pd-con 2011: CALL FOR SUBMISSIONS
by Moritz Schell 20 Jun '11

20 Jun '11

To all who are interested in composing for the weimar carillon at the pd-con: we collected your questions - answers see below... which are the possibilities of nuances of amplitude of the "porcelain- carillon"? - technically there are no "nuances" for the touch-response: once you played a note the mechanical hammersystem hits the bell with the same intensity. Repeat rate of a single bell / speed of execution of melody? - we just sent a request to the guys who build the carillon if there is any limitation (techically/concerning "health" of the bells). As soon as we have an answer we'll let you know. As far as we tested the carillon with a MIDI-Keyboard there were no limitations except the speed of our fingers :) but the lowest note is sounding rather an a (midi 57) instead of an A (midi 45). - thanks hans for this comment! you seem to be right... The lowest note is an a (midi 57) Is there a full polyphony resp. how many voices can be played simultaneously? - as far as we know there is a full polyphonic response. In principle you can play 35 bells simulaneously... thanks a lot for the nice feedback, keep on questioning if things are not clear and check the Wiki-page, we'll update it frequently. best frederic and moritz Moritz Schell MKG, Master Matrikelnr. 100498 Trierer Straße 42 99423 Weimar 0170 - 851 08 87 moritz.schell(a)uni-weimar.de moritzschell(a)gmx.de

Testing whether a directory is empty without printing error messages if it is
by Matteo Sisti Sette 20 Jun '11

20 Jun '11

Hi, I'm using [folder_list] to perform the following tasks: - check whether a directory or file exists - get the list of files in a directory (which is an empty list if the directory is empty) However, when the file does not exist or the directory of which I'm getting the list is empty, it prints an error message on the console. The test works, but I need to avoid printing error messages when there's no error to worry about. Is there another way of getting a directory list without printing an error message to the console if the list is empty? Thanks m.

numeric order
by Mirko Maier 20 Jun '11

20 Jun '11

hi everybody, i have textfile like 1 this; 4 my; 3 is; 10 file; and i would like to put it into numerical order, so that the final result is 1 this; 3 is; 4 my; 10 list; the only possibility i found was a recursive use of "minmax", but i have huge lists and then it is very cpu-expensive. is there any object for numerical ordering or something shorter than using "minmax"? thanks for hints. best mirko -- NEU: FreePhone - kostenlos mobil telefonieren!

hi list, i found the "pool" object, which presumably can put a textfile into numeric order, but i don't find the way. can anybody help? (in my mailing before, i meant "10 file") best mirko -- Empfehlen Sie GMX DSL Ihren Freunden und Bekannten und wir belohnen Sie mit bis zu 50,- Euro! https://freundschaftswerbung.gmx.de

Re: [PD] pd-con 2011: CALL FOR SUBMISSIONS /weimar carillon
by hans w. koch 19 Jun '11

19 Jun '11

hi moritz, lovely idea! i read this with great interest, as i happen to work on a piece for the tiergarten carillon + electronics in berlin right now. on the website about the carillon you mention the range of the instrument is almost 3 octaves (35 bells). but the lowest note is sounding rather an a (midi 57) instead of an A (midi 45). the soundrecording you provide, actually confirms this. carillons tend to be notated an octave lower, at least the berlin one is, and its lowest bell is g (midi 55), weighting several tons already. i thought i mention, just before someone wants to go all bassy... now i have to convert my max-patch for berlin to pd for weimar :-) cheers hans www.hans-w-koch.net Am 18.06.2011 um 23:28 schrieb pd-list-request(a)iem.at: > Message: 3 > Date: Sat, 18 Jun 2011 15:48:56 +0200 > From: Moritz Schell <moritz.schell(a)uni-weimar.de> > Subject: [PD] pd-con 2011: CALL FOR SUBMISSIONS > To: pd-list(a)iem.at > Message-ID: <A53D99DC-98F6-4F09-8485-600D25653957(a)uni-weimar.de> > Content-Type: text/plain; charset=ISO-8859-1; format=flowed; delsp=yes > > Dear pd-community, > > > you have the chance to rock the bells of weimar city hall! > > During the pd-convention from 8.8-14.8.2011 in weimar there will be > the possibility for "little evening concerts" on the porcelain > carillon in the tower of weimar cityhall.

(OT) is reading files from an NTFS filesystem in linux 30 times slower than ext4?
by Matteo Sisti Sette 18 Jun '11

18 Jun '11

Hi, After a whole day spent trying to find the bottleneck that makes my patche so tremendosly slow to load in Pd under linux, I found out that if I load them from the native linux filesystem (an ext4 partition) they load about 30 times faster than when I load them from my NTFS partition which is where I usually keep all my data. Outside Pd I had never noticed an abnormal slowness in reading data from that disk, and though I did expect NTFS to be slower in linux I am surprised the difference can be so huge. Is it so, or may there be some issue specific to Pd? Thanks m.

Launching puredata -nogui from a terminal
by Matteo Sisti Sette 18 Jun '11

18 Jun '11

Hi, If I launch Pd from a terminal (without "&"), when the terminal is closed Pd dies, which is fine for me. However, if from the terminal I launch Pd with the "-nogui" option, then it survives and keeps running even if the terminal is closed. Is there a way to launch Pd from a script with -nogui in such a way that when the terminal in which it was launched is closed, the Pd process is also killed? Thanks m.
