Pure Data Abstractions

These are Pure Data abstractions - blocks of code meant to be used in a larger patch. They are not necessary at all and patches can be written without them just using Pd-vanilla objects, but these are some common functions that may be useful.

All abstractions can be found in the pure-data-bela-tutorials Github repository, in the folder abstractions.

Additional guidance on how to code using Pure Data on Bela is available in the Bela documentation.

See the Pure Data Examples to see how the abstractions are used in a larger Pure Data patch.


To use these abstractions in Pure Data on your computer, add the path of the abstractions folder to Pure Data through the Pd -> Preferences -> Path... menu. You then will need to quit and restart Pure Data.

To run on a Bela board:

  • either copy the needed abstractions to the local project folder,

  • or scp the abstractions folder to ~/Bela/Projects/pd-externals/;

  • or in the IDE, create a new project called pd-externals and upload the .pd files in the abstractions folder to the project. If a project with that name already exists, just upload the abstractions to that project.
