midi-in-javascript's Issues

To do: load sf2 files with file API

Well it's easy loading files with the file API, however it would be hard translating those byte arries into sound bank.

See implements in java here:

Events conflict

A comment wrote "Events could be departed via their tick and type. if two events holding the same tick & type, we assume them the same event."

Should it be like that? For instance I might want to note on some a channel for triple times at the same time. All those events might share the same tick & type.

@line 66 in Track.js, the function setEvent.

Tick

TIck in an event should be the dalta time from "The last event", but not from "The start of the Sequence".
