alsamidi message?
by Dan Wilcox 26 Jul '08

26 Jul '08

Is there an internal message to tell PD to open it's alsamidi ports in Linux? Ever since the upgrade to Ubuntu Hardy, the alsamidi startup flag no longer works. I opened a bug report on it if I'm not alone. Thanks. --- Dan Wilcox robotcowboy.com

last call on Pd-extended 0.40.3-rc4!!
by Hans-Christoph Steiner 25 Jul '08

25 Jul '08

It looks like there are no more show stopping bugs on Pd-extended 0.40.3, so I think this is the one to release! Please test your patches with this version, things should all work, or there is a problem. http://at.or.at/hans/pd/installers.html Once this is released, then we can move on to new features and, of course, fixing more bugs. :D .hc ------------------------------------------------------------------------ ---- "It is convenient to imagine a power beyond us because that means we don't have to examine our own lives.", from "The Idols of Environmentalism", by Curtis White

GEM and GeForce4 MX 64mb
by smills＠rootsix.net 25 Jul '08

25 Jul '08

hi I thought i would give GEM a go last night and it seems really cool...probably an understatement! :) One thing, i set the antialiasing on with [FSAA 4( and it works, except that the top left quarter of the gemwin is all glitchy - literally like a square portion of garbled looking mess with polgons missing. The rest is absolutely fine. Do i need to adjust settings somewhere, or is my gfx card not up to it? I've never had problems with it before. This is on a Pbook g4 1ghz, GeForce4 MX mb, os x 10.4.11 many thanks

Re: [PD] midi clock receive/transmit
by mami music 25 Jul '08

Hi david I made this patch along time ago to send midi clock to a drum machine. Worked fine, but have not reviewed it since. The secret is in sending the correct midi start and midi stop messages. also the relatoin between the frames and the bpm. Nthing special really. I have not had the time to checkit now so probably youll have to make xome ceaning. Hope it works Daniel 2008/7/25 David Schaffer <schafferdavid(a)hotmail.com>: > Hi guys, > > Can anyone tell me how I can send/receive midi clock information > from/to hardware devices?

Re: [PD] request assistance with crackles and pops in VFOs, driven by modulating accelerometer signals

A good idea to improve that anyway, and I did, however there is no obvious audio improvement. hard off also wrote: > by the way, is it even possible to get clicks when rapidly changing osc~ > speeds? i didn't think it was, and i have never experienced that. Precisely why I am "bamboozled", it may well have another cause in my wider synthesis system. (I have used a quite similar accelerometer audio synthesis system for years in JSyn without this trouble). Thanks for taking the trouble to consider my situation and challenge my assumptions, appreciated, I'll keep looking/listening, and try breaking things back down to a very simple test suite first, Darren -- Darren Kelly, BSc, PhD phone: +61 (2) 9386 0090 post: PO Box 1816, Bondi Junction, NSW 1355, Australia http://www.webel.com.au

Pd-0.39.2-extended-rc4 released
by Hans-Christoph Steiner 25 Jul '08

25 Jul '08

http://at.or.at/hans/pd/installers.html It's looking quite stable, so please try it if you haven't already so we can find the last bugs. As far as I know, there aren't any outstanding bugs that need to be fixed for this release. Test away and file bugs in the bug tracker! http://puredata.org/dev/bugtracker (the Mac OS X 10.4/Intel build is not up yet, and will hopefully be up tomorrow). .hc ------------------------------------------------------------------------ ---- "It is convenient to imagine a power beyond us because that means we don't have to examine our own lives.", from "The Idols of Environmentalism", by Curtis White

schedule a sequence of events
by altern 24 Jul '08

24 Jul '08

hi i needed to schedule a sequence of events, in this case start/stop certain parts of a patch over time. I wanted to be able to pass to an abstraction a list of time intervals (in secs and with variable length) and then get output a series of bangs after each of the intervals. I attach the solution I found, not sure if this is clever or there is maybe something already done for this? I use drip, coll and delay. It receives a list of times like 2 3 0.5 and outputs the index at the right time. In this case after 2 secs outputs num 0, after 3 secs num 1, and after half a sec more outputs num 2. I called it sequence but i bet this name is already taken and it would be wise to rename it with another one. thanks for any feedback or ideas enrike #N canvas 328 332 784 519 10; #X msg 144 366 next; #X msg 97 201 clear; #X obj 31 218 drip; #X obj 31 261 i; #X obj 58 261 + 1; #X obj 31 239 t b f; #X msg 46 193 0; #X obj 31 326 coll xxxx; #C restore; #X obj 58 391 delay; #X obj 31 282 pack f f; #X text -2 388 index; #X text -2 350 time; #X obj 33 391 f; #X msg 138 201 stop; #X obj 31 351 * 1000; #X obj 14 170 t b l b b; #X text -35 198 wait; #X obj 33 451 outlet; #X obj 14 80 inlet; #X obj 97 170 t b b; #X obj 178 102 tgl 15 0 empty empty empty 0 -6 0 10 -262144 -1 -1 1 1; #X obj 58 414 spigot 0; #X msg 166 71 1; #X obj 178 19 inlet; #X msg 65 38 0.5 1 2 3; #X obj -35 218 delay 50; #X connect 0 0 7 0; #X connect 1 0 7 0; #X connect 2 0 5 0; #X connect 3 0 4 0; #X connect 3 0 9 0; #X connect 4 0 3 1; #X connect 5 0 3 0; #X connect 5 1 9 1; #X connect 6 0 3 1; #X connect 7 0 14 0; #X connect 7 1 12 1; #X connect 8 0 21 0; #X connect 9 0 7 0; #X connect 12 0 17 0; #X connect 13 0 8 0; #X connect 14 0 8 0; #X connect 15 0 25 0; #X connect 15 1 2 0; #X connect 15 2 6 0; #X connect 15 3 22 0; #X connect 15 3 19 0; #X connect 18 0 15 0; #X connect 19 0 1 0; #X connect 19 1 13 0; #X connect 20 0 21 1; #X connect 21 0 12 0; #X connect 21 0 0 0; #X connect 22 0 20 0; #X connect 23 0 20 0; #X connect 24 0 15 0; #X connect 25 0 0 0; #X coords 0 -1 1 1 95 19 1 100 100;

Save RAM memory usage ?
by Solen Music 24 Jul '08

24 Jul '08

I'm looking for a way to shrink the RAM usage in my live patch. I'm currently running a patch for live usage which has 14 x 100 stereo audio arrays. and 14 x 20sec variable delay lines. there's also 3 vst plugins (compressor, limiter and tape style delay). the GUI isn't too busy, there aren't any vu's and the arrays and lots of stuff are hidden in subpatches. it is basically a 7 stereo channel (hence 14 x 100, 14 mono pairs x 100 clips long in timeline) ableton live-esqe system but with a delay line on each channel (i need different delay times each channel, hence no send setup). I have initialised all arrays to 6 samples (which i suppose i should change to 1 or 0 samples if possible). So that they take up the minumum amount of RAM when not in use (correct me if i'm wrong). i have a loop programmed that loads the audio files into the arrays and resizes the ones in use. they are 16 bit stereo files The most amount of arrays I've tried to load into the patch is 588 (42 x 14) which have been roughly 15secs long and i'm running at 44.1khz. this has lead to my RAM overloading and pd shutting locking and crashing. I changed the 4 of the channels to mono and got away with it. but pd still used up nearly all of my 2gb of ram. (i've recently bought more) is there anything i can do to save on RAM?? also how can i calculate roughly how much RAM that pd will need per second of audio array/delay line etc.?? and are there any other factors that are RAM draining (exc GUI)?? Thanks in advance, this list has been more than helpful to me in the past but apologies for lack of brevity this time!
