I will try to give you some detailed feedback later.. but the ardour
implementation of controllers (including learn) as well as MIDI clock sync
operations are fantastic.. sequencing is getting there...
Current CVS version of MusE or the 1.0rc2 version (which I think are the same for
today) are a great show of the sequencing and implementation features..
