A general purpose calculator/converter for microtonal/xenharmonic music, built using my microtonal-utils javascript library. Try it out live at yacavone.net/xen-calc.
To get this website working locally (assuming git, curl, and npm are installed), run:
$ git clone https://github.com/m-yac/xen-calc.git
$ cd xen-calc
$ git submodule update --init
$ sh build.sh
then open dist/index.html in a web browser.
