Well, it's disappointing but I think I can work around it. I'll have to
forego the use of the external sequencer as a slave, but perhaps in
future I'll be able to use it as the timecode master. Meanwhile of
course I can simply save my work in Seq+ as standard MIDI files and use
them in either MusE or Rosegarden. At that point I can simply rely on
JACK for the sync stuff.

Cool. Let me know if there are any specific tests you'd like me to run
with this gear.
