This repository contains all the files and tools needed to build custom oscillators and effects for the prologue synthesizer.

• platform/prologue/ : Prologue specific files, templates and demo projects.
• platform/ext/ : External dependencies and submodules.
• tools/ : Installation location and documentation for tools required to build projects and manipulate built products.
• devboards/ : Information and files related to limited edition development boards.

Note: Make sure git submodules are initialized and updated.

Note: Make sure the necessary toolchain is properly installed. Refer to tools/ for installation instructions.

1. move into a project directory.
2. type make to build the project.

$ make

Packaging to ./waves.prlgunit

Done

3. As the Packaging... line indicates, a .prlgunit file will be generated.

.prlgunit files are simple zip files containing the binary payload for the custom oscillator or effect and a metadata file. They can be loaded onto a prologue (or development board) using the logue-cli utility or the Librarian application (to be released).

Note: The prologue firmware currently does not support the custom oscillator and effects, the feature will be provided in an update planned for June 2018. Currently the feature is only available on the development board

Waves is a morphing wavetable oscillator that uses the wavetables provided by the custom oscillator API. It is a good example of how to use API functions, declare edit menu parameters and use parameter values of various types. See platform/prologue/demos/waves/ for code and details.
