[PD] audio output AND input with the Rpi?
Hey folks, Apologies as this post is not strictly about Pd, though Pd will be a crucial part of my final setup so whatever solution I find ought to work with Pd. Also, there is a chance the issue might lie with Pd. I just don't know. I'm looking for a usb bus-powered audio interface for the Rpi that can take a stereo input and provide stereo output *at the same time.* * * I have tried a couple different images and a couple different audio interfaces, to no avail. Perhaps there's something can be done with one of these setups to get it working? First, the Pd-LA custom Raspian (v1) image and Pd 43.2: ..with Behringer UCA202 (at 44100khz): Alsamixer picks the device up but the input section shows nothing. Pd (gui) audio preferences allows selection of the interface for both input and output. Output only is lovely and clean but as soon as the device is selected for audio input the audio quality drops horrendously (vaguely recognisable from the original signal).. ..although what gives me hope is I CAN software monitor the input (poorly) in 'Test Audio and MIDI' with this arrangement. ..with Behringer UCA202 (at 48000khz): Output only in Pd is poor (beating and popping sound - possibly sounds like a samp rate conversion issue). When device is selected as Pd input software monitoring is possible and oddly, though the result is still poor, there is effectively no drop in quality from having the device selected only for output and the monitored signal sounds drastically better than at 44100khz. ..with Turtle Beach Amigo II* (at 44100): Alsamixer shows both input and output and allows to change gain of both. If plugged in from boot and only the output is selected in Pd it works but with a lot of jitter. Selecting the device for input too causes a further drop in audio quality although again I can software monitor the input in 'Test Audio and MIDI' If plugged in after boot the OS crashes. The Satellite CCRMA (operating via ssh) and Pd-extended: ..with Behringer UCA202 (at 44100 and 48000): Alsamixer picks the device up but again the input section shows nothing. If I have the device plugged in from boot then I get the same behaviour with it as I do in Pd vanilla on the Pd-LA Raspian image, ie. software input monitoring but at an extremely poor quality. If I don't plug the device in from boot I see it in Pd audio prefs but get this: ALSA input error (snd_pcm_open): No such file or directory ALSA output error (snd_pcm_open): No such file or directory from the Pd terminal and this ALSA lib pcm_hw.c:1401:(_snd_pcm_hw_open) Invalid value for card ALSA lib pcm_hw.c:1401:(_snd_pcm_hw_open) Invalid value for card oops: ALSA cards not reported in order? from the ssh terminal. ..with Turtle Beach Amigo II* (at 44100khz): Alsamixer shows both input and output and allows to change gain of both. If plugged in from boot and then only output selected in Pd I get clean audio out. If I try to select the Turtle Beach as audio inout in Pd then Pd stalls indefinitely when I try to 'Test Audio and MIDI' or make anything in a patch. Same direct input monitoring by default. Also get ALSA input error (snd_pcm_open): Device or resource busy ALSA output error (snd_pcm_open): Device or resource busy from the Pd terminal if I don't have it plugged in from boot, though no message in ssh terminal. *It also appears that by default the Turtle Beach does direct input monitoring of some sorts, the output stage sending out a clean copy of whatever signal is going into the input stage whenever the device is plugged into a usb port. With the Pd-LA image this occurred simultaneously while input monitoring in Pd. I guess this is part of the design of the Turtle Beach, though their documentation is devoid of any useful info regards this. If this is the case then this ain't the sound card for me, though clearly some might find this a very useful feature. Just to give a bit more info about what I'm attempting: I wish to run the stereo input from the Turtle Beach through Pd, play with the audio signal using data from an accelerometer (not nearly there yet) and then send the audio out through the Turtle Beach's stereo output. Apologies for the essay. Hopefully my findings are useful for others and hopefully I can get my rig working! Help muchly appreciated. I've probably left out some crucial bit of info so please shout me if I have! Cheers, Chris Jack.

Re: [PD] flext install (for another amateur)
Hey Thomas, Thanks for getting back to me on this. To be honest I thought I was being a bit stupid so am actually a little relieved that it wasn't *just* me - though of course it is unfortunate that it's not currently working with 0.43.4. I have actually had success compiling it for Pd vanilla 0.44 ...though it refused to put the files in Contents/Resources/extra - as I had instructed it to. However I was able to use it to build the GApop external successfully on first go. Thanks for your time, Chris.

Re: [PD] flext install (for another amateur)
Hi Thomas, Thanks a lot for your help. Seeing as I have not actively installed gcc from any other source I suppose it must be the one from the xcode/developer sdk. Btw, my sdk is 'MacOSX10.6.sdk' - the one appropriate for osx 10.6.8, afaik! My Pd (extended 0.43.4) installation does actually contain the g_canvas.h file in /Applications/Pd-extended.app/Contents/Resources/include/pdextended I have the config-mac-gcc...etc file pointing PDPATH to /Applications/Pd-extended.app/Contents/Resources ...need I point a different variable to Resources/include/pdextended in order to see the header files?

[PD] flext install (for another amateur)
Hey folks, I have been trying in vain to install flext (cvs download) on my 10.6.8 snow leopard Mac.

I have refreshed before each try with a new copy of flext via cvs. Using autoconfig I seem to get this error during build: flutil.cpp: In static member function ‘static void flext_single::CopyMem(void*, const void*, int)’: flutil.cpp:33: error: ‘BlockMoveData’ was not declared in this scope flutil.cpp: In static member function ‘static void flext_single::ZeroMem(void*, int)’: flutil.cpp:44: error: ‘BlockZero’ was not declared in this scope make[1]: *** [libflext_pd_s_a-flutil.o] Error 1 make: *** [install-recursive] Error 1 And using buildsys these errors: Chris-Jacks-Computer-2:flext chrisjack$ bash build.sh pd gcc make -f ./buildsys/gnumake-sub.mak PLATFORM=mac RTSYS=pd COMPILER=gcc BUILDPATH=./buildsys/ PKGINFO=package.txt BUILDCLASS=flext USRCONFIG=config.txt USRMAKE=build/gnumake-mac-gcc.inc TARGETMODE=release TARGETTYPE=single _build_ buildsys/mac/gnumake-gcc-targets.inc:22: warning: overriding commands for target `pd-darwin/release-single' buildsys/mac/gnumake-gcc-targets.inc:18: warning: ignoring old commands for target `pd-darwin/release-single' mkdir -p pd-darwin/release-single mkdir -p pd-darwin/release-single/ g++ -c -DNDEBUG -DFLEXT_EXPORTS -DFLEXT_SYS=2 -DPD -I/Applications/Pd-extended.app/Contents/Resources//src source/flext.h -o pd-darwin/release-single/flext.h.gch touch source/flbase.cpp mkdir -p ./ g++ -c -ffast-math -Os -ftree-vectorize -isysroot /Developer/SDKs/MacOSX10.6.sdk -arch i386 -mmmx -msse -msse2 -msse3 -mtune=prescott -DNDEBUG -DFLEXT_EXPORTS -DFLEXT_SYS=2 -DPD -I pd-darwin/release-single -I/Applications/Pd-extended.app/Contents/Resources//src source/flbase.cpp -o pd-darwin/release-single/flbase.opp_i386 source/flbase.cpp:29:22: error: g_canvas.h: No such file or directory source/flbase.cpp: In static member function ‘static bool flext_obj_single::GetParamSym(t_atom&, const t_symbol*, _glist*)’: source/flbase.cpp:130: error: ‘canvas_realizedollar’ was not declared in this scope source/flbase.cpp:133: error: ‘canvas_realizedollar’ was not declared in this scope make[1]: *** [pd-darwin/release-single/flbase.opp_i386] Error 1 make: *** [build-release-single] Error 2 I am pointing the variables in the txt files to the correct locations, of that I am sure.

[PD] Arduino, Pd and ultrasonics: HELP needed for degree project!
Collin, Pat, thanks for your replies. Collin, I will try the route method in a short while... Pat, that's interesting you use Messenger. I considered it but as I got SMS working quite quickly I've since disregarded it. I will give it a go. Do you mean to apply the identifier at the arduino stage, and if so, what does the code look like? And how does Pd decipher it? I'm sorry, but nothing is obvious to me at this stage - it's all new and I'm trying to make sense of it.
