Pure Data Set Up – Matthew Olden

Installing Pure Data ….. and other stuff

open a terminal and type these in one at a time, these will update software, install audacity, pure data and some midi stuff

sudo apt-get update

sudo apt-get install midisport-firmware

sudo apt-get install alsa-base alsa-utils

sudo apt-get install aconnectgui

sudo apt-get install audacity

sudo apt-get install puredata

after a while, after pressing yes a few times, everything will be downloaded. If you go to the sound and video section in the menu, you’ll see your new software listed

Installing Pure Data Libraries

Pure Data’s written by a community, so no ones in charge of the all over software. if you can write externals you can get pd to do anything, lots of different people make bits of code that do lots of different things. Its like having photoshop but you can add a word processor to it. You might need an external to do something specific, like look at the karoikie track on a midi file, or one that loads a wierd type of audio file, here with a bit of research you’ll find em. These external librarys all work in PD, but you have to download these seperatley, and store em in a folder. Luckily this is really easy too, Pd has a search engine that looks for these libraries then downloads em and stores em in a folder. After launching Pd go to help and choose find externals.

this brings up the search window. Leave the search field blank and press show all. Then simply double click on the library to install it into Pd

alternativly you can automaticaly install libraries by typing this command in a terminal window

apt-cache search “^pd-“

you’ll get all the available external libraries (which are quite a few). The type

sudo apt-get install pd-libraryname

or this one will download a load of em. Remember tho that different libraries and updates of libraries happens all the time,so some might be unavalible or superceeded.

RJ-DJ the holy of holiest grails

RJ-DJ is a collection of Pd patches that do probably all the sound stuff you have ever wanted to do. It includes effects,midi synths, audio patches, control patches, all sorts of goodies. You need to download it and put it somewhere Pd will find it

got to the website (using the pi’s on board web browser)

https://github.com/rjdj/rjlib

click the green code button and download the zip

this downloads a zip file to the Pi’s downloads folder

double click and it will unzip, choose under extract to the pd folder in documents and into externals

open a finder window then just drag it in, this folder holds all the pd externals you download.

now go to Browser in Pd

and you will see all your new externals listed

after this Pd is ready to go, using it is detailed elsewhere.

Its worth saving all the hard work you have done now by burning off the operating system on a seperate memory card

God Bless CoCo! Ceammc

the ceammc externals are really good. theres loads of great graphic interface objects, and sound objects…looads more too.It can be a bit of a pain to install on the raspberry pi, but thanks to the posts by coco its been solved.

you download two things from here

put em on yer desktop (i downloaded them from the google drive on my mac then transferred them over using VNC)– click the link and scroll down to see how. Double click to install pd-ceammc-2020.07-0.50.1_buster_armv7l.deb

then open a terminal window and type

sudo cp /home/pi/Desktop/libtiny-process-library.so /usr/lib/pd_ceammc/extra/ceammc

we now got to tell pd where this external is, so i add a new path to pds search path

click new and navigate to

/lib/pd_ceammc/extra/ceammc

press save, restart pd and if its worked you’ll be able to open a help file

list of all PD objects

this site here has the thesurus of all pd objects. If you want to find an object that does a specific task, you’ll find it here and information about which library you need.
