Pallet

An WIP library that makes using the following easier in C++:

• Human interfaces (Mouse, Keyboard, Monome Grid, Midi instruments)
• Midi
• OSC
• Timing
• Graphics
• Audio
• Lua

to make musical and non-musical interfaces easy to develop.

Example use cases include:

• A sequencer using the Monome Grid as an interface
• A window manager macro pad using the Monome Grid or a midi keyboard
• A application that makes tagging images more easier
• An audiovisual application that draws graphics using SDL2 and plays audio using amy
• And all of the above at the same time

Current state

Currently only supports Linux (liblo required), but structured in a way that makes cross platform support easy to support.

A primary goal for this project is to be able to run it on the Raspberry Pi Pico. For this reason, this library primarily relies on static allocation, minimizes its memory footprint, and uses an event queue instead of threads.

Most interfaces (Graphics, Grid, Midi, Osc, Audio, Clock, BeatClock) have been implemented and are functional.

What's left?

• Refactor and revise the APIs for all the interfaces and namespace them appropriately
• Write all the lua bindings
• Ensure proper destruction of resources upon application exit
• Write extensive documentation
• Develop the 'killer app', a sequencer that I have in mind

Why?

• I like C++ and a strong type system
• I want to support multiple scripting languages, especially Guile Scheme
• I love the monome ecosystem and the monome grid as an interface
• I want to explore asynchoronous programming
• I want to make my dream sequencer mostly from scratch for the fun of it
• Eventually, I want to learn the math behind audio processing (filters, mostly) and implement it
• I want to learn embedded programming
