I'm able to confirm this.
If I play a virtual JACK MIDI instrument and a virtual ALSA MIDI
instrument, 'in unison' is 'in unison'.
I dunno if there is any measurable latency or jitter, but there's no
audible latency or audible jitter and no visible jitter for audio
recordings of those virtual instruments.

Is this connection through JACK or through ALSA,
i.e., does it show up
in the output of "aconnect -l"? From what I understand, JACK's sample-
synchronous timing always adds latency, and might add period-related
jitter depending on the implementation.
the good stuff adds 1 JACK period of latency to whatever the ALSA
sequencer's direct delivery + the driver does, and zero jitter.
