit bulky. > > Try this (if you have the time): > > http://www.sideshowmedia.ca/cputest.zip > > cputest.pd: (needs expr, but I think that's all) > > 1. turn on audio in pd, but leave the power (p toggle) in "lois" > off.

I'm currently running 0.39.2-extended RC1 on a MacBook Pro. Phil Stone

alternate values per change?

So you need to put the [mod 2] within the loop so that values never get too high. as I said on the #dataflow chat, you can use [f]X[==] instead. I also suggested just using [tgl]. > Note: the first outlet of [sel] is ignored. "ascii-art" is very dependent on font width, and as a result, almost everybody who uses that, also switches to a monospaced font, in order to be sure that everybody sees it the same. _ _ __ ___ _____ ________ _____________ _____________________ ... | Mathieu Bouchard - tél:+1.514.383.3801, Montréal QC Canada

Question about possible SQL/MySQL Externals
by Mike McGonagle 13 Jun '07

13 Jun '07

Hello all, I was wondering if anyone had thought of creating an interface set of externals for storing and retrieving data from a Database? Basically, I was interested in seeing if anyone has created some externals that do basic SQL transactions. Or is this something that is not very practical? Mike McGonagle If you think you can, or you think you can't, you are probably right. —Mark Twain

alternate values per change?
by PROTMAN 13 Jun '07

13 Jun '07

I am sending a value of 0 and 1 toward a midi ctlout. When my button is pressed down, it sends 1, when it is up, it sends 0. I want this to instead alternate values so that when pressed down it sends 1, when let go, it stays at 1, when pressing again it sends 0, when letting go it stays at 0.. any ideas? thanks!!

Is there an Object in GEM...
by Mike McGonagle 13 Jun '07

13 Jun '07

Hello all, I was wondering if there is an object in GEM that will allow Pixel level addressing in a "Pixie" (that is what GEM calls images, right?)? I know there is a way to create an entire image from a list of numbers, but that only appears to do a complete images, and not addressable at the pixel level. If this is NOT possible, is there some other object/external that will allow the display and manipulation of images at the pixel level? Thank you, Mike M

netsend in localhost --> i got "netsend blocked N msec"
by moritz 13 Jun '07

13 Jun '07

ei lischt i'm working with two pd instances on one computer (übüntü feischty, p4). one pd with audio with higher priority, one with Gem/noaudio. i communicate between this two instance with one netsend/netreceive and i send a lot of data, and sometimes i got "netsend blocked N msec". is this a buffer-problem in the objects [netsend/netreceive] or is there an intern bandwidth bottleneck? or something else? thanx for helping moritZ
