This made me have a look at the sources.

Up to ten minutes ago I was believing that a2jmidid used timestamps etc.
to reduce jitter, and that this made it preferable over Jack's -X.

But apparently it doesn't, all events in the same Jack period are
just bunched together. There's even a comment in the source code:

 /* -FIX- this should have the frame time of the event, instead of '0': */

So what is the advantage ?
