2012-04-23move MIDI::Manager::cycle_{start,end}() calls from Session into AudioEngine ↵Paul Davis
so that they will continue even if the session has been disconnected from the session git-svn-id: svn://localhost/ardour2/branches/3.0@12066 d708f5d6-7413-0410-9779-e7cbd77b26cf
2012-04-16Fairly major change to the way in which crossfades are handled;Carl Hetherington
they are now done with region fades, rather than separate objects. After this commit, Ardour will try to convert your session files to the new crossfade format, but will make a backup in your session folder first. If you have works in progress using Ardour 3 it is ***STRONGLY RECOMMENDED*** that you back up session files before updating to this commit. git-svn-id: svn://localhost/ardour2/branches/3.0@11986 d708f5d6-7413-0410-9779-e7cbd77b26cf

2012-01-27rework design of midi clock ticker to avoid expensive generalization that ↵Paul Davis

2012-01-05possibly fix deadlocking issues with tempo map by rearranging code and ↵Paul Davis
adding RT variants for a couple of functions that would normally try to rebuild the map when necessary; instead the variants throw an exception and the RT code that called them tries to do something reasonable git-svn-id: svn://localhost/ardour2/branches/3.0@11164 d708f5d6-7413-0410-9779-e7cbd77b26cf
