What I&#x27;d love to see is webmidi support, it would be rad to be able to do a windows universal app with es6 and create a midi sequencer for my hardware synths, I can do that on chromeos and then package it as an android app on android 5.0+ but I can&#x27;t do that with windows universal, also can&#x27;t do that with ios. Webaudio is supported across all three but only google and opera so far support webmidi.
