Delay (msec) option in audio properties
by Mario Buoninfante 14 May '19

Hi, Can anyone explain me what's the actual effect of 'Delay (msec)' parameter you can find in the audio properties dialog? Cheers, Mario

Shared buffer between multiple instances of PD
by Sebastian Lexer 14 May '19

14 May '19

Hi, I am wondering whether it is (at least theoretically) possible to create an array/buffer that is accessed from two instances of PD on the same computer. One of these instances would write/read from this buffer, the second would be read only. If possible, would you have any pointers how to realise this? Thanks, Sebastian

Comport problem with Arduino: 13 comes in as 10
by Ingo 14 May '19

14 May '19

Hi there! I'm getting number 10 instead of 13 from my adruino. I remember something that 13 is something like "end of line" or "carriage return". In some cases 13 was replaced by 10 for some sort of simplification - I don't remember any more details. What can I do to set up [comport] to output the correct numer 13 instead of 10? There should be a setting for not treating it as a "modem" ... Thanks! Ingo

Comport and Windows 10
by Malcolm Jackson 13 May '19

13 May '19

Hello, I'm currently going through ch.2 of Electronics for Digital Musicians by Alexandros Drymonitis. I'm at the part where he uses a [comport 7 57600] object in a serial_write-help patch to communicate with an arduino. I get this in the main window: [comport]: could not open device COM7: failure(2) ERROR_FILE_NOT_FOUND [comport] opening serial port 7 failed! I tried sending the devices message to it and it found the port my arduino was connected to. Should I just change the port number to that? I've been looking around and seeing that comport doesn't work with windows 10 but haven't found a solution. I appreciate any help.

Full stop '.' in class namespace
by Julian Brooks 12 May '19

12 May '19

Hi all, Is there a reason to not make use of a full stop in a namespace? E.G. [julianslib.dac~]? Cheers, J.

Re: [PD] Full stop '.' in class namespace
by Christof Ressi 12 May '19

I'm currently handling this in class_new, because this is where also the additional creators for abtractions and single-object-per-binary externals are added. but actually you're right: the extra creator is only registered for the "main" class name, but not for aliases added via class_addcreator. so after loading iemlib, you can do [iemlib/init] but not [iemlib/ii], while [ii] of course works. note that this is actually also an issue with single-object-per-binaries libraries which use class_addcreator. so I agree that it would be good to handle the automatic alias creation in class_addcreator. I will have a look. Gesendet: Sonntag, 12.

If a [declare -lib foo] is nested somewhere in [myAbstraction], wouldn't this algorithm erroneously add a "myAbstraction/foo" creator? -Jonathan

clarification on [coll] object - doesn't seem to be global
by Scott R. Looney 12 May '19

12 May '19

hi folks just a quick clarification on cyclone's [coll] object that i'm using in PD. i named mine [coll list] and i've loaded a text file into it. however, it seems like updates to the [coll list] object only seem to carry through all the coll objects in the active patch window. if you have a 'pd' subpatcher or you're in a subpatcher the changes don't seem to be propagating to the other subpatchers. if i load up the same text files in those subpatchers, they act like separate instances and are independent. as i recall the [coll] object in MaxMSP worked globally in all patch and subpatch windows as long as the name was the same. so i don't know if this is normal behavior but i need a global list of parameter names and values that can work through subpatches. i don't think textfile will work in this case, as i need to be able to look up text addresses and spit out a a parameter value at that address, which seems to be ideal for [coll] any help or clarification appreciated! thanks in advance... best, scott

Hi, just updated these again in a short period of time. Many bug fixes and improvements on this one, not that many new objects: https://github.com/porres/pd-else/releases/tag/v1.0-beta20 - binaries showing up anytime in deken. This has a new example the Pd Introduction folder about ecaping characters. https://github.com/porres/Live-Electronic-Music-Tutorial/releases/tag/v1.0-… cheers _______________________________________________ Pd-announce mailing list Pd-announce(a)lists.iem.at https://lists.puredata.info/listinfo/pd-announce

Strange Bug Crashing Pd (block + abstractions + fft)
by José de Abreu 08 May '19

08 May '19

Hello List. I'm on Pd 0.49 on linux ubuntustudio lsb_release -a shows Ubuntu 18.04.2 LTS short version: open the zip folder and start "UsandoFftHanning.pd" and try to click on any set message that goes to block~. Here it crashes everything. long version: I was trying to create simple abstractions that could help me creating a hanning window and using simple fft to show spectrum in a parent patch. I was experiencing problems with tabwrite~ + metro 100 because it was not writing in the start of array1 (like dc frequency was 3/4 in the array instead of the start of the array), so i suspected that maybe if i used [metro 1028 1 samp] it would work. It doesn't help... So i put a [block~ 1024] and voila it worked. But this is strange because i wanted to see it at normal block, since i want to use dac~ and etc... then i created a bunch of [set( messages to control block to see where it works fine or not. Here it started the bug. whenever a click on wherever set message, pd crashes. if i try to close the patch it crashes, if i try to open any abstraction it crashes, if i try to stop metro it crashes... it literally crashes with any action i believe... can someone test if opening UsandoFftHanning.pd does the same thing? i don't know how to report this bug since i don't know what makes it crash...

Re: [PD] pd-lork and midi on osX
by Dan Wilcox 07 May '19

07 May '19

If there is nothing really wrong with that define, we could just set it when building port midi. See portmidi/Makefile.am/... Unless the system has issues with it, it would be good to have closer behavior between operating systems. In general, Pd doesn't;t really stop you from flooding the output anyway... > On May 5, 2019, at 10:48 PM, pd-list-request(a)lists.iem.at wrote: > > From: "Christof Ressi" <christof.ressi(a)gmx.at <mailto:christof.ressi@gmx.at>> > To: pd-list <pd-list(a)iem.at <mailto:pd-list@iem.at>>, "cyrille henry" <ch(a)chnry.net <mailto:ch@chnry.net>> > Subject: Re: [PD] pd-lork and midi on osX > Message-ID: > <trinity-6ecc9a45-cc9d-40d3-847f-663d62a161fa-1557088965253@3c-app-gmx-bs23> > > Content-Type: text/plain; charset=UTF-8 > > PS: I think you can actually disable the speedlimit with "#define LIMIT_RATE 0" in pmmacosxcm.c. This should give you the original Pd extended behavior. -------- Dan Wilcox @danomatika <http://twitter.com/danomatika> danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/>
