how to develop r_e_c_u_r
i have tried to write this application so it can easily be read and modified for different use cases. i recommend forking the repo to experiment with the codebase. open a pull request into origin <your_branch> if you want to contribute your changes back into the project.
this diagram might help understand the design :

here are some examples of changes you might want to make:
rearranging the keypad controls
to simplify the key-mapping process, i have pre-mapped the numpad keys to the labels a to s like this:

(see dotfiles for description of this process)
for each label the application will read the keypad_action_mapping.json file and map it to an action. the format also allows unique actions per control_mode and per the FUNCTION toggle :
creating a new action
updates in archetecture for v2 :
need to write this :
-explain a bit about using openframeworks as backend , with this repo and this etc, how they communicate - osc etc ...
beyond
i hope the foundations iv provided encourage you to make larger changes for more ambitious features. if so you could try getting in touch (langolierz@gmail.com) first and maybe i could help align your approach with the rest of the project
