And how would you like to do this? Italics, size, colors, different font? It seems that [list] classes (e.g. [list split]) turn words into symbols and multiple words into a list automatically, just as numbers are turned into floats and multiple numbers into a list everywhere in Pd. The confusion is not that people cannot remember the words float, list, bang, symbol to be reserved, but that they are used to the convenience of how Pd handles floats and list of floats. You would almost forget that "dog" is not a symbol and that "dog cat bear" is not a list, particularly because [list split] doesn't complain and just returns a real list. --Funs

Re: [PD] ALSA MIDI problem
by Dan Wilcox 21 Jan '14

21 Jan '14

Here's a portion of a startup script I use: ------------------------ echo "rc_starts_pd: strating pd" pd -rt -nogui -alsa -audiodev 4 -audiobuf 10 -alsamidi $PATCH & # renice pd for much higher priority renice -10 $(pidof pd) # wait for pd to initialize KA=$(aconnect -i -o | grep "Pure Data") while [ "$KA" = "" ] do sleep 1 echo "rc_starts_pd: pd alsamidi not ready" KA=$(aconnect -i -o | grep "Pure Data") done echo "rc_starts_pd: pd alsmidi is ready" # connect the UA-25 midi to Pure Data echo "rc_starts_pd: alsa midi connect 'UA-25' <-> 'Pure Data'" aconnect 'UA-25' 'Pure Data' aconnect 'Pure Data':1 'UA-25':0 # connect the VIEWCON dongle midi to Pure Data echo "rc_starts_pd: alsa midi connect 'VIEWCON..' <-> 'Pure Data'" aconnect 'VIEWCON..' 'Pure Data' aconnect 'Pure Data':1 'VIEWCON..':0 ---------------------- It starts Pd, then waits until the PD midi device is registered with ALSA before trying to connect two Midi devices: UA-25 & VIEWCON.. You could run the script from you ~/.bash_profile which would call it as soon as the user is logged in. I use this: --------------------- # do nothing if this is a ssh session if [ "$SSH_CLIENT" != "" ] ; then exit fi rc_starts_pd --------------------- It's important to ignore ssh sessions since, if you're like me, and you want to login to your (wearable) computer via SSH to check something, you don't want to launch a new instance of pd.

ALSA MIDI problem
by Jack 21 Jan '14

21 Jan '14

Hello, I need your help :) I try to use my M-Audio Uno MIDI interface with Pd, but it doesn't work. I tried this three command to be sure that my MIDI interface works. $ lsusb ... Bus 001 Device 007: ID 0763:0150 Midiman M-Audio Uno ... $ dmesg | tail [ 389.178324] usb 1-1.2: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [ 389.178328] usb 1-1.2: Product: USB Uno MIDI Interface [ 389.178331] usb 1-1.2: Manufacturer: M-Audio $ amidi -p hw:1 -S 'F0 43 10 4C 00 00 7E 00 F7' and i can see the LED "MIDI out" blinking. Now with Pd, i tried : $ pd -nosleep -noaudio -alsamidi -midiindev 0 -midioutdev 0 or $ pd -nosleep -noaudio -alsamidi -midiindev 1 -midioutdev 1 but after checking the toggle "MIDI OUT" in "media -> test Audio and MIDI", and can't see LED blinking on my interface. Even after "media -> ALSA MIDI" : In Ports : 1, Out Ports : 1 -> Apply and OK, I get nothing. I am sure i miss something... Any help is welcome. Thanx. ++ Jack

problem with sort object
by D G 21 Jan '14

21 Jan '14

Hello i need a list sorting object and there is [sort] in the zexy externals. but it seems that i have found a bug. if I use the following list of unsorted numbers 0.192477 0.00670372 *0.152811* 0.00688959 0.162687 0.00633917 0.188098 0.00716823 0.177974 0.00697544 0.159727 0.00695443 0.166196 0.00645065 0.168316 0.030957 i get this sorted list in return 0.00633917 0.00645065 0.00670372 0.00688959 0.00695443 0.00697544 0.00716823 *0.152811* 0.030957 0.159727 0.162687 0.166196 0.168316 0.177974 0.188098 0.192477 this number in bold font (the third one from the unsorted list) is not correctly sorted it happens with this other list too: unsorted: 11.6279 0.129769 *3.50877* 0.396668 15.873 0.16442 5.26316 0.397614 16.9492 0.16818 3.57143 0.3367 10.4167 0.15758 4.14938 0.19972 sorted: 0.129769 0.15758 0.16442 0.16818 0.19972 0.3367 0.396668 *3.50877* 0.397614 3.57143 4.14938 5.26316 10.4167 11.6279 15.873 16.9492 and the problem seems to be of the object in the third position. Does this make any sense to anybody? can you replicate the error with the same numbers? is there another object to sort the elements of a list or an array? thanks Daniel

Compiling Pd in Sabayon
by Alexandros Drymonitis 20 Jan '14

20 Jan '14

Having had some problems with audio drop outs in Ubuntu, I am now giving Sabayon 14.01 a try. I'm trying to compile Pd, ./autogen.sh seemed to work fine, but when I type ./configure --enable-jack things go wrong. At the end of configure I get these messages: ./configure: line 15417: syntax error near unexpected token `JACK,' ./configure: line 15417: ` PKG_CHECK_MODULES(JACK, jack, have_jack=yes, have_jack=no)' configure: error: ./configure failed for portaudio I checked line 15417 in configure, but doesn't make any sense to me, unfortunately.. plus some other stuff that don't seem write (out of intuition, not knowledge or experience) for example: checking machine/soundcard.h usability... no checking machine/soundcard.h presence... no checking for machine/soundcard.h... no checking for _oss_ioctl in -lossaudio... no I also got lots of warnings when I typed make, like: msgfmt --check --tcl --locale=af -d . af.po af.po:6: warning: header field 'Language' missing in header Don't know if this helps, the messages from configure are quite a lot, I could post them if it's more helpful. I have Jack1 installed (there might be some issues there with memory allocation, but that should go to Jack's list, don't know if this influences Pd's compilation) and ALSA. I've been posting a lot on this Linux and Pd issue of mine lately, but I do wanna give this combination a try...sorry if I irritate anyone..

signal math explanation
by Pall Thayer 18 Jan '14

18 Jan '14

Can anyone tell me what one is accomplishing when doing something like this: [osc~ 440] | [+~] |\ [+~] |\ [+~] |\ [+~] In other words, the chain of [+~] that feed the previous object's output into both inlets of the next... what does this do exactly? Thanks, Pall -- ***************************** Pall Thayer artist http://pallthayer.dyndns.org *****************************

Re: [PD] rc-unitd, was pd gui: partial interface freeze
by Dan Wilcox 18 Jan '14

18 Jan '14

This may be related: Years ago, I wrote a separate app daemon which grabs hid joystick events and streams them over OSC into pd. This approach works very well, even on low resource machines or when you want to separate audio & control machines. For my upcoming show, I'm using an RPi + Bluetooth to stream physically hacked PS3 controller-based input devices into PdParty running on an iPad. See https://github.com/danomatika/rc-unitd I use it on Linux & OSX. Probably works on Win but haven't tried it.

[netsend](tcp) is much faster than [udpsend] why??
by Jonghyun Kim 18 Jan '14

18 Jan '14

Hi list, I found this result that [netsend] (tcp) is much faster than [udsend]. It tested on between Mac and Ubuntu connected within eth0. I don't know why udpsend is much slower than netsend. Normally tcp is slower than udp, but netsend with tcp is faster than udpsend. It's strange. Who know it, why it causes? Thanks, Jong
