messages FROM pd ? ...
by oliver 17 May '17

17 May '17

hi, dear list ! i know about the messages that can be sent TO pd, but i recently read (in the help file for [samplerate~]) that pd sends a bang to a [receive pd-dsp-started] object when the dsp is started. of course the same works for [receive pd-dsp-stopped] when it is stopped. that's a nice feature ! are there any other useful messages that can be received by specially named receive objects ? (like mouse coordinates, mousestate, window coordinates, save state, closing state ...) there seems to be no documentation on this one ... best oliver

I agree. Maybe someone can check the sources and whip up an example patch? This reminds me that there is that nice set of messaging examples (ie. opening/closing a subpatch, open/closing patches, etc) that came with Pd-Extended which would be nice to now include with vanilla. > On May 16, 2017, at 2:13 PM, pd-list-request(a)lists.iem.at wrote: > > From: oliver <oliver(a)klingt.org <mailto:oliver@klingt.org>> > Subject: [PD] messages FROM pd ? ... > Date: May 16, 2017 at 10:45:55 AM MDT > To: pd-list(a)mail.iem.at <mailto:pd-list@mail.iem.at> > > > hi, dear list ! > > i know about the messages that can be sent TO pd, but i recently read (in the help file for [samplerate~]) that pd sends a bang to a > > [receive pd-dsp-started] > > object when the dsp is started. of course the same works for > > [receive pd-dsp-stopped] > > when it is stopped. > > > that's a nice feature ! > > are there any other useful messages that can be received by specially named receive objects ?

[lsl_inlet] released
by David Medine 16 May '17

16 May '17

Dear all, I have released the first of at least two objects that leverage labstreaminglayer (LSL) in Pd. For those unfamiliar with LSL, there is a blurb at the bottom. So far I have only created a marker inlet object, but I have plans to make a marker outlet and corresponding DSP objects to handle real-time data streaming as well. However, making the DSP externs requires up/downsampling and all the associated issues with buffering, memory management, and filtering that come along for the ride whenever you do that---so I don't know when that will actually happen. For now, this is a nice way to get discrete messages from (for example) an eye tracker into your Pd patch. It's also a handy way just to pipe messages between different languages (e.g. from python to Pd and back). I've only compiled this under Windows so far, but soon I will put (fairly modern) Linux binaries on the github hosting as well. OSX users will have to roll their own. Source and binaries here: https://github.com/dmedine/PdLSL If you use this and find any bugs, please post to the github issues page. About LSL: Labstreaminglayer (LSL) is a robust tool for streaming and synchronizing multi-modal data streams across a local area network. It was developed primarily for the purpose of multi-modal data acquisition in the context of complicated mind/body research experiments involving EEG, other bio-physical data acquisition, and the logging of stimulus markers. It is open source and cross-platform, although most of the hardware devices it supports have drivers for Windows only. It was initially developed by Christian Köthe at the Swarz Center for Compuational Neuroscience and has a growing number of contributors from around the world.

pd~ for running splitbank from lyon potpourri on raspi/organelle
by Pagano, Patrick 12 May '17

12 May '17

hello i am trying to run an external called splitbank~ and i think it's a bit too heavy for the rapsi inside the Organelle but someone suggested i try pd~ which made me realize i have never used it. I am not understanding the help patch and my hope is to offset some of the processing so perhaps it might run. has anyone got any patches that use it that i may learn form? I'va attached the file + a pd_darwin in case someone can look at it it would make a dreamy audio effect Patrick Pagano B.S, M.F.A Assistant Professor in Residence Digital Media & Design Web & Interactive Technologies University of Connecticut, Stamford (352)-226-2016

how to build multiple objects from one file
by David Medine 12 May '17

12 May '17

I am building a small suite of related externals and it would be most convenient to simply compile one .obj file and pull the externs off of it one at a time. My makefile is the standard Pd makefile, but I leave the CSYM and current fields empty so I can declare them with my call to make: >> make CSYM=lsl_inlet current=pd_nt It builds just fine, but when I open the help patch, the extern doesn't load. If, I rename the file and arrange things so that the filename is the same as the extern name (i.e. there is only one extern per .obj) and recompile it works just fine. The important point is that I don't change the code or the body of the makefile at all (except for the NAME field). I know that Miller does this it this way all the time, e.g. d_arithmetic.c. Any suggestions? Below is my makefile, in case that helps.

Array operations
by Pagano, Patrick 12 May '17

12 May '17

Hello http://mtlasm.blogspot.com/p/count-to.html I am emulating a Count to Five stomp box functions with pure data on the organelle and i am wondering if anyone has links or resources regarding fun/unique operations on arrays? I found Arraycopy in maxlib which copys the arrays quickly which is awesome, but i also want to play the contents of the array backwards and maybe scrub through the contents so i am hoping for some programming suggestions. one caveat is that there is no GUI on the organelle except for a menu, it has 4 knobs for parameter values [with multiple pages available and a volume knob/encoder knob thanks in advance. I got a suggestion to look at tabread4~ but any other externals that might compile on arch linux or other research regarding arrays would be interesting thanks~ Patrick <http://mtlasm.blogspot.com/p/count-to.html> [http://3.bp.blogspot.com/-DRIXBAFSn6E/UwOQoHlOo5I/AAAAAAAACOM/nxov-KNwkkI/s…]<http://mtlasm.blogspot.com/p/count-to.html> Montreal Assembly - Count to Five<http://mtlasm.blogspot.com/p/count-to.html> mtlasm.blogspot.com Count to five is a unique delay/sampler that offers many sonic possibilities. These are best shown by demonstration in the videos above below.
