hmmm - that's a good idea

I seem to have gotten past this to SOME degree - I repatched my midi patch 
bay, and now ardour responds - but sort of spottily - I usually have to make 
several attempts at hitting play on the outside device (a darwin harddisk 
recorder) before ardour responds.  when it responds, it seems to stay in sync 
well for awhile, although what it won't do is pick up from anywhere but the 
beginning - which is the point of using MTC instead of MIDI clock, 
largely...the problem now is it stops after about a minute, but I think this 
is an issue with recording (as that's what I'm doing) and I'm about to test 
to see if it stops when just playing, and to see if when recording while not 
in sync it stops...

the way I understand it, MTC really just IS smpte, translated into the MIDI 
stream so that MIDI devices such as synths and sequencers (and Darwin, and my 
mixer) can deal with it (my mixer has an actual smpte port too I think) 
it's always nice to have 'em all

I have yet to get ardour to really SEND anything.  it's trying to be a slave 
alright, but I was hoping that it would send ADAT sync (that's the other, 
better way to sync darwins is with the adat 9 pin sync card)...it doesn't 
seem to want to receive ADAT sync either - that might have something to do 
with my card, though - I recall seeing something where the ardour guys 
weren't able to get the ADAT sync to work with the Hammerfall cards yet...

I see this option in the options window of ardour - I thought that might be

what would be really great, actually, is if jack could be the centerpiece for 
sync, and for example, ardour, rosegarden AND external devices could sync to 
jack - having a jack be a solid master time code source sending all sync 
codes out at once, with syncing to it just being a matter of connecting up a 
virtual and/or real cable,

as I see people talking, it sounds like ecasound might be a better option in 
some cases for initial tracking... but ecasound has no GUI whatsoever, right?
