Simultaneous MIDI notes fail to register

[DBraun]

With Ableton Live and Audio MIDI Setup on my Mac, I'm sending MIDI to IAC Driver.

The MIDI file repeatedly plays two notes at the same time, but the notes fail to trigger "note on" events. When I stagger them just a little bit, the note on messages are successfully printed in this example http://abumarkub.net/jazzmidibridge/example4-channel-program.html

Also, if the end of one MIDI note is exactly the same as the beginning of another, the latter one will fail to register.

Is there something I may be doing wrong?

Edit: https://github.com/cwilso/WebMIDIAPIShim works with simultaneous notes.

Thanks for reporting, this is clearly a bug.

I haven't updated this library for quite a while because I think Chris Wilson's library is a better wrapper; what is the reason you are using JazzMIDIBridge?

I will look into this issue anyway next week as I am adding support for the Jazz plugin to heartbeat

I'm going to use Chris Wilson's library for a personal music visualization project.
