I am developing a little free software project which is basically a music keyboard and score sheet editor.
My first step in this project is to play note and or conceive notes itself. I use timbre, which is a few documented http://mohayonao.github.io/timbre.js . My first function is to transform for example "C4" (do4 en français) in a audio sound from sine function.
But what I can't do for now is to play and stop notes. Play works for begin the sine wave but when I play a second note, the first note doesn't disappear so I got 2 sine and then 3
