Espeak external compilation/loading errors on Linux
by Peter P. 15 Mar '21

15 Mar '21

Hi list, trying to compile and load the espeak external from https://github.com/kronihias/espeak on Debian/GNU Linux. Have the apt packages espeak libespeak-dev installed and the makefile modifiet to point to PDROOT=/usr/include/pd Running 'make' yields an error: cc -export-dynamic -shared -lc -lm -lespeak -DPD -O2 -funroll-loops -fomit-frame-pointer -fPIC -Wall -W -Wshadow -Wstrict-prototypes -Werror -Wno-unused -Wno-parentheses -Wno-switch -I/usr/include/pd/src -o espeak.pd_linux espeak.c espeak.c: In function ‘espeak_setup’: espeak.c:406:6: error: cast between incompatible function types from ‘void * (*)(t_symbol *)’ {aka ‘void * (*)(struct _symbol *)’} to ‘void * (*)(void)’ [-Werror=cast-function-type] 406 | (t_newmethod)espeak_new, // newmethod | ^ cc1: all warnings being treated as errors make[1]: *** [Makefile:79: espeak.pd_linux] Error 1 make[1]: Leaving directory '/tmp/espeak-master' make: *** [Makefile:46: auto] Error 2 which I can circumnavigate disabling the -Werror flag in the makefile. Compilation somewhat succeeds then, posting: espeak.c: In function ‘espeak_setup’: espeak.c:406:6: warning: cast between incompatible function types from ‘void * (*)(t_symbol *)’ {aka ‘void * (*)(struct _symbol *)’} to ‘void * (*)(void)’ [-Wcast-function-type] 406 | (t_newmethod)espeak_new, // newmethod | ^ Loading the external in Pd then throws: ./espeak.pd_linux: ./espeak.pd_linux: undefined symbol: espeak_SetParameter espeak: can't load library Can anyone point me into a good direction what to try next here? Anyone having had success on OS X with this external so far? appreciated, as always, yours, P

How can I send numer 0-255 to an ardino?
by Ingo 15 Mar '21

15 Mar '21

Hi there, I'd like to send integers 0-255 to an Arduino with comport. For text I use [asqseq] to convert it to the ascii numbers that the Arduino uses. However, I don't know how to send plain integers that come in as the same numbers on the Arduino. Thanks! Ingo

OT: Very Old MIDI Keyboard Big Sur
by mitchell turner 14 Mar '21

14 Mar '21

I know this is way off topic, but I’m hopeful one of you was in a similar situation and has a solution. I run a mac lab for my music program. We are getting new iMacs with Big Sur (11.2). I have several (very old) M-Audio MIDI keyboards that I am unable to get running with Big Sur. These Keystation and Radium keyboards are likely 10-15 years old. They are not class compliant and require drivers. Unfortunately, it does not appear M-Audio is going to produce legacy drivers. I’m wondering if anyone has been able to get old MIDI keyboards working on Big Sur? Is there a bridge program, generic driver, etc.? Any help would be appreciated. — Mitch ---------------------------- Mitchell Turner, PhD Professor of Music LaGrange College 601 Broad Street LaGrange, GA 30240 USA Office: 706-880-8015 mturner (_AT_) lagrange (_D0T_) edu class/program links: http://home.lagrange.edu/mturner/ http://home.lagrange.edu/mturner/classes.html http://home.lagrange.edu/mturner/musicdept.htm http://www.facebook.com/lagrangemusic ----------------------------

Re: [PD] Adding up a thicket of oscillators
by Dan Wilcox 14 Mar '21

I'm not quite sure I understand your patching approach enough to debug. If it's at all helpful, I can suggest how I might do this via [clone -n 1] with 72 instances of an abstraction: [inlet] | [route freq gain] | [osc] | [*~ 0.25] <-- perhaps some trim amount as lots of osc are being summer | [*~ ] <--- single osc gain value goes here | [outlet~] The outlets are summed in clone through the output. If you need stereo, it's the same just with two [outlet~]s and some sort of panner. UDP messages would then just need to have the gain values read and applied to the clone instances by their ID, ie. [1 gain 0.25 | [clone 72 -n 1 orc-abs] | [*~ ] <--- master gain | [dac~] <-- or some similar output abstraction Not knowing your networking message layout, I can't say anything else other than "use OSC" as addressing and arguments are relatively easy to work with via: [netreceive -u -b] | [oscparse] | perhaps some routing etc | [clone] > On Mar 14, 2021, at 3:31 AM, pd-list-request(a)lists.iem.at wrote: > > Date: Sun, 14 Mar 2021 03:31:23 +0100 > From: Michael Karr <michael.karr.22(a)gmail.com <mailto:michael.karr.22@gmail.com>> > To: pd-list(a)lists.iem.at <mailto:pd-list@lists.iem.at> > Subject: [PD] Adding up a thicket of oscillators > Message-ID: > <CAOH2gpZ=GUkk4X_kMOku3HeoCc92_xS-GgVTA0iRDWpTTHDQdw(a)mail.gmail.com <mailto:CAOH2gpZ=GUkk4X_kMOku3HeoCc92_xS-GgVTA0iRDWpTTHDQdw@mail.gmail.com>> > Content-Type: text/plain; charset="utf-8" > > Hello! > > I am working on a multichannel sound piece, with 72 oscillators, receiving > data from ffmpeg over udp.

Adding up a thicket of oscillators
by Michael Karr 14 Mar '21

14 Mar '21

Hello! I am working on a multichannel sound piece, with 72 oscillators, receiving data from ffmpeg over udp. Each oscillator stream has its own intensity fluctuations. However, when I try to add the dynamic parts and scale them collectively (using *~ and a very tender slider), I get no output, whereas adding up the raw oscillators does produce audio, minus the individual fluctuations. 1) how do I combine all of these dynamic signals? 2) how can I make else/count start counting the moment information starts flowing through the udp port, and stop again once the feed stops, while keeping the connection active? Kind regards, Michael -- Michael

[PD-announce] ELSE 1.0-0 Beta 37 with Live Electronics Tutorial
by Alexandre Torres Porres 14 Mar '21

14 Mar '21

ELSE 1.0-0 Beta 37 with Live Electronics Tutorial is out and I'm happy to announce its 1st update of the year. I had this idea that when I reached 400 externals that I might be ready to move on past the beta phase. Well, I got 399 now, so I could be close. I got many many breaking changes in this release (the greatest so far from one version to another), so enjoying the fact it's still a beta phase. I also got numerous fixes and improvements in current objects, let me pin point a "freeze" option for ffdelay~/fbdelay~. I got 6 new objects but I'm saving more new ones for the next release that aren't quite ready yet (like a cool preset system). The highlight is [note2pitch] and [pitch2note] that converts from note names to midi pitches and vice versa. I also have a new [del~] object which is pretty much like [delwrite~]/[delread4~] but with some fixes and many extra features, like being able to resize the delay line and freeze it. I made pull requests to add these to vanilla as well, let's see. For a full changelog, downloads, see https://github.com/porres/pd-else/releases/tag/v1.0-beta37 get it also from deken The Live Electronics tutorial is also part of the download and has also been updated, highlights is the revision on the delay lines section, where I also included the new [del~] object and also put an example I was owing on reverse delay lines. We shall also release a new Camomile-ELSE version in the next few days, stay tuned and check it out until it's there ;) https://github.com/emviveros/Camomile-ELSE/releases _______________________________________________ Pd-announce mailing list Pd-announce(a)lists.iem.at https://lists.puredata.info/listinfo/pd-announce

LV2 external for Linux?
by Lorenzo Sutton 12 Mar '21

12 Mar '21

Hi all, Is there any external which can host LV2 plugins, similarly to how [plugin~] does LADSPA? I think the answer is 'no' as I didn't seem to find any references apart from a couple of 12 year old pages on puredata.info - but I guess it's always a good idea to check on the ML as well :-) Thanks Lorenzo

Re: [PD] declare: stdlib vs lib
by Dan Wilcox 12 Mar '21

12 Mar '21

At some point I think I added checking stdpaths *last* in the list for -lib for convenience and to move away for everyone needing to use -stdpath, but I just used what was there without looking into the logic of how the loader works. > On Mar 11, 2021, at 9:55 PM, pd-list-request(a)lists.iem.at wrote: > > i wonder if this is intentional. > > i'm absolutely in favour that "-lib" loads libraries in the stdpath. > (i'm just mentioning this, even though i don't think that this is > actually the issue here) -------- Dan Wilcox @danomatika <http://twitter.com/danomatika> danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/>

declare: stdlib vs lib
by IOhannes m zmölnig 11 Mar '21

11 Mar '21

hi all, i just noticed that declaring a library with *both* '-lib' and '-stdlib' will load two libraries (if it can be found in the stdpath) e.g. [declare -lib bonk~ -stdlib bonk~] this will load bonk~ twice. typically it will load the same library twice: once it's found in the stdpath, and the other time it's found in the normal paths (that include the stdpath). sometimes two different binaries are loaded, iff the there's a library with the same name is also found in a non-stdpath. i wonder if this is intentional. i'm absolutely in favour that "-lib" loads libraries in the stdpath. (i'm just mentioning this, even though i don't think that this is actually the issue here) typically, libraries are not loaded multiple times and there is special code that tries to prevent duplicate loading. however, this code does not kick in when using both -stdlib and -lib. is this intentional? gmfds IOhannes
