According to the spec [1] MIDIMessageEvent has a data property. MIDIMessageEvent inherits from Event. Event has a target and a timeStamp property [2]. To quote:

"An event object implementing this interface is passed to a MIDIInput's onmidimessage handler when MIDI messages are received. Note that the DOM Event timeStamp attribute is defined as a DOMHighResTimeStamp, and represents the high-resolution time of when the event was received or is to be sent."
