This repository containes the current Web MIDI API standard document, developed by the Audio Working Group at the W3C. There are multiple implementations of the Web MIDI API standard.
Feature requests are welcome, but a quick search in the opened and closed issues is welcome to avoid duplicates.
Pull requests are also welcome, but any change to the standard (barring things like typos and the like) will have to be discussed in an issue (and possibly during a call, accessible only to W3C Audio Working Group members).
