Re: [PD] PInstrument, modular synthesis on Raspberry Pi

Thanks for sharing! Indeed, I find one of Pd's super powers is how flexible it is becoming across devices and environments. > On May 19, 2021, at 12:00 PM, pd-list-request(a)lists.iem.at wrote: > > Using Eurorack has > fundamentally shifted some of my approaches to Pure Data coding and I > wanted to see what I could accomplish here.

numbers seem to be wrongly adding up
by rolfm＠dds.nl 19 May '21

19 May '21

hi, working on a simulation patch i've difficulties with wrong results from additions. in a periodic loop a [value V] is added up with a constant. a simplified version: [t b] - [v V] - [+ 0.0025] - [v V] it starts at 0. looking at the numbers when put in an array i see that e.g. the value that should be 0.1250 is actually 0.1249999 and 0.75 is actually 0.7499994. in the loop this variable is used for calculations which multiply the deviations. why does this simple addition not giving the exact result? rolf

gem video playback performance
by kubriel 18 May '21

18 May '21

hallo, what is the best video codec for Gem? on my linux machines im using mjpeg in mov for long time already, but if there is something better i want to know. because sometimes i use old machines, or very high resolutions. as video decoding in gem is done on per thread basis, sometimes i cut video to four quarters, and play each quarter separately into common framebuffer, so each video has its own thread for my multicore processors. i made also some experiments with gem-mpv and HAP codec, but i had troubles with A/V synchronisation. thanks for hints! k

ekext from Deken is not working
by Julián Villegas 13 May '21

13 May '21

Hi, I’m running into issues when I install ekext from deken. I’m using it for creating an lpc filter, but it crashes every time is start the DSP. However, when I compiled the sources directly, it works as expected. I’m in MacOS 10.15.7, but some students are in Windows and they’re reporting the same issue. I don’t have a Win machine to compile it myself, but I was wondering if someone could take a look at that library in deken and see if it has compiling errors when uploaded… Thanks, Julian.

Mobile music experiment - call for participation
by Gilberto Bernardes 12 May '21

12 May '21

Dear all, On behalf of a Ph.D. candidate at our group, I’m sending the message below inviting you to participate in a mobile music experiment built using libpd! Best wishes, Gilberto Bernardes [Apologies for cross-posting] I am sending this message to invite you to participate in an experiment we are conducting as part of a Ph.D. research on mobile-based digital musical instruments. This experiment is open to participants of any age and background, with the sole restriction being the prototype is currently running exclusively on Android. Participation will require you to install an application on your phone or tablet and run a simple test with wired headphones plugged in - it should take somewhere between 5-10 minutes to complete. If you wish to participate, read the full instructions at https://web.fe.up.pt/~up200005343/instructions.html <https://web.fe.up.pt/~up200005343/instructions.html> If you want to know more about the project, please visit https://web.fe.up.pt/~up200005343/ <https://web.fe.up.pt/~up200005343/>

how to get big numbers from array into a file?
by rolfm＠dds.nl 10 May '21

10 May '21

hi, i'm struggling with the way Pd handles numbers bigger then 999999. i have an array with thousands of numbers, which i write to a file to analyse them. however, as soon as a number is bigger then 999999 i get the abbreviated notation and am loosing the lower digits. in Pd i can make a big number showing all digits by transforming it into a symbol, e.g. with makefilename. but a thus created text-file does not work in a spreadsheet. probably there's a way to overcome this seemingly limitation, but i've not found it yet. anybody with a hint? rolf

kiosk plugin - using only TCL / TK commands? (Linux)
by Ingo 10 May '21

10 May '21

I have a question about the way the kiosk plugin works. Is it using exclusively standard TCL / TK commands that can be sent otherwise on the fly? It looks to me like the kiosk plugin has basically one global setup for Pd all windows (except for the console). I'm asking because I might have changing situations where I want to show a specific window full screen with no task bar but scroll bars and another one maybe as a floating window "always on top" with no taskbar, no scrollbars and not resizable, etc. If this is the case what would be the best way to send these commands from within Pd? [shell] ? [hcs/sys_gui] ? Thanks! Ingo

thanks for the answers. i'm not asking about double-precision here. @Christof [makefilename %d] together with [text] works: in the spreadsheet the 'text' in the output file is seen as numbers. with [makefilename %f] this is not the case. rolf

ignore hidden files from hcs/folder_list
by Samuel Burt 05 May '21

05 May '21

Hi, all. Does anyone have a suggestion to ignore hidden files preceded by a dot? hcs/folder_list outputs all the files matching a wildcard pattern. Seems like there should be some way to look for files that start with a dot and not pass them. I'm loading a directory of audio files but there are a ton of ._files.wav that were created by OSX. I've got a bunch of audio sample directories like this and I could go through and remove all these files, but this software will also be used by someone on a Mac, so it's better to just ignore this inconvenient OS behavior if possible. Thanks! Sam
