Re: [PD] comparing symbols in external
Strange things like this can happen if someone inadvertently writes
a new string into an existing symbol... i.e., never do this:
strcat(sym-s_name, cat).
MAybe there was already a symbol somewhere else whose name is cat and
then you'll have 2 symbols with teh same name but different addresses.
(I've seen people do this, in various ways, before).

Re: [PD] best format for send/receive between iOS and libPD
Hi Matt - From Pd's perspective at least, it would be more efficient to handle the messages separately (some of Pd's list operations have to copy the list, which would be expensive if done iteratively over a long list). cheers Miller On Wed, Apr 30, 2014 at 01:37:05PM +0900, i go bananas wrote: I've got a six voice synth, each with about 20 variable parameters, and then sequence data, etc... and all of this data is being stored by the objective C front-end of my app. can someone tell me, hopefully from experience, what the best format is to send a lot of pattern data between obj C and libPD ??? should i package all the data as one huge list, or break it all into individual variables, or is it ok to organize it into groups for ease of management. my plan was to send messages like this from obj C: to [r instr1_pattern_data] : [vol 0.8, pan 0.5, pitch 0.75, param1 0.99 ... etc] actually, i'm not the one doing the C coding, i'm, just doing the pd side, but i have to prepare things on my end to make it flow as well as possible.

Re: [PD] pitch to voltage
That is an excellent, witty way to measure pulse withs using only tilde obects - my hat's off to you. The methond only has limited accuracy since its measurement is in samples. For instance, a 1/2 cycle of a 440-hz. tone at 44.1 kHz is only 50 samples, so there's only 2% accuracy. That's about 1/3 of a half tone (30-ish cents) which would sound horribly out of tune. There's an alternative sine-to-sawtooth recipe described here: http://msp.ucsd.edu/Publications/icmc10.pdf This is the basis of my guitar processing patch, smeck, but should be more broadly useful. But it has its own limitations: the sawtooth you get out is wiggly if the input sn't a pure sinusoid. There's also the possibility of simply pitch tracking with sigmund~.

Re: [PD] pitch to voltage
Sorry for the double answer, but this also occurs to me: To improve accuracy, measure both halves of the cycle and add them. To improve further, upsample the whole mess, say by a factor of 16. Doint both of those would improve the theoretical resolution by a factor of 32.

Hi Federico - tabread4~ doesn't interpolate between values of the input signal, or to put it another way, whast it does as a result of any input sample has no effect on what it will do on the next one.

Re: [PD] [PD-dev] oggread~ not working on pd-extended or libpd on windows.
I THink it should really be:
if((x-x_file = sys_fopen(filename-s_name, r)) == 0)
sys_fopen returns NULL (also known as 0) on failure, otherwise a pointer;
it makes no sense to check the sign of a pointer as far as I know.

I have tried pd-extended (both installer and standalone) and I

Any ideas on how to make this work? What kind of debug info can

I've found that this problem is particularly obvious with minpower. The sound file I'm playing through sigmund has peaks varying mostly between 60 and 80, with occasional peaks around 90 (according to sigmund's env output). To my understanding the help file suggest that a value of minpower around 50 should detect pretty much all the notes, and a value around 90 would detect almost none. But in practice I find that there's almost no difference. I have to use values of minpower around 100 and 130, with 130 having the effect of effectively making sigmund output no notes at all. Is it a normal behaviour? Is there something I don't get in the way sigmund's work?

Re: [PD] Peak Level detect in Vanilla
By the way - I just looked, and you can save a great deal of trouble using the array max object (new in Pd 0.25) - no need for 'until' horror. (just put the abs~ of the signal into the table). But env~ seems incomplete to me if it's only going to compute RMS. cheers M On Sun, Mar 09, 2014 at 09:36:31PM +0100, Roman Haefeli wrote: On Son, 2014-03-09 at 12:23 -0300, Alexandre Torres Porres wrote: As far as Vanilla goes it does seem like a great solution.

Re: [PD] jack and callbacks
The callback flag instructs the Pd scheduler to run within callbacks from the audio system; otherwise the audio system might still be opened in callback mode (in portaudio or jack) or not (in alsa or mmio) but if yes, the scheduler and the callback routine communicate via FIFOs...

Re: [PD] t_scalar member sc_vec
It's more efficient (especially in terms of memory) to keep the two things contiguously in memory than to have to chase an additional pointer to the array. In C it looks almost the same (arrays and their pointers are both specified by naming the arraym but sizeof will act differently for instance. And yes, the growable part of a structure has to be the last thing for it to work.

Re: [PD] t_scalar member sc_vec
Hi all -
I don't know if this is a reasonable thing to do in 2014 - it's a coding trope
I learned around 1981. As far as I know C has no clean way to describe a
packed data structure with a header and then a variable number of identical
elements (like a soundfile with a header followed by samples). In this case,
the object consists of a structure,
t_gobj sc_gobj;
t_symbol *sc_template;
followed in memory by an array of t_words. One can't make a zero-size arary
in standard C (as far as I know) and so it's declared as having the artificial
size 1. If there are n elements, the size of the structure is
sizeof(t_scalar) + (n-1) * sizeof(t_word)
subtracting 1 for the one that stood in for the array.
cheers

Re: [PD] Is Audio Settings Use Multiple Devices available on Mac OSX?
Hi Santiago - Pd uses Portaudio to talk to CoreAudio. It loks like there's no reason one couldn't fix the code to offer multiple devices (although it still wouldn't work for Portaudio/ASIO because ASIO apparently doesn't permit it). One reason I haven't done that is that Soundflower (if I understand correctly) does a decent job of it, probably better than I would be able to do, so I don't see an urgent need. (Also, allowing multiple devices complicates the code and can easily introduce problems; I've spent a lot of time fiddling with multiple-device support in ALSA and MMIO and have come to feel that it's an endless time sink.) cheers Miller 2002 when multiple devices weren't allowed (as far as I know).

I think this is probably best fixed by fixing the example to say that it's showing phase delay, not phase response, or equivalently, saying it's -arg(H) instead of arg(H)... this is probably also wrong in the book. I'd better go look when I have a moment... thanks Miller On Thu, Feb 13, 2014 at 11:35:20PM +0100, Peter P. wrote: Hi list, just wondering if I am getting something wrong plotting the phase response of lop~ using the abstractions filter-graph1.pd and filter-graph2.pd as exemplified in 3.audio.examples/H10.measurement.pd For a simple one-zero lowpass filter using [rzero~ -1] the phase response is plotted going from 0 to pi/2 (eg. 90°) at nyquist frequency.

Re: [PD] vst~ for OSX, any update?
Hi all - I tried to do this a while back but found out that on Mac you have to structure a program as an app (which entails using Apple's event loop instead of your own scheduler). I couldn't see any reasonable way to get Pd working that way, and eventually gave up. My workaround was to use another application to show the GUI, learned the controls and found reasonable settings, and then used the plug-in in Pd with no GUI. By the way, at the time there seemed to be NO open-source program for Macintosh that could host plug-ins. I ended up using Max :) Miller On Wed, Feb 12, 2014 at 06:32:04PM +, Pagano, Patrick wrote: Hello I am asking if anyone has had any success on updating the vst~ object for OSX.

Re: [PD] how to specify literals as type t_float
Hi Katya - I think there's no simpler way. On the other hand, for constants like 0.125 and 2, it would be equivalent to say 0.125f, etc - but for other constants (1/3 for example), casting as t_float would be more accurate in case t_float is set to double. I think people rarely use t_float as higher precision than 32 bits though, and even if they did the difference between (t_float)1/(t_float)3 and 1.f/3.f is pretty small. cheers Miller On Mon, Feb 10, 2014 at 10:53:02PM +0100, katja wrote: Hello, When working on parabolic interpolation in a Pd class, I wondered again what is the best method to specify literal constants as Pd's type t_float (which could be float or double). The interpolation goes like: ... t_float a = buf[peakindex-1]; t_float b = buf[peakindex]; t_float c = buf[peakindex+1]; t_float realpeak; realpeak = b + 0.125 * (c - a) * (c - a) / (2. * b - a - c); ... Without float suffixes for the literals, single precision t_float variables would be promoted to double here, which would be an unintended waste of CPU cycles. For some time, I've worked around this by using const variables instead of literals, like: ... const t_float two = 2.; const t_float eighth = 0.125; t_float a = buf[peakindex-1]; t_float b = buf[peakindex]; t_float c = buf[peakindex+1]; t_float realpeak; realpeak = b + eighth * (c - a) * (c - a) / (two * b - a - c); ... While this avoids redundant type conversions, it clutters the code and does not result in such fast instructions as literals do. Therefore I am now using type casts where type specifiers are normally used: ... t_float a = buf[peakindex-1]; t_float b = buf[peakindex]; t_float c = buf[peakindex+1]; t_float realpeak; realpeak = b + (t_float)0.125 * (c - a) * (c - a) / ((t_float)2. * b - a - c); ... For the above code I have checked assembly output as generated by GCC with -O3 optimization on Linux i386. Using literals without type specification, the whole routine is done on the FPU (80 bits precision). With the literals cast to t_float, it is done with single precision instructions for XMM registers. As far as I can see, casting literals to t_float results in the same assembly output as using the float specifier. For single precision t_float, '(t_float)0.125' is equivalent to '0.125f'. I can't think of a disadvantage, but let me know if I overlooked something.

rebuilding all of Pd. Doing make in the src directory of 0.45
only rebuilds the things that need to recompile, but it doesn't
update the binary, which makes it useless.

Re: [PD] console font size really big
Better than changing the font size globaly would be to change the
font sizes in tcl/pdwindow.tcl to negative numbers, which has the same
effect but only locally (instead of nuking everything. The particular one
is:
text .pdwindow.text -relief raised -bd 2 -font {-size 10} \
-highlightthickness 0 -borderwidth 1 -relief flat \
-yscrollcommand .pdwindow.scroll set -width 60 \
-undo false -autoseparators false -maxundo 1 -takefocus 0
(change size 10 to size -10.)
Now I should think about whether to do that in the Pd source :)

Would be interesting to know wonder what the deletrious effects were.
Tk has a very friendly but very small community without the
resources to make sure everything works as advertised across all
platforms. So depending on which platform you use you'll see
different symptoms, depending on how well tk is integrated with the
guts of the window manager (in GNU/Linux, this would be not at
all), the accuracy of the info delivered to Tk from the OS/window
manager, implementation features/bugs in a particular graphics
subsystem, etc.
One detail is that if you let [tk scaling] do its thing, you'll see
problems in the postscript output if you print a patch. There's an
ugly fix somewhere for this which requires hacking the ps output to
scale it by the tk scaling factor.
But if you hard code tk scaling to 1 users on Windows will see font
problems from Tk's half-baked, hardly documented theming engine that
would require _really_ ugly hacks all over Pd to fix.

Re: [PD] jack periods 32 = no pd
OK... that's really quite strange indeed. FWIW the 'mmap' alsa code, as far as I know, is only selected for RME devices. I don't have any of those handy so have little way to check any of this on my end. It was written by Winfried Ritsch a decade or more ago :) Miller Made a latency test with pd's own latency testing patch /usr/local/lib/pd/doc/7.stuff/tools/latency.pd -alsa -rt -audiobuf 2 -channels 18 on an HDSPe card with Multiface and a loopback analogue cable gives 6.5ms, which I consider great! Interestingly Pd gives this latency value regardless of setting -audiobuf to values 1-6, which I suppose is because of rounding this value to something usable by the dsp part. Pd also reports on startup ...buffer_time 2902 us opened using mmap audio interface Now what is weird, is that I can't get clean audio under alsa with any values larger than -audiobuf 6. The sound is very distorted. Using the -oss emulation and -rt, clean audio is available for values larger than -audiobuf 2 such as: -audiobuf 3 with measured latency of 7.9ms (Pd choses blocksze 56) -audiobuf 5 with measured latency of 9.4ms (Pd choses blocksze 56) -audiobuf 6 with measured latency of 10.9ms (Pd choses blocksze 56) and so on. Oh this is on a Debian system running kernel 3.2.0-4-rt-amd64 Nice that Pd can do so low latencies, but that's a strange thing about alsa though... best, P ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Re: [PD] jack periods 32 = no pd
Probably that's so - but Pd should still be able to deal with the mismatch. OTOH, since Pd is built-in 64 blocksize, you wouldn't be able to reduce Pd's latency by reducing jack's blocksize below 64. I'm not sure about this, but I believe that Pd running standalone (using ALSA driver) can achieve as low or perhaps slightly lower latency than Pd running under jack. This is only of interest if Pd's the only audio application you're running on that particular audio interface, however. cheers Miller On Tue, Jan 28, 2014 at 12:33:43AM -0500, pured...@11h11.com wrote: hum i might have an idea why: is it because pd works in 64 blocks? ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

The object width is saved in the patch by using an yet unused mechanism.

Before that change, Pd files could be treated as fully FUDI compliant. It was possible to use [textfile] to read and process Pd files. After saving, those files were still functional Pd files. Since the new feature, Pd files cannot be processed in the same manner. A message box as defined above results in: #X msg 93 110 bla; f 35; The resulting Pd file is corrupt and cannot be parsed by Pd anymore. I considered it a great advantage that the same protocol was used consistently throughout Pd. Though it might not have been an advertised feature, it made a lot of sense to me and I've been exploiting it. netpd now suffers from that new feature because it uses [textfile] to read and transfer patches between clients. Any patch that was made in Pd 0.45 and uses manually altered object widths breaks horribly when transferred. Miller suggested to use the newly introduced [text] object instead [1]. It allows to export a bunch of FUDI messages (or a Pd file, so to speak) as one single list. Regarding the problem above, that surprisingly even works for Pd files that use the new feature. The problem I face is that OSC packets have a maximum size and some Pd files are too large to fit into one OSC packet. I could split them up, but with lists there is no way to tell how many bytes they are using (you can only measure the number of atoms). I'm writing to the list to raise awareness of the issue. As 0.45 is still fresh, the new format may not be yet carved in stone. It might also be the case that I'm the only one who cares. Well, scrap it then. Roman [1] Check that out if you haven't already.

Re: [PD] headroom in Pd

Re: [PD] Ugly looking fonts in printed postscript patches on MacOsX
Hi all -
I've used awk scripts. The exact thing to do depends on font size and on
windowing system. Most recently my awk script was this:
BEGIN {last = -10}
/findfont 8/ {
last=NR
$1 = /Courier-Bold
$3 = 11.7 + 2
}
{
if (NR == last+2) {
$1 = $1+1
$2 = $2-3
}
print
}

I am just about to finish a Turkish book about Pure Data. I am writing my

Any ideas ?

There could be something wrong. But array_random_bang() (in x_array.c) cooks up a pseudorandom number from 0 to 1 (I believe) and then calls array_quantile_float() with it.

Aha and bngo! In effect - array random is only looking at the lower 1/2 of the distribution. I made a stupid C data type fumble in the code.

Re: [PD] using multiple asio devices
I've never done this (and Pd doesn't support multiple devices through portaudio which is the only path into ASIO that I know of). If I were doing this I'd re-write s_audio_pa.c to support multiple portaudio devices -- but I'm not sure ASIO itself is capable of this! If it turns out that only one ASIO device may be open per process, the only out I can see is to write an extern that kicks up a new process (or perhaps use pd~ to make the process so that the extern need only open ASIO within the existing process).

Re: [PD] Mac: 64 bits faster than 32
I tried this on linux some years ago and got maybe 15% faster execution in 64 bits than 32 (on the same 64 bit machine).

Re: [PD] Building externals on OSX
THat agrees with my experience I compile Pd vanlla on a 32-bit machine running 10.4 (I believe) and it's perfectly happy to grind out 3-architecture binary externs. (If you look in 32-bit Pd vanilla you'll see that sigmund~, etc, are OK fro PPC, i386, or whatever-you-call-it 64 bit intel. (Only gotcha is taht I can't compile teh 64 bit app that way - I have to squat on a newer machine for that, so teh exxterns included with 64 bit Pd vanilla are lacking PPC support. I don't know of any way to compile PPC apps anymore. I would be happy to put out a PPC version of Pd if I could. cheers Miller On Mon, Oct 21, 2013 at 09:38:06PM -0400, Dan Wilcox wrote: Errr.

The only reliabel way to use an old machine with 10.5 or 10.6 and an old version of Xcode, probably Xcode 3.something. IMHO, at this point, it's best to drop support for PPC for new versions of pd.

Re: [PD] declare and abstraction
There's a long-standing bug with putting declares in abstractions (they affect the way the _parent_ patch searches for patches, not the abstraction itself.) It's on my dolist to try to restore sanity to the situation somehow (compatibly) but I won't be able to do that anytime soon. So, yes, for now put all the declares in the toplevel. cheers Miller On Tue, Oct 08, 2013 at 05:16:17PM +0200, Cyrille Henry wrote: hello, thanks, but i really want to be able to work on patch1 without having to open patch. c Le 08/10/2013 16:30, Frank Barknecht a écrit : Hi Cyrille, I struggled with that for a long time myself. Unless something changed in 0.44/0.45 the only really reliable solution I found was to *only* use [declare] in a *toplevel* file, and never in any abstraction.

It's included in vanilla, but there license is different, etc etc... When we looked into it, we found that the original license for expr was in fact LGPL, not GPL, as stated in the pd documentation. (So, as Iohannas suggests, a bug report might be a good idea) When i asked about the possibility of changing to the pd style BSD license, Mr Yadegari was totally fine with that, and said that is what he had wished anyway. However, the expr license was now under control of the university, and i would have to contact the relevant people to ask about changing the license to BSD. In the meantime, i had called Apple, and asked about the legality of GPL, and they said GPL was not permitted, as you need to release the code with the app, and they don't have that facility built in to their app store. Then when i asked about the possibility of LGPL, which doesn't need the source code included in the package, they sent me from person to person, and i never got a straight answer... basically they told me that if i wanted to use LGPL, i would have to hire a lawyer to speak with their lawyer. Soit seemed like changing the expr license to BSD would be the best option. I contacted another developer who Mr Yadegari referred me to, and we spoke about the possibility of changing the license. He said no one had touched expr for years, but couldn't see any reason why not to change it. He said he'd need to check with the relevant department at the university, and with the other developers who had taken on the caretaking of expr. And then, university summer holidays started, before i could go any further, and i never heard back again about the license. So, as far as i understand, the expr developers i spoke to all seemed fine with the idea of BSD, but we just never got as far as getting everyone together and making the change.

Re: [PD] Legal restrictions for apps
Hi Tony - I'm not sure, but I always thought you can distribute LGPL objects within commercial (closed-source) software. If I'm wrong about that, the next step would be to re-rwite the patch without using expr~ and not include expr~ in the product. (I keep it as an extern to make that easy to do.) cheers Miller On Wed, Oct 02, 2013 at 11:32:21AM -0600, Tony Hillerson wrote: Hey guys, I'm wondering about the restrictions for using Pure Data patches in Android and iOS apps with libpd.

[PD] [PD-announce] pd 0.45-3 test 1 released
Hi all, Pd version 0.45-3 test 1 is available on http://crca.ucsd.edu/~msp/software.htm or via git from sourceforge: git clone git://git.code.sf.net/p/pure-data/pure-data cd pure-data git checkout -b 0.45 This fixes the bug pasting text from other software into Pd boxes, and also fixes (I hope) the problems with running at 48KHz on built-in hardware on Mac OSX 10.7 and 10.8. Since this is a change in audio I/O that could have unexpected effects on other hardware I'm leaving it as a test version to see if anyone has new problems.

And why do indices 1 and 513 have different values too? do they? when it comes to floating point, equality becomes a little bit fuzzy. e.g. 0.1 is really the 'same' as 0.10001490116119384765625 [1]. comparing the values, you can see that they are not *very* wrong: array[512]-array[0] = -5.30668e-6 = -0.053 array[513]-array[1] = -5.30718e-6 = -0.053 array[514]-array[2] = -5.30668e-6 = -0.053 so the errors are really rather small, and hopefully don't matter so much in the interpolation (which is another approximation anyhow). the reason why the error is not smaller, is that Pd internally (src/g_array.c:896) deals with a PI value of 3.14159, which is a rather rough estimate and is the reason why the cycle is not exactly 512 points long. fgamsdr IOhannes [1] http://en.wikipedia.org/wiki/Floating_point#Representable_numbers.2C_conversion_and_rounding -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.14 (GNU/Linux) Comment: Using GnuPG with Icedove - http://www.enigmail.net/ iEYEARECAAYFAlIoY3UACgkQkX2Xpv6ydvTY1wCcDCyH8kY50snbVOv5AxwspIAB jwQAoLJOrVoESvzyqrZyvWKky0ec1eUT =YqkS -END PGP SIGNATURE- ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Hi all,

cool.
i started updating the Debian packages...
As always I'm sure there will be problems here and there - you're welcome
to report them on the Pd mailing list (pd-list@iem.at) which is always the
fastest way to get me to see them.
two smallish notes.
#1 CFLAGS
when manually including the Debian-patch usercflags (that makes sure
that user-specified CFLAGS are honoured by prepending the
configure-detected flags rather than appending), a small oversight has
occured:
- on *linux*, the configure-CFLAGS are still appended. instead the
change was made for *hurd* (aka GNU). i think this was simply a
confusion of GNU and linux.
- otoh. the *hurd* CFLAGS still include -O6
the attached usercflags.patch hopefully gets this right. it /also/
fixes the CFLAGS append/prepend order for cygwin mingw (though i admit
that i have not tested this)
#2 BUILD FAILURES with -Werror=format-security
when trying to build with the above error-flag (which pays some extra
attention to argument passing), the build fails due to two problems.
a) a call of error(buf) withing bug() is rejected, as the
'error'-function really reads error(const char *fmt, ...) and 'buf' is
not a format, resp. there are no varargs. the fix is simply to call
error(consistency check failed: %s, buf)
and not construct the consitency-failed string beforehand. cool, this
makes the code a little more readable!
b) more serious, the new [text] object uses 'pd_error(ouch %s, str)',
when pd_error() really needs a pointer to a pd-object...
this is a potential crasher bug, as it accesses string memory as objects.
the attached patch fix_format-security.patch fixes this as well.

Re: [PD] [PD-announce] pd 0.45-0 released
Well, not having a way to get a dual screen Mac I can't test this but here's a guess - it might still be that Pd refuses to allow negative window locations and so throws the abstraction below the visible portion of the smaller of the two screens. I don't know if Tcl/TK has any way of dealing with this I'll have a look but probably can't fix this very quickly. cheers Miller On Wed, Aug 28, 2013 at 07:56:58PM +0200, Max wrote: Am 23.08.2013 um 21:00 schrieb Miller Puckette m...@ucsd.edu: As always I'm sure there will be problems here and there - you're welcome to report them on the Pd mailing list (pd-list@iem.at) which is always the fastest way to get me to see them. There is a small bug for users of multiple monitors or resolutions (tested only on osx, but i guess that's platform independent). Some Pd versions ago the patches saved on a bigger resolution screen were opening off-screen when opened with a smaller resolution or only one monitor. This has been addressed since. In 0.45 if you have the main monitor on the right and a secondary on the left (thus having negative x values) if you save this patch on the secondary and open it again it will appear on the primary monitor, even if you have the second still attached. Subpatches and abstractions do show an even stranger behavior: if you have a patch open on the primary monitor and drag a subpatch on the secondary monitor (placement relative to the primary monitor doesn't matter here) then save and close the subpatch, open the subpatch again: you can't.

Re: [PD] outlet_float crashes on windows
The code looks good - unfortunately, in these cases I'm usually suspicious that
somewhere else in the code something is causing memory corruption. If you
can get to a linux machine you can try the wonderful 'valgrind' program that
is very god for tracking down bad memory references in C code.

Hi,
trying to compile an external for Windows XP I get a very strange
error: pd crashes when calling outlet_float on an external outlet

and Linux (same pd version, but has been running there for several
years). Bypassing the outlet_floats by sending to dedicated receivers
in the patch makes everything work as expected without any problems
(which makes it even stranger as it is a pretty involved external with
internal dynamic loading and connection of abstractions communicating
with internal in- and outlets with proxies using outlet_float and such
internally without any issues).
This is my first attempt with supporting Windows and my setup might be
screwed up, so I thought I'd ask on the list whether someone has an
idea how to further investigate into the problem. I'm compiling on a
virtual machine with XP and latest MinGW. I'm linking against a pd.dll
of pd-0.43-44 using all header files from that version as well. The
test is done with a pd of the same version.
Unfortunately I don't know anything about getting a debugger to work
on Windows. (I remember it was already painful to get it working with
inspection and breakpoints on my linux machine).
Below are the relevant code snippets of the external.
Any ideas?
