This is a short demo of Sonant Live – a minimalistic music synth and editor that runs in your web browser.
It has its roots in the demo scene, and was originally a Windows native tool (Sonant by Jake Taylor, aka Ferris / Youth Uprising) for creating songs for 4K demos (where neither the song data nor the music player code can be larger than a couple of thousand bytes at most).
Sonant Live is fully compatible with the original Sonant tool as well as with the js-sonant JavaScript player routine that can be used for adding music to your JavaScript demos.
