+- [tune](https://crates.io/crates/tune) &ndash; a microtonal library
+- [Nannou](https://nannou.cc/) &ndash; a UI framework
+- [FluidLite](https://crates.io/crates/fluidlite) &ndash; a soundfont renderer
 
 It features a virtual piano UI enabling you to play polyphonic microtonal melodies with your touch screen or mouse. The UI provides information about pitches and just intervals in custom tuning systems.
