Reading multiplexed data from an Arduino
by Alexandros Drymonitis 28 Mar '13

28 Mar '13

I'm trying to use two multiplexers, one with 16 potentiometers and the other with 16 buttons, to read the data in Pd. The potentiometers work fine, but I get nothing from the buttons. Wiring look correct (I've tried it with a single button and it works), so I've no idea what goes wrong. I've attached the Arduino sketch and the Pd patch if anyone's willing to give it a look. Thanks

making an external
by Pagano, Patrick 27 Mar '13

27 Mar '13

Hello I just got a copy of Eric Lyon's book, Designing objects for Max and Pd. My idea is to turn some of Christopher Penrose's cool C code of wacky PV command line apps into a working pd external. The file is called aphrodite and it does some truly interestingstuff to soundfiles. Alas, I am a noobie when it comes to compiling and external, so I am posting this to the list with hopes of getting some help cleaning up the code and turning the code into a working aphrodite.pd_darwin. Would anyone on list be willing to help me get started and from this experience be able to continue to convert this cool code into a suite of cool PV externals? I have attached a .zip of .c file and pv.h and helper.h and a makefile Please let me know if anyone can or is willing to help me understand this process. Thanks Patrick

Lexus Grant 2012 - electro-mechanical piano (player piano) - Solenoid Issue
by Epic Jefferson 26 Mar '13

26 Mar '13

Hey guys, I'm building a Pd controlled player-piano similar to Winfried Ritsch's autoklavierspieler as seen here http://vimeo.com/31561361. I found some documentation here http://algo.mur.at/projects/autoklavierspieler but I'm having trouble finding out which solenoid to use. I tried to contact him directly but have had no luck. If anyone has any recommendations on where to get solenoids with similar secifications to Winfried's or where i can contact him, please let me know.

vanilla replacement for polygate~ ?
by Patrick Pagano 26 Mar '13

26 Mar '13

Hello I was wondering if anyone had an idea for a Vanilla replacement for polygate~, which is listed as a switch between multiple signal inputs. I would like to make a patch for IPAD/MOBmuPLat that has this in the patch but i am wondering what a good vanilla substitute might be for it? polygate~ switch between multiple signal inputs variable fade rate both linear & equal power

Ardour as a vst host for pd manipulation?
by Jm Jones 26 Mar '13

26 Mar '13

Hi, Im a long time linux user but in the music area im stuck to windows. I use Ableton live and my actual interest is to control virtual instruments hosted by Live with pd and then record them. My notebook is not super powerful (2 core, 2gb ram) and i tough that maybe Linux will be more stable in a live performance involving PD, Gem and a vst host. So, is linux really more stable/faster, specially in the GEM area (i find it very resource hungry)? and is Ardour a good alternative for Live as a host? I just read that Ardour 3 is finally out, seems a big update. This is not a windows vs linux or ardour vs live, i want to know the real experience of people in this kind of workflow. Of course that ableton is for live situations and ardour a clasic DAW, but in this case the clip launching of live isn't necessary. -- JM Jones

remove commas from list, logic of make_my_list
by David Welch 25 Mar '13

25 Mar '13

Hi all, I'm working on a patch that is getting a stream of comma separated values from an Arduino device. Is there an easy way to remove them? Right now I am using the comport object and associated objects. I have modified the following subpatch, but the commas are getting pointlessly sent to a downstream unpack object. If anyone would care to explain what's going on here in this bit of magic as well, that would also be awespme. David

readsf fails to read 32 bits float wav
by Charles Goyard 24 Mar '13

24 Mar '13

Hi, today I noticed a readsf~ (on vanilla) opening a 5 wave file containing 32 bits float audio fails silently. The doc says 4 bytes is unavailable for AIFF, but I use WAVE. The file is a 5 channels WAVE file with 5 tracks 32bits float at 48kHz. Converting the audio to 16 bits PCM works. Is that a bug ? On vanilla 0.44. Thanks, -- Charles

gemlist into gemframebuffer?
by John Harrison 24 Mar '13

24 Mar '13

I have about 100 spheres I generate with a gemlist which currently display into a gem window. I'd like to instead put them into a gemframebuffer. Is there a way to do this? It seems that gemlist is hardcoded to display in the window? I can think of workarounds i.e. make 100 abstractions of my sphere but that seems clumsy and perhaps inefficient.
