Re: [PD] [PD-announce] Tutorial: Drum pattern editing in Pd using the rj library
Hallo, Rich E hat gesagt: // Rich E wrote: Ah nice, especially for throwing that together live. Thanks for the tutorial! Not to be too much of a critic on a good tutorial, but... it is quite static though, for the flexibility of pd, don't you think? Limiting all the rhythms to 32nd notes. Frank, I would love to see your approach to creating a more 'dynamic' drum sequencer. I have tried a couple times now and my current one got too complicated quite fast. Yet, I see it as the main benefit for using pd for sequencing over other midi sequencers - there is no limit for beat segmentations. The g_pattern32 object was designed with traditional pop/rock/dance/house/hihop/whatever music in mind. (Btw. the latest version added to the RjDj svn now includes a tiny bit of keyboard support: press t for toggling a step during the first second after selecting it.) But in the end it's just a little sugar coating for a Pd array hopefully making editing arrays graphically a bit less painful but still fast. The table itself can be used as source material for other tasks as well, e.g. as a probability table etc. It would be possible to make a variation of the object where you can resize the array dynamically, use a number box to select steps to edit etc., but as you have seen yourself: It becomes complicated quite fast, which may be a sign that there is no good general approach to editing free form table data and that it may be better to do that in external software like a midi file editor or a spreadsheet. Or that editing it is wrong altogether and instead some algorithmic procedure should be used ...

I wish there was any help or list about ALL the objects availables... ah, and i wish there was a list of ALL people on the world... you can get a list of pretty _all_ Pd-vanilla objects by right-clicking on an empty canvas and selecting help. however, Pd is a dynamic growing system. even while projects like Pd-extended try to catch a good number of portable and working objects available in the wild, it has no real control over the actual objects. if devA decides to add [aobject] it will just show up in the next Pd-extended release without anybody in charge of Pd-extended noticing (this is a good thing); likewise if devB removed [bobject], it will just be gone with anybody noticing it. this makes it very hard to compile a list of all objects in Pd-extended manually (though there are such projects like the one mentioned by derek or pdpedia) one could generate a list of these objects automatically, but usually this wouldn't help you su much (imagine you knew that there exists an object named [morzelpronk]; but what would it do?) because Pd shows only the most commons on the Help section. luckily [*~] is a very common object, so you could have know about it :-) mfgasd.r IOhannes smime.p7s Description: S/MIME Cryptographic Signature ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
[PD] encoding tif sequence (GEM pix_write) on linux
Hi, I tried different solution to create movies from Gem generated tif sequences. The simplest way i found is based on use of the transcode command line program.

ffmpeg* probably supports tif directly, maybe it'd be quicker...

Re: [PD] encoder for gem question
I recommend downloading FFDShow, the FFMPEG codecs for DirectShow, and testing with that. The lightest CPU load will probably be the Motion or Photo JPEG codec or DV.

I could not compile fluid ~. pd_darwin with the sources that I asked. You know how I can to compile fluid for leopard-intel? Where can I get sources for intel? I already tried with fluidsynth but not work for me, and apparently fluidsynth compile the external only for linux. I am desperate, because in all my musical works I use ~ fluid and now that I changed to Intel I dont´have it I need this external a lot please help me!!!

Re: [PD] PTP/libgphoto in PD?
Hey all, I have a draft in SVN under bbogart. I've so far just used it to control cameras and save files on the host computer, not upload files. What is your friend hoping to do with it? In my last installation I realized I need to change the interface a bit, using a commport like open and close between control messages. So the next changes I make will not be patch compatible with what is currently in SVN. Please do let me know your thoughts. .b.
