Re: [PD] tutorial on struct/template usage?
by Nicola Bernardini 27 Apr '08

27 Apr '08

Dear all, thanks for all your replies - and sorry for not having thank you before: for some reason I am not receiving mail from this list, so I had to go in the archives and find out that Miller and Frank had actually replied to me (thanks!). Miller, the 4.data.structures page is not in my distro - I am currently using the vanilla 0.40.2-2 version which comes with Ubuntu Hardy, but it's not in there :( I'll try to find out why - perhaps there's something wrong with the package. Frank, thank you very much - I will study the tutorials, I guess that's really what I need. nicb -- Nicola Bernardini e-mail: nic.bern(a)tiscali.it http://www.nicolabernardini.info GPG fingerprint = 6AE6 AF21 E160 D9B3 396E EBAC 906C CFAE 4D65 D910 Neither MS-Word nor MS-PowerPoint attachments please. > Fri Apr 25 16:52:11 CEST 2008 > > They're obscure by design (I'm trying to think of a more straightforward > design but can't).

polymatrix...patchbay for audio and anything
by Luigi Rensinghoff 27 Apr '08

27 Apr '08

Hi List I just build a little memento-ified matrix for 24 ins and 24 outs (only one single outlet allowed per inlet) which i need for patching parameters between wii-Data-and synth- control.. it works for bangs and numberstreams so far well the best thing would be to use the same matrix for audioconnections as well. It might sound a bit absurd, but what i am looking for is something like route signal float - well of course i know i have to build an abstraction for that myself.... Any Ideas which path to follow with that ?? How are your solutions for building a flexible patchbay ot that kind ?? Thanks Luigi P.S. i have attached the patchbay as it is for now.. If you have any suggestions or ideas, improvements or ways to do that much easier and more efficient ia m very thankful >---------------------------------------< Luigi Rensinghoff luigi.rensinghoff(a)freenet.de skype:gigischinke ichat:gigicarlo

I gotta point out that my intention was not to be rude, but rather to point out that if, and i may very well be wrong, z~ implementations need dynamic patching which is an unsupported feature then its not a robust solution hence not the best to add to a printed book.

Re: [PD] Cyclone in vanilla?

> Date: Tue, 22 Apr 2008 16:02:37 +0100 > From: Andy Farnell <padawan12(a)obiwannabe.co.uk> > Subject: Re: [PD] Cyclone in vanilla? > To: pd-list(a)iem.at ================= > Right now my 'missing' list includes [z~], [abs~], [ln~], [log~], > [pow~], [tanh~], [cosh~] One might put [atan~] and [atan2~] on this list as well. [ln~] and [log~] probably ought instead to be [log~] and [log10~], respectively. Actually, for those of us who insist on vanilla and do everything with expr/expr~/fexpr~ or abstractions, is it possible to implement [z~] in fexpr~ for a delay larger than its vector size? You could do it with an abstraction using [delwrite~] and [delread~], setting the [block~] to 1, and then set the delay as a ratio to the [samplerate~] -- the difficulty in making it work correctly here is setting the size of the [delwrite~] efficiently (this could maybe be done with a loadbang routine that would send a message to a subpatch in the abstraction instance to add and connect a delwrite~ with the proper delay allocation...). In pedagogical situations such an example might also be useful for gently introducing the block/vector structure of PD that you would need anyway for proper delay/feedback examples as well as FFT (and possibly for sending messages to subpatches), but I'm pretty sure it's not the most efficient model available. On a similar note, is it possible to recreate things like [zexy/noish~] or [zexy/noisi~] in vanilla PD as an abstraction? It would be great to have these for building pinkish noise or random control of other audio parameters, and these seem fairly primitive to any serious synthesis engine. Thanks, Matt

contextual pdpedia menu link
by Hans-Christoph Steiner 27 Apr '08

27 Apr '08

Hey all, I just checked in code to make the Pdpedia link in the Help menu try to find the object name if you are looking at a help patch. If the help patch is the topmost window, it'll use that object name when it opens the pdpedia and take you directly to that page. Should be in tomorrow's builds. This got me thinking that there should be a Pdpedia link in the popup menu that currently has Help, Properties, and Open in it... .hc ------------------------------------------------------------------------ ---- "[W]e have invented the technology to eliminate scarcity, but we are deliberately throwing it away to benefit those who profit from scarcity." -John Gilmore

pd on multi touch
by Ben Carney 27 Apr '08

Hello there all, Is there any work being done on getting pd to tun on a multi ouch device such as the ipod touch or iphone? I think this would be an amazing experience, connecting patch chords with a fingertip or stylus best, -- Ben C.
