Wow, here it is, the first major release of Ardour (1.0 actually never made it out the door before a complete redesign, 2.0, was in the works).  I have personally watched the development of Ardour since the beginning, almost 10 years ago!  Mac and Linux users, enjoy.  Once JACK is available for Windows, MS users can also rejoice.
