Sequencing characters?
by Ronni Montoya 18 Aug '14

18 Aug '14

Hi, i have a string of characters in a message, like this: [ababacbabcdabacdeacbcbacbeab( I need to use this for sequencing, basically i need to read each character each time ( each trigger) and then select and event based on the character. So i have 2 questions: How can i read each character in the message each trigger ? and , Is there is any object like select that work with characters ? for example: [select a b c d e] ? Which approach would you recommend for this? thanks in advance R,

Hi, im running a clean install of Ubuntu 12.04, with Puredata 0.43.0-4 from Ubuntu repos, with a compiled Gem-0.93.3.

deeper csound6~ question
by forrest curo 18 Aug '14

18 Aug '14

I'm concluding that pd runs csound (via [csound6~] ) directly in some way -- and that the instance of csound it's running does have access to the system outside the csound6~ interface: for example, if I put a widget in the .csd file I'm playing, it normally won't get displayed. But If I put it in a widget panel in the file, it does -- not through pd, correct? If I just wanted to use pd to send controls ( via [HID] for example), I'd expect I wouldn't need to run pd at dsp rate, could have the csound instance send audio directly to dac... but putting the -odac flags in the .csd file doesn't seem to do it. [These do work if I run the same file via command line.] Is the audio from [csound6~] trapped within the interface somehow? Or is pd grabbing the dac even when I use 'Audio Settings' to turn 'Input device 1:' off? Is there an easy fix? -- or would I do better to just run the audio back into pd & out via [dac~] as is customary?

#N struct
by Jonathan Wilkes 17 Aug '14

17 Aug '14

Miller, Is it ok to add (potentially) more "#N struct etc." headers to patch files, specifically for templates that are defined in that patch? It looks like that header is currently written for orphan scalars, or for scalars whose template might be defined elsewhere (like in a patch or abstraction which hasn't loaded yet). But I've added some checks in gtemplate_new to prevent [struct] objects from creating when there are circular dependencies and/or undefined array element templates. In those case, having the "#N struct" headers will ensure that the structs will be able to create when the patch is reloaded. This should prevent the user from crashing Pd when manually creating [struct] objects, while the "#N struct" stuff will let Pd create all the templates it needs for the patch to load correctly. (Of course someone could still edit a patch file by hand and cause a circular dependency crash or something, but I'm not sure how to prevent that.) That would leave a single reallocation crasher somewhere in template_conformglist. It happens when you have scalar with array elements in it, and you start mucking around with the [struct] args of either the container or the array element template. (I can't reproduce it reliably yet.) -Jonathan

We'll integrate a testing branch into libpd, just haven't gotten to it yet.

[PD-announce] Arduino for Pd'ers tutorial
by Alexandros Drymonitis 15 Aug '14

15 Aug '14

Hi list, I've written a tutorial on the communication between Pd and Arduino, aimed at Pd users who want to program Arduino without using the Firmata firmware. You can get it here http://drymonitis.me/code/ (look for the specific link). The .zip file contains the tutorial .pdf, all Arduino sketches, Pd patches, as well as Fritzing files of the circuits. The tutorial is split in ten projects which are the following: 1 - digital output 2 - digital input 3 - analog input 4 - analog output 5 - analog and digital output 6 - more than one analog inputs 7 - servo motors 8 - analog and digital input 9 - multiplexing 10a - output shift registers 10b - input shift registers Feedback is welcome : ) _______________________________________________ Pd-announce mailing list Pd-announce(a)lists.iem.at http://lists.puredata.info/listinfo/pd-announce

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!
