searchpath inside patch
by Achim Bornhoeft 18 Jan '16

18 Jan '16

Is there a possibility to put a statement (relative pathname) inside a patch where to look for additional abstractions, for example to search for abstractions inside a subfolder "abs" which is in the same directory than the patch itself. Thanks for help, Achim

acid
by Chris McCormick 14 Aug '14

14 Aug '14

Hi, Another question in a very general vein. I asked this on the Csound list a while back (when i was using csound) with good results. I'm trying to produce an acidy type sound (eg 303) and having trouble as my current saw-tooth-through-a-vcf just sounds pretty wimpy. Any ideas on how to fatten it up a bit? I'm not looking for a perfect reproduction of the 303 sound, just a nice acid sound. Hints? Tips? Is there some place where people post interesting Pd patches they've created for others to download at try out? Should there be? Regards, Chris. ______________________________________________________ Chris McCormick - Systems Developer - PerthWeb Pty Ltd Internet Solutions for your business!

window-switching on OSX?
by Damian Stewart 15 Jan '11

15 Jan '11

How do I switch between open windows on OSX using the keyboard? On PC I used to be able to Ctrl-Tab. The OSX equivalent of that is Apple-`, but it doesn't do anything; Apple-Tab on OSX switches applications, which doesn't help either. cheers D -- Damian Stewart +64 27 305 4107 f r e y live music with machines http://www.frey.co.nz http://www.myspace.com/freyed

Re: [PD] PD] request assistance with crackles and pops in VFOs driven, by modulating accelerometer signals
by Collin Oldham 03 Jul '10

03 Jul '10

I think you are getting those crackles from the atoms (number boxes) that are trying to redraw every time they get a new number from the accelerometers. (which is probably pretty often!) That would explain why it only happens you are using the sensors, and why your very sensible solutions didn't work. Just a hunch! I'd try hiding it all in a sub patch, and if that works, you could use something like [speedlim] (from cyclone?) to limit the refresh rate on the atoms. Collin http://homepage.mac.com/coldham/klang

'apple' lib for controlling hardware and getting sensor data
by Hans-Christoph Steiner 15 Nov '09

15 Nov '09

Hey, I just finished of a quick library of functions for controlling some of the hardware features on Apple computers when running under Mac OS X. So far, I have been able to control the screen brightness; control the keyboard backlight brightness and fade time; get data from the "sudden motion sensor" or built-in accelerometer; and get data from the built-in light sensors. It's included in the nightly builds as the 'apple' library, check 5.reference -> apple in the Help Browser for help patches. Also, this should be pretty easy to do for other computers. For example, the Thinkpad features are pretty well documented under Windows and GNU/Linux: http://www.almaden.ibm.com/cs/people/marksmith/tpaps.html http://www-128.ibm.com/developerworks/linux/library/l-knockage.html http://www.almaden.ibm.com/cs/people/marksmith/sdl.html http://www.gnome.org/~fherrera/gtollina.c Or for Apple hardware, there is pbbuttonsd: http://pbbuttons.berlios.de/ .hc ------------------------------------------------------------------------ ---- ¡El pueblo unido jamás será vencido!

jack_transport improvements
by Jacob Lee 27 May '09

27 May '09

I've added some code to the jack_transport external (tb/jack_transport/ in pd-extended) to show the current bar/beat (and also bpm and tempo) in real time. Messages are only sent out when pd is computing audio, and also no more than once per beat (to avoid floods of messages). I'm not outputting all the available information from the jack transport -- e.g. the current tick within the beat -- either because it updates too quickly or because it's just not useful to me, but it would be trivial to add those. The motivation here is that I'm using klick -- http://das.nasophon.de/klick/ -- as the jack transport master (mainly to control sooperlooper), and now it is possible to trigger events within pd at particular beats or bar numbers. The code is available at http://artdent.homelinux.net/svn/jack_transport~/ . The makefile should be suitable for building jack_transport~ from inside a directory that is sibling to the existing jack_transport. I've only tested it on Linux, but it should work anywhere jack_transport does. I hope this external is useful to others. Suggestions for improvements are of course welcome. -- Jacob Lee artdent(a)gmail.com

Hi, I started to learn to use Blender for controlling it with puredata with OSC protocol, I would have been glad to use gamelogic sockets instead but it's poorly documented and OSC seems more useful in huge project implementations Welcome to any kind of comment instructions are into blend file

Thanks, Martin! Out of curiosity - what compiler did you use? I've never compiled externals on win xp but would like to learn how. Is it possible to use the free version of MS Developer Studio? Other alternatives? I'd like to try to make a stereo version of moogladder~ and also try tanh optimizations to reduce the cpu load. /Anton ------------------------------ Message: 4 Date: Wed, 27 Aug 2008 09:18:38 +0200 From: " Anton H?rnquist " <anton.hornquist(a)gmail.com> Subject: [PD] Csound opcode Moogladder to Pd To: pd-list(a)iem.at Message-ID: <58a0928c0808270018w1fed3676tba57e9a7e741fbdf(a)mail.gmail.com> Content-Type: text/plain; charset=ISO-8859-1 > I now made a version where cutoff and resonance are signals.

I think the Csound-version has cutoff restricted to 0...1, which is 0...11050 in hertz.

I think the Csound-version has cutoff > restricted to 0...1, which is 0...11050 in hertz. Only resonance is restricted to 0 and 1. It is in the pd version as well. I made some tests now and it seems it's not the cutoff frequency alone that makes the filter run wild. With resonance set to 0 a cutoff of 96kHz when running at SR = 48kHz doesn't go wild. But set resonance to 0.1 and it runs away. So in the end I'd say, just be careful and if in doubt [clip~] your input values. Another issue may be denormalization, so some PD_BIG_OR_SMALL checks could be useful.
