applying perlin value to each iterated geo
by topo bot 06 Sep '13

06 Sep '13

Hi, im generating structures iterating geos in gem and was wondering how can i apply an value from a perlin noise to each iterated structure. In processing i can do this in this way: for(int i = 0 ; i < 20 ; i ++){ float perlin = noise( i * noiseScale, j * noiseScale); pushMatrix(); translate(0 + (i * 20) , 0); translate( 0, 0 , perlin * 30 ); rotateX( perlin ); rotateY( perlin ); box(perlin * 20 + 20); popMatrix(); } How can i do the same with Gem? I been trying in the following way but its not working, any idea? http://www.freeimagehosting.net/newuploads/2rf7o.png

Sinesum, cosinesum and cubic interpolation's guard points
by Alexandros Drymonitis 05 Sep '13

05 Sep '13

When you send this message [sinesum 512 1( to a table Pd will automatically add one index to the beginning of the table and two indices to its end, and you end up with a table of 515 indices. The three additional indices are the guard points for the cubic interpolation, right? So the first index should be a copy of the last element (here, index 0 a copy of index 512), and the last two indices should be copies of the first two elements (here, indices 513 and 514 copies of indices 1 and 2 respectively). Am I getting it right up to here? Well, with the message [cosinesum 512 0 1( this is indeed true; these are the values I get: index 512 = 0.999925 index 0 = 0.999925 index 1 = 1 index 513 = 1 index 2 = 0.999925 index 514 = 0.999925 Well, the second and the last elements have the same value anyway (index 2 and 512), which makes sense as it's a cosine. But if I send [sinesum 512 1( I'm getting these results: index 512 = -0.0122768 index 0 = -0.0122715 index 1 = 0 index 513 = -5.30718e-06 index 2 = 0.0122715 index 514 = 0.0122662 OK, index 0 is the negative of index 2, which can again make sense as it's a sine (supposing that index 0 is a copy of the table's last element), but index 512 doesn't have that value, why? And why do indices 1 and 513 have different values too?

netiquette (and the phenomenology of learning Pd)
by Joe Deken 05 Sep '13

05 Sep '13

If you are interested about "how people learn Pd" it is informative to peruse the video of Miller's introductory course for undergraduates at UCSD, possibly also the written transcript of the course and all the patches which Miller developed and used in presenting his lectures * http://pd-la.info/pd-media/miller-puckette-mus171-videos/ * http://newblankets.org/MUS171_supplements/MUS171_objects_used.pdf * http://newblankets.org/Miller/MUS_171_patches.zip Apropos the thread of the "subject:" line here -- One thing that struck me was the repeated number of times that the question of scaling appears Miller's lectures, and how long it takes (at least for a portion of the audience) until the algebra/mechanics of the scaling formula become at all familiar, or feel "natural" to these students, if ever. It seems to me that many people have been mis-educated in mathematics, and have an uphill battle to incorporate any formula into their thinking -- even if the formula has only a few steps and just a few variables involved. To watch Miller's lectures and know/appreciate this fact about "simple formulas" seems worthwhile knowledge about Puredata and about math/science education in general.

A giant step sideways for Pd on Android
by Chris McCormick 04 Sep '13

04 Sep '13

Hey all, Just got MIDI input working in PdDroidParty thanks to Peter Brinkmann's new libpd midi glue code. This means you can plug a MIDI controller or keyboard into your Android tablet/phone using the OTG cable, and use it to control Pd on the device. Which means yr gigging setup just shrank to pocket size. Almost certainly bugs. Have at it! http://droidparty.net/ Now I must sleep. Cheers, Chris. PS after you load a patch it's under a menu option. PPS crashes phones/tablets that don't do USB in (< Android 2.3.4 I think). PPS I recently found a really good 7" tablet from Shenzen for $US 88 so we are getting down to Raspberry Pi kinds of prices. Email me if you want the link. -- http://mccormick.cx/

Finally. I was wondering when they'd start supporting MIDI on Android. Now if they could only get the latency to a reasonable level ... On a related note, I will be putting PdParty on iOS out for testing today or tomorrow (depending on 1 last issue to fix). That makes 2 mobile OS's for pockatable pd gigging! iPad + CCK + powered usb hub = midi in/out. Also, network midi over Wifi. Sorry it's taken so long since my first tester announcement at the beginning of the summer. Let's just say what I thought would take 1 week ended up at 4+ in the midst of other goings on. In any case I have some gigs coming up, so gotta get going! Email me if you want to be added to the testers.

Pd <-> Radium
by Kjetil Matheussen 03 Sep '13

03 Sep '13

Slightly inspired by Max for Ableton live, I've added Pd for Radium (Radium homepage: http://www.notam02.no/~kjetism/radium/) Screenshot: http://folk.uio.no/ksvalast/radiumpd.png Video: http://folk.uio.no/ksvalast/radium_pd.ogv It's basically got the same features as Max for Ableton, but I haven't implemented a modular note control system in Radium yet, so you can't, for instance, make an arpeggiator in Pd that controls other instruments. I will implement a modular note control system now though, because of Pd. But at least it's possible to use Pd to make sound effects and soft synths. It's a bit rough yet, so I haven't released anything. You must build Radium from source to get it, for now. It probably also only works on Linux. I haven't tried to compile on Windows or Osx yet. To access pd, I have used libpd, but upgraded it to support several instances, gui, and pd-extended: https://github.com/kmatheussen/libpd

If there is such a tool, I'd wrap it up into a QuickLook plugin on OSX so you could hit the spacebar in Finder and it would render a preview of the patch ...
