Re: [PD-dev] multichannel signals, preliminary support
by Dan Wilcox 18 Jan '23

18 Jan '23

I'm fine with objects like [osc~] not being multichannel is there is an easy way to parallelize / multiplex instances ... ie. clone. For consistency, one might want the Max approach of providing alternate versions of *all* dip objects, but if that's too much code overhead and we can concentrate this into clone or a similar object, it makes sense to me. >> Incidentally, now I think the word "distribute" is ambiguous - does anyone >> have a better word for packing/unpacking on way in and out of clones? >> > > fan-in/fan-out? ('fi', 'fo') I also thought of "fan in" and "fan out" ... probably to the consternation of IOhannes who added the "triggerize" feature. ;) -------- Dan Wilcox @danomatika <http://twitter.com/danomatika> danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/>

Re: [PD-dev] Send~ and receive does not allow you to change name with a symbol!
by Dan Wilcox 17 Jan '23

I was thinking the same. Also, if the concern is "too many dsp objects", put them in sub patches / abstractions and use [switch~] to turn them off. This is what I do in our spatialization server patches at work where there are 4 levels of channel routing between 64 objects on each level. For instance, if there are only 4 outputs, all the other outputs are "switched off." > On Jan 17, 2023, at 8:47 PM, pd-dev-request(a)lists.iem.at wrote: > > Message: 3 > Date: Tue, 17 Jan 2023 16:47:27 -0300 > From: Alexandre Torres Porres <porres(a)gmail.com <mailto:porres@gmail.com>> > To: Christof Ressi <info(a)christofressi.com <mailto:info@christofressi.com>> > Cc: pd-dev(a)lists.iem.at <mailto:pd-dev@lists.iem.at>, msp(a)ucsd.edu <mailto:msp@ucsd.edu> > Subject: Re: [PD-dev] Send~ and receive does not allow you to change > name with a symbol! > Message-ID: > <CAEAsFmgfeWnJTG4o4k6mrpK-S=waz+3n4OK8c9WvypZXMS6onA(a)mail.gmail.com <mailto:CAEAsFmgfeWnJTG4o4k6mrpK-S=waz+3n4OK8c9WvypZXMS6onA@mail.gmail.com>> > Content-Type: text/plain; charset="utf-8" > > so, [throw~] can set the destination, why not use it? -------- Dan Wilcox @danomatika <http://twitter.com/danomatika> danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/>

rpole~ / cpole~ infs and nans
by Matt Barber 17 Jan '23

17 Jan '23

Hello, Should I be getting infs and nans in rpole~ and cpole~ (0.53-1, Mac M1)? Does this mean PD_BIGORSMALL() is not working correctly? [image: image.png]

Re: [PD-dev] [leapmotion] 2.3.1 linking failure on Windows
by Christof Ressi 05 Jan '23

Thanks! I would say, distribute everything /except kernel32.dll/ (this one is always present on Windows) ucrtbase(d).dll (Universal C Runtime) is always present on Windows 10, but not necessarily on older Windows versions. BTW, ucrtbased.dll is the debug version of ucrtbase.dll (without 'd'). Alternatively, you might also try to link statically with the /MT option: https://learn.microsoft.com/en-us/cpp/build/reference/md-mt-ld-use-run-time… Christof On 05.01.2023 21:31, William Brent wrote: > Thanks for all the tips Christof, here's a Dropbox link to a .zip of > the external: > https://www.dropbox.com/s/v45itm3lrwsxaax/leapmotion.zip?dl=0 > > > On Thu, Jan 5, 2023 at 10:21 AM Christof Ressi > <info(a)christofressi.com> wrote: > > > so...just one last question (hopefully): what's the best > practice for > > packaging an external like this?

[leapmotion] 2.3.1 linking failure on Windows
by William Brent 05 Jan '23

05 Jan '23

Hello all, I'm finishing up work on new [leapmotion] and [ultraleap] externals and trying to make them available for all compatible platforms (I'll skip the rundown of which hardware and SDKs work on which platforms here unless it's helpful). I've got everything working except the [leapmotion] external for Windows. I'm using pd-lib-builder and MSYS2 MinGW 64-bit and am able to compile successfully, but linking to the 64-bit Leap library fails with a stream of "undefined reference to" messages. I'm positive that gcc can find the Leap.h header and the Leap.lib/Leap.dll libraries in my Leap SDK 2.3.1 directory, and have done a nearly identical build process for the [ultraleap] using the LeapC SDK 5.7.2 where linking succeeds and everything works fine. I'd be very grateful if anyone could shed some light on what I'm doing wrong here. There's no need for any Leap hardware for building, you just need to clone my [leapmotion] repo here: https://github.com/wbrent/leapmotion and download Leap SDK version 2.3.1 for Windows here: https://developer.leapmotion.com/releases >From there it's just a matter of editing the Makefile to specify your Leap SDK directory location and attempting a "make" in MSYS2. I'm using Windows 10 Home, Pd 0.53-1 (amd64-32), and pd-lib-builder version 0.6.0. Below is a truncated version of what I get in my attempts. Any suggestions or further questions are welcome, thanks!

[sqrt~] precision & documentation
by Sebastian Shader 15 Dec '22

15 Dec '22

I've always been under the impression that [sqrt~] was more precise than [q8_sqrt~]The help file seems to reflect this. (saying sqrt~ is 20 bits accuracy, but q8_sqrt~ is only 8) However, the source in d_math.c seems to indicate that they are actually the same class/perform method: sigsqrt_class = class_new(gensym("sqrt~"), (t_newmethod)sigsqrt_new, 0, sizeof(t_sigsqrt), 0, 0);class_addcreator(sigsqrt_new, gensym("q8_sqrt~"), 0); am I missing something, or is the documentation incorrect about them being different?

Unconnected signals
by David Rush 14 Dec '22

14 Dec '22

Hi y'all Maybe this is something I missed in documentation, but how is one meant to tell if a signal inlet is connected or not when you get the dsp method call? I'm experiencing some artifacts in an external that otherwise works quite well, if I have gaps in its set of input signals (6 of them in this instance) actually connected. I have read the signal processing chain setup code in the past, but I haven't retained very much from that read. Is there something easy that I have missed? d -- GPG Public key at http://cyber-rush.org/drr/gpg-public-key.txt

jack_patch external
by Roman Haefeli 11 Dec '22

11 Dec '22

Hey all I revived the old jackx external from 2003 and re-designed it to my needs and my sense of a usable interface. Before I make a release proper with Deken binaries, I want to take the chance to make any (drastic or not) changes before its in the wild. Any comments are welcome. I had difficulties deciding between sink/source and input/output terminology. input/output are somewhat ambiguous, because soundcard input is an output from JACK's perspective. However, input/output is what is used in JACK's internal naming, so I stuck with it. https://github.com/pd-externals/jack_patch Roman

TO pd dev - I'm fixing to make a bugfix release. I just merged 'develop' and 'Documentation'. Anything else (fixes only, please, no new features) that I should look at? thanks Miller
