A few month ago I started to implement exactly that kind of application
(tranzport <-> MIDI). I could achieve much more stability than in the
ardour2 implementation by running an own high priority thread which
immediately puts tranzport-events into a fifo. I will provide the source
code tonight, it is not available here right now.

Having a more reliable tranzport-device with ardour would be great!

Please note that there are also dead-lock bugs in the ardour tranzport
backend. I provided patches for that bug in the mantis pages of ardour
