neither are recommended. if i had more, a2jmidid's code would already
be a part of JACK, but its not. -X seq and -X raw have *terrible*
timing characteristics and -X seq will even lose data in one or both
directions. a2jmidid, while currently more cumbersome to use, is far
better in every way.

the menu options are for disconnecting and reconnecting to JACK, not
starting and stopping JACK.
starting and stopping JACK while running JACK clients is absolutely
not intended operation. Ardour's provision of these options is mostly
to deal with JACK1's "zombification" design, in which JACK can kick a
client out of the JACK "graph" because of apparent misbehaviour.

templates store everything except actual data.
