auto-adding MIDI devices
by Hans-Christoph Steiner 26 Mar '12

26 Mar '12

I was just thinking, currently Pd can get a list of the active MIDI devices, on Windows and Mac OS X at least. Would there be any problem if Pd just automatically added those and enabled them if there weren't any preferences saved? So if someone has setup their MIDI devices, then they would not be touched. But if the MIDI device setup was just device, it would just add the MIDI devices found by sys_get_midi_devs() in sequential order. .hc ---------------------------------------------------------------------------- Programs should be written for people to read, and only incidentally for machines to execute. - from Structure and Interpretation of Computer Programs

Extracting delimeters in OSC ??
by Фывапр Олджэвич 26 Mar '12

26 Mar '12

Seems it is still a problem. We can't unpack list from VVVV, sent to one OSC channel of UDPrecieve... I think it is because of the delimiter problem... it is recognised by PD as a list element.. Any help how to extract one particular element form list ? So we have a list of 100 elements, and every second of which is SPACE or COMA .. e.g. : 29,51,34,11,123, How can I extract COMAs from this to get just pd's appropriate list ? Any object to find and extract delimiter ? thanks

Re: [PD] Extracting delimeters in OSC ??

Hello! if you use PD_ext, have a look in the jasch_lib: there is an external called strtok that helps you getting rid of characters. although i would rather suggest changing the way you pack the OSC messages in vvvv, that in the end you would end up with messages ála: /A/B/ 29 /A/C/ 51 ... peter -----Ursprüngliche Nachricht----- Von: "Фывапр Олджэвич" <tofuckof(a)inbox.ru> Gesendet: 26.03.2012 16:00:00 An: PD-list <pd-list(a)iem.at> Betreff: [PD] Extracting delimeters in OSC ??

pix_artoolkit + pix_colorclassify > pd.linux
by xä 25 Mar '12

25 Mar '12

Hi list, im in a workshop with not so many time ...so im wondering if somebody has 2 .pd_linux (pix_artoolkit + pix_colorclassify)...(that we'd need for a demo in progress. after tried to install them i have several errors compiling them but not the time to solve it. so .pd_linux would be nice right now I ve been searching for those precompileds on the net but dont find them....any url suggested that i missed? The purpose is that we'd need to solve an engine that detects several colours at the same time from a cam. The point is that AFAIK pix_artoolkit or pix_colorclassify should be useful for this purpose but maybe another solution (?) another not-tricky-and-direct-solutions will be welcome :) thanx xa 2012/3/24 Фывапр Олджэвич <tofuckof(a)inbox.ru>: > I used to send via MIDI just one note stoccato but repeated in a very high > speed from my PD-sequencer to the old KAWAI PHM-synth module.. > > at the same time I sent Programm-change messages with the same speed to the > device ..

Hello PD List
by speed wolf 25 Mar '12

25 Mar '12

Hi, This is my first post here. I'm very new to PD and am looking for some good beginners tutorials. I'm not a stranger to coding having been a web developer for a decade or so but I'm not used to visual programming environments and am finding it a little counter intuitive. Usually I do generative stuff with DVDs but I'm moving into a much more interactive space at the moment and need to learn some new skills so if anyone could offer a few pointers I'd be extremely grateful. You can look at some of my stuff here if the fancy takes you - http://www.petehaughie.com/

cool ways to use pd in keyboard rig
by Andrew Faraday 24 Mar '12

24 Mar '12

Hey Guys Can we talk concept for a bit? I'm building a performance rig with two keyboard synths, kaossilator, feedback mixer and a home-made instrument (a stripped down hard-drive with a guitar lead soldered to the motor, nice little, imprecise, instrument). I'm looking at using pure data on a laptop with my m-audio axiom controller with the rest of the rig. Basically I'm looking for something cool, experimental but not too out-there to do in a pd patch to compliment this synth-heavy setup. Not sticking to any particular style, either, just seeing what I come up with. Basically, feel free to throw ideas at me Cheers Andrew
