Running status for DIN

[oldgearguy]

I don't think the MRCC will take 'long' MIDI messages and create running status versions.  I think what Darryl and Jesse are saying is that gear that sends running status is handled properly.

Well, that is exactly what it must/should do when message is from USB since the concept of running status does not exist there.

Again,  it's up to the sending thing (hw, sw) to generate running status, not up to any middleman since they have no idea what msg is coming next. 

USB in and of itself does not dictate whether running status is allowed.  The MIDI protocol defines the messaging.  USB is really just a transport mechanism.
