glitch when using switch~ to apply fx
by patrick 05 Jan '07

05 Jan '07

hi, here's a patch that use switch~ to turn off/on an effect. using switch~ will save some cpu when the effect is turn off right? so that is good, but the thing is i have a glitch when switching... is there a way to avoid this? or maybe there's a better way for this kind of setup in -> fx1and/or fx2 and/or fx3 -> out. i will add a dry/wet option to the fx part. pat

pidip and libdpstk
by Pall Thayer 05 Jan '07

05 Jan '07

Hi list, I'm trying to get pidip workin on a Linux box. I installed pd- extended and have been moving through the dependencies for pidip, one at a time, without problems. But now it wants libdpstk and from what I can gather, it's obsolete and I can't find it anywhere. Anyone know where I can get it? Pall -- Pall Thayer palli(a)pallit.lhi.is http://www.this.is/pallit

IEM version of pdogg
by Hans-Christoph Steiner 05 Jan '07

http://www.elec.qmul.ac.uk/dafx03/proceedings/pdfs/dafx66.pdf It this paper, there is talk of an IEM version of the ogg streaming objects that allow for multichannel streaming. It doesn't look like that code is in the CVS version. Is it available somewhere? .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

makefilename query
by timon 05 Jan '07

05 Jan '07

Hi, I need to get the index (or decimal) value of a character. I know I can get the reversed result through [makefilename %c]. [Ascseq] does it but not with an extended character set. So Im wondering if there is a [makefilename %?] that can achieve that. Thanks, Timon.

text files, character mapping, PD & GEM Text
by timon 05 Jan '07

05 Jan '07

Hi, just thought Id share this. Ive been faffing around some time to get the correct character mapping from a loaded text file into GEM text objects. Im on OSX so this might not be applicable on other platforms. Anyway, a UTF-8 formatted text file will give the right character mapping into pd (even japaneese characters). Sadly they wont map correctly into GEM text objects, only the basic ascii. A Windows Latin 1 (1252) formatted text file (with its limited 256 characters) gives the right character map into PD and GEM text objects. What I found particularly confusing is that special characters such as Ü or Æ from the UTF-8 format file displayed correctly in PD, but would not map correctly in GEM. The same characters, Ü and Æ, from the Windows Latin 1 format file showed the same characters in PD while mapping them correctly in GEM. So, in case anyone else have been stuck with this. Timon.

Problems stopping strange signal path
by Vreahli the Audio Bandit 05 Jan '07

05 Jan '07

Hiya - I'm having some issues with this patch I've been working on. I just baked up some fancy bit crushing using expr~ and I'd like to turn it off. On the linear version on the right it stops just fine, however on the left the noise continues to flow out. In the patch I've got an array that should be showing the output when you bang the metro - but it doesn't show any output until I multiply the problematic signal path with 1 instead of 0. I'd be totally in anyone's debt if they could crack open this patch and figure out what I broke. :) Thanks! #N canvas 0 0 889 677 10; #X obj 154 104 soundfiler; #X obj 153 62 openpanel; #X obj 153 29 bng 15 250 50 0 empty empty empty 17 7 0 10 -262144 -1 -1; #N canvas 0 0 450 300 (subpatch) 0; #X array array1 173440 float 2; #X coords 0 1 173440 -1 200 140 1; #X restore 314 12 graph; #X msg 153 84 read -resize \$1 array1; #X obj 45 146 bng 15 250 50 0 empty empty empty 17 7 0 10 -262144 -1 -1; #X obj 41 536 dac~; #X obj 46 191 tabplay~ array1; #X obj 452 375 hsl 100 15 2 100 1 1 empty empty empty -2 -8 0 10 -262144 -1 -1 7200 1; #X obj 44 49 bng 15 250 50 0 empty empty empty 17 7 0 10 -262144 -1 -1; #X obj 45 419 /~; #N canvas 0 0 450 300 (subpatch) 0; #X array array3 100 float 3; #A 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0; #X coords 0 1 99 -1 200 140 1; #X restore 237 473 graph; #X obj 624 438 tabwrite~ array3; #X obj 451 182 metro 10; #X obj 42 90 metro 3920; #X obj 44 275 samphold~; #X obj 153 251 phasor~ 1050; #X obj 156 231 hsl 128 15 220.5 22050 1 1 empty empty empty -2 -8 0 10 -262144 -1 -1 12700 1; #X text 454 358 Bit crunching; #X text 154 218 Sample rate abuse; #X msg 83 62 stop; #X obj 44 320 expr~ pow((int(pow(($v1*$i2) \, 3))) \, -3); #X obj 294 313 expr~ int($v1*$i2); #X text 76 301 Cubic; #X text 314 296 Linear; #X obj 87 539 savepanel; #X obj 87 584 writesf~ 2; #X msg 87 562 open \$1; #X obj 87 518 bng 15 250 50 0 empty empty empty 17 7 0 10 -262144 -1 -1; #X msg 142 562 start; #X msg 182 562 stop; #X obj 295 369 *~; #X floatatom 308 350 5 0 1 0 - - -; #X obj 45 363 *~; #X floatatom 58 342 5 0 1 0 - - -; #X text 71 362 Ye problem lies here!; #X text 218 182 Debug noise; #X obj 177 182 noise~; #X text 525 10 This is a WIP bitcrusher and sample rate reduction unit.

[*] vs [*~]
by Mathieu Bouchard 04 Jan '07

04 Jan '07

I have some newbie questions here... why is it that [*] is only for floats, whereas if you want to multiply two signals one has to use [*~] ? And then why is it that [*~] can multiply a signal by a float, but [*] can't do that? And then why is it that [*~] can't multiply a float by a signal, the signal has to be on the left? Why is it that if I want to divide a float by a signal, then I have to explicitly cast the float to signal (using [sig~]) or use [expr~] ? _ _ __ ___ _____ ________ _____________ _____________________ ... | Mathieu Bouchard - tél:+1.514.383.3801 - http://artengine.ca/matju | Freelance Digital Arts Engineer, Montréal QC Canada
