I love the patch cords. Dunno how I feel about the shadows, though...

RE: [PD] pd-gui wishlist
by mark 26 Apr '02

26 Apr '02

I know its boring but the main thing I would like from the GUI is for it to look nicer - Jmax despite not doing half the things I want it to looks fantastic and is nice to use. When you are using a tool a lot - how it looks IS important. cheers mark -----Original Message----- From: Josh Steiner [mailto:joschi@eds.org] Sent: 22 April 2002 22:41 To: Pure Data Subject: Re: [PD] pd-gui wishlist I forgot to say, I'd love it if people would share their gui improvment brainstorms in this thread. I've been tinkering around in the pd tcl code and would like to find some way to help while learning. the more ideas i hear, the more likely i will find one that i can implement. ________________________________________________________________ Josh ..

linked-slider logic
by David McCallum 25 Apr '02

25 Apr '02

I'm writing a really simple delay abstraction with separate delay times for the left and right channels. But I've included a toggle to control whether the left and right sliders are linked, so that they are both set to the same value. The thing is, I can only really simply implement this when one of the sliders is the controller, and the other one the slave, otherwise I get a loop going if I let them control each other. Has anyone implemented this kind of logic into their patches? I'm sure it's pretty simple. I can sort of think of detecting which slider has been moved and then using some spigots to route the information from the moved slider to the other one... But I'm having trouble visualising exactly how I'd go about this, especially if I want the user to be able to drag either of the sliders. Any help would be super appreciated. . . David McCallum .

Re: [PD] pd and serial object
by Bob Falesch 25 Apr '02

25 Apr '02

[serial i/o under win32] -- even when using a separate worker-thread, i've usually wound up using non-blocking modes (generally "overlapped i/o", rarely "i/o completion ports"). this is with sockets and pipes too. asking a thread to terminate when it's got a blocking call can be messy, and polling-with-timeouts can be inefficient (horribly so if on the primary thread). without studying the pd serial issue further, i don't have any specific recommendations, but bear in mind that OVERLAPPED (asynchronous) is needed to enable more than one operation to be performed with the same handle, like a simultaneous read and write. also the ReadFile() and WriteFile() functions need a _lpOverlapped_ parameter the points to a OVERLAPPED structure (this maintains buffer-position pointers that would otherwise be done by the system under the covers). cheers, ______________________ | b o b f a l e s c h | www.zeggz.com/raf/

PD gui patches
by Joseph A. Sarlo 25 Apr '02

25 Apr '02

Well, I've been extra bored at work lately so I've been messing around with the PD gui. I cleaned up the colored signal patch cord stuff so cut/paste works properly and the inlets/outlets appear "on top of" the patch cord. I also added patch cord highlighting for delete, so that when you mouse over a patch cord and the delete 'X' appears, the patch cord you're above turns blue. Also, I added drop shadows to objects, messages, and atoms. Unfortunately it slows down editing when you're dragging a large group of objects, but it sure looks pretty! You can get the patches at: http://mambo.peabody.jhu.edu/~jsarlo/pd/ If I have time later tonight I'll see about posting a compiled Windows binary. Joe -- ______________________________ | | Joseph A.

Made with PD
by mark 25 Apr '02

25 Apr '02

I have a new track available - http://www.junklight.com/april02/taikonaut.mp3 Made almost entirely in PD... (using the vst~ to run Attack, granular synthesis and sound file playback) Its essentially an experiment in IDM type sound that came from testing a drum machine I am building in PD that is designed to do polyrhythms and to let different length sequences play against each other. The other sound source is the BBC :-) cheers mark

wahwah patch
by Yves Degoyon 25 Apr '02

25 Apr '02

hi, i've been trying to make a patch which produces a wah-wah effect, as the theory says, it moves a peak frequency in a bandpass filter, but i'm not too satisfied with the result. my questions are : a/ did someone already did this ( in a better way ) ?? b/ if not, how could my patch be improved ?? ( i guess i must add a saturation of some sort ) c/ anyone modelized saturation ? ?? cheers, yves. #N canvas 112 118 681 488 10; #X obj 143 98 osc~ 250; #X obj 112 225 rs-pwah; #X obj 208 344 dac~; #X msg 169 175 bang; #X connect 0 0 1 0; #X connect 1 0 2 0; #X connect 1 0 2 1; #X connect 3 0 1 1; #N canvas 104 28 681 488 10; #X obj 204 235 hip~; #X obj 220 275 lop~; #X floatatom 269 311 5 0 0; #X obj 359 216 + 0; #X obj 307 216 - 0; #X obj 456 158 / 2; #X floatatom 510 157 5 0 0; #X floatatom 336 179 10 0 0; #X obj 517 80 loadbang; #X text 506 187 Bandwidth; #X text 227 175 Peak frequency; #X msg 515 116 1; #X obj 331 70 f; #X obj 285 70 + 1; #X obj 208 344 outlet~; #X floatatom 515 35 5 0 0; #X text 569 36 higher freq; #X floatatom 516 6 5 0 0; #X text 566 9 lower freq; #X obj 262 12 loadbang; #X msg 286 46 400; #X obj 86 253 inlet~; #X obj 336 11 inlet; #X obj 229 312 *~ 1; #X obj 331 40 metro 1; #X obj 428 68 < 200; #X obj 441 99 route 1; #X obj 372 111 > 1600; #X obj 371 136 route 1; #X obj 140 87 * -1; #X floatatom 137 59 5 0 0; #X text 95 58 Step; #X obj 134 169 f; #X obj 173 168 f; #X msg 172 139 bang; #X msg 134 139 bang; #X connect 0 0 1 0; #X connect 1 0 23 0; #X connect 2 0 23 1; #X connect 3 0 1 1; #X connect 4 0 0 1; #X connect 5 0 3 1; #X connect 5 0 4 1; #X connect 6 0 5 0; #X connect 7 0 3 0; #X connect 7 0 4 0; #X connect 8 0 11 0; #X connect 11 0 6 0; #X connect 12 0 13 0; #X connect 12 0 7 0; #X connect 12 0 25 0; #X connect 12 0 27 0; #X connect 13 0 12 1; #X connect 15 0 27 1; #X connect 17 0 25 1; #X connect 19 0 20 0; #X connect 20 0 12 0; #X connect 21 0 0 0; #X connect 22 0 24 0; #X connect 23 0 14 0; #X connect 24 0 12 0; #X connect 25 0 26 0; #X connect 26 0 34 0; #X connect 27 0 28 0; #X connect 28 0 35 0; #X connect 29 0 32 1; #X connect 30 0 29 0; #X connect 30 0 33 1; #X connect 32 0 13 1; #X connect 33 0 13 1; #X connect 34 0 33 0; #X connect 35 0 32 0;
