Digital outputs, Arduino Mega 2560 & Pduino = problems
by Ezequiel Abregú 15 Aug '13

15 Aug '13

Hello: I wanted to ask a question. I'm using a arduino mega 2560 board with pduino (http://at.or.at/hans/pd/objects.html). My problems is... 1) The digital outputs 24 to 36 do not work. 2) digital outputs that work do not respond when I give you a message LOW. For example, [digital 53 0 ( NOT WORK. I was wondering if there is now a solution to the problem. I tried running the example BLINK and all digital outputs works OK. Thanks a lot & Cheers

Cool Video of Miller
by Billy Stiltner 13 Aug '13

13 Aug '13

I dont think we as a group could appreciate the work of Miller enough. Even though his C geniusness has churned out some sort of interface not unlike an object oriented visual c++ object with connectors I mean think about it. make a new pd object itś like saying make a new class that does these functions on this data with a bit of $0 trickery you can even make the classes data private and make multiple instances of the class. Iḿ not sure that it would have been possible to make such a beast using c++.

building Pd vanilla with mingw
by Jonathan Wilkes 12 Aug '13

12 Aug '13

Hello list, Before I go down yet another infinitely deep rabbit hole, has anyone actually compiled a _working_ Pd 0.44 Vanilla using mingw? If so, what did you do other than a) avoiding compiling in a directory that has spaces somewhere in the path (really? in 2013 this is still a problem?) b) ./autogen and make I must be doing something wrong because it's complaining about missing functions relating to pd-watchdog, and if I'm not mistaken pd-watchdog doesn't even run on Windows. Thanks, Jonathan

Benefits of using an external soundcard?
by Mario Mey 12 Aug '13

12 Aug '13

I'm using my integrated soundcard: 00:14.2 Audio device: Advanced Micro Devices [AMD] nee ATI SBx00 Azalia (Intel HDA) (rev 40). I know that Pd is processing on CPU and I don't need more than 2 inputs and 2 outputs channels. So... I "think" that there's no need to buy an external one. Is there any benefit of using one? I know that this USB soundcard is not a very good one... but maybe it's good for my economy. What's your opinion? http://www.encore-usa.com/ar/support/ENMAB-8CM

order of audio connections (BUG???)
by Alexandre Torres Porres 12 Aug '13

12 Aug '13

Hi there, I was making some tests and saw that the order that you make audio connections or create tilde~ objects make a difference, and this affects when we're using [s~] / [r~]. The idea I had is that no matter what was going on, the sends and receives would ALWAYS be in sync with the audio conenction cords, meaning there would be no delay whatsoever. But that's not true, so I suspect this is some sort of a bug that should be noted. check the following patches, they are the same, but one is "ok" (where the audio is cancelled) and the other "not ok" (where it isn't). The only difference is the order that the objects were created and connected. I, for one, would like to live in a Pd world where it'd always be "ok" no matter what... cause if we have these delays, it ends up being really bad, right? what about you people? And is this too hard to "fix"? cheers The patches: * * *"OK"* #N canvas 223 59 450 300 10; #X obj 99 162 -~; #X obj 90 198 dac~; #X obj 242 85 loadbang; #X msg 242 114 \; pd dsp 1; #X obj 114 111 s~ \$0-osc; #X obj 114 133 r~ \$0-osc; #X obj 99 73 osc~ 440; #X connect 0 0 1 0; #X connect 0 0 1 1; #X connect 2 0 3 0; #X connect 5 0 0 1; #X connect 6 0 0 0; #X connect 6 0 4 0; *"NOT OK"* #N canvas 223 59 450 300 10; #X obj 99 73 osc~ 440; #X obj 99 162 -~; #X obj 90 198 dac~; #X obj 242 85 loadbang; #X msg 242 114 \; pd dsp 1; #X obj 114 111 s~ \$0-osc; #X obj 114 133 r~ \$0-osc; #X connect 0 0 1 0; #X connect 0 0 5 0; #X connect 1 0 2 0; #X connect 1 0 2 1; #X connect 3 0 4 0; #X connect 6 0 1 1;

"Programming Sound with Pure Data" Book Review
by Tony Hillerson 12 Aug '13

12 Aug '13

Hello All, I'm currently writing a book for the Pragmatic Programmers (http://pragprog.com) called "Programming Sound with PureData". It's a book that introduces the reader new to designing sound to PureData, and is geared towards iOS and Android app and game developers who want sound in the apps they're making. I'm wondering if anyone is interested in tech reviewing the book. That means reading through the book so far (around 5 chapters) and following the examples and then writing up what you think of things so far. I estimate this would take between 4-8 hours over a few days. This is not an advanced Pd book. Although it covers libpd, it's got more sound design information than "Making Musical Apps", but a lot less than the venerable "Designing Sound". I hope to be able to introduce Pd to a lot of iOS and Android devs who deal with static samples. I also have a chapter on exporting for the web from Pd. The rest covers a lot of synthesis and sound design basics. If you're interested, just shoot me an email and I can get you in touch with my editor. I'd be really excited to have you as a reviewer. If you can't fit the review into your schedule, no problem. I need a few people, so first come first served. Thanks for your time, Tony -- Tony Hillerson

abstraction penalty benchmarks
by Claude Heiland-Allen 10 Aug '13

10 Aug '13

Hi, Today I remembered one performance where I saved an abstraction with many instances, bringing things to a halt. So I benchmarked this scenario and some similar ones - some seem to scale very badly. pure-data.git gcc-4.8.1 GNU/Linux/Debian/Wheezy amd64 64bit Pd-0.45.0 ("test") compiled 17:10:02 Aug 8 2013 m n open dsp save close 3 512 38.503 1.33879 44.26 3.985 4 4096 324.507 10.7379 786.227 150.602 5 32768 2611.92 85.405 79234.2 35853 key description m number of levels of nested abstractions n total number of instances at deepest level open time to load patch dsp time to toggle dsp on then off (1000 runs averaged) save time to save one instance at deepest level close time to close patch all times are in ms, measured with [realtime] rows run sequentially in their own pd instance dsp was off at the start of each test the whole run is in zero logical time cpu frequency scaling was disabled (for real) pd was run with -nogui -nosound -nrt The killer in the bottom right corner: with 8x as many abstractions, it takes 100x as long to save an instance, and 200x as long to close the patch. See attached tarball if you want to try it yourself. Claude -- http://mathr.co.uk

eowave ribbon
by Samuel Burt 10 Aug '13

10 Aug '13

Hey listers, I've been thinking a lot about the Ondes Martenot and wondering what it would be like to use for MIDI-style control. Have any of you used the Eowave Ribbon controller with Pd? How well does the "tactile pad" pressure sensor work? I wish for an envelop controller like the Ondes Martenot has. Has anyone seen controllers like this? http://huebnerie.de/blog/wp-content/uploads/2011/01/om5_touche.jpg Samuel Burt
