About osci

​ This version of osci needs *Pd 0.51-4 or above, download Pure Data from: http://msp.ucsd.edu/software.html

​ osci is a library for Pure Data that provides a system for creating oscilloscop music and art.

​ This project is mostly for myself, but I put it on github incase others wished to contribute.

​ I'm a amateur programmer, but I do take suggestions and will make an effort to implement them if I can.

​ This library's repository resides at https://github.com/Eric-Lennartson/pd-osci/.

The documentation is hosted on this repo's Github pages here.

Alternatively, each object has it's own documentation available via pd's help patches.

Downloading osci:

​ You can get osci from https://github.com/Eric-Lennartson/pd-osci/releases - where all releases are available, but osci is also found via Pd's external manager (In Pd, just go for Help => Find Externals and search for 'osci'). In any case, you should download the folder to a place Pd automatically searches for, and the common place is the ~/documents/pd/externals folder.

Some of the abstractions are dependent on objects from the ELSE library. ELSE can be installed either from Pd's external manager or from the command line. ELSE can be found at https://github.com/porres/pd-else.

​ Instructions on how to build osci are provided below.

Building osci for Pd Vanilla:

osci relies on the build system called "pd-lib-builder" by Katja Vetter (check the project in: https://github.com/pure-data/pd-lib-builder). PdLibBuilder tries to find the Pd source directory at several common locations, but when this fails, you have to specify the path yourself using the pdincludepath variable. Example:

make pdincludepath=~/pd-0.51-1/src/  (for Windows/MinGW add 'pdbinpath=~/pd-0.51-1/bin/)

• Installing with pdlibbuilder

Go to the pd-osci folder and use "objectsdir" to set a relative path for your build, something like:

make install objectsdir=../osci-build

Then move it to your preferred install folder for Pd and add it to the path.

Cross compiling is also possible with something like this

make CC=arm-linux-gnueabihf-gcc target.arch=arm7l install objectsdir=../
