That is serious coolness.<p>Could you wrap all this code to have something like &lt;audio&gt; tag playing XMs? Having same API&#x2F;events as &lt;audio&gt;? In particular I would like to see playbackRate.<p>I was working on music game and tempo effect was considered. I was wondering at a time if usage of tracker modules would give advantage. Especially ease of changing tempo and maybe automatic conversion of beats to levels.<p>Now is there HTML5 Tracker?
