This appears to be another issue with chrome://flags/#enable-midi-manager-dynamic-instantiation. MIDI messages emit correctly when this flag is disabled.

Tried the steps mentioned in Comment #2 by enabling the flag enable-midi-manager-dynamic-instantiation and also by disabling it. Can see no issues in both the cases.

Thanks

Let me open this again.

I submitted a patch at r491203, and I assumed the dynamic instantiation mode works even on mac after this patch, but it doesn't?

Ah, sorry. I haven't read the comment#3 and #4.

Let me close again.
