You can use Legato to make audio effects, synthesizers, samplers, and more.

This was originally going to be a 0.1.0 announcement, but I managed to break the API within a week.

It takes a lot of inspiration from tools like PureData, MaxMSP, VCVRack, and JUCE.

You can create audio graphs with custom nodes and reusable patches and track your graphs with git instead of using a graphical interface.

This lets you easily compose libraries of reusable nodes and functionalities.

Version 0.2.0 changes the ergonomics a bit with custom node creation, which has really improved the DX.
