I hate to tease people when we haven't released the OS X native version yet, but I sometimes get so tired of people complaining about Ardour not supporting real plugins that I thought this screenshot might be interesting. OS X users - we promise to get this functionality into your hands just as soon as its ready to be used by almost all of you without too many annoying minor issues.
Jonathan Stowe wrote a Perl module to allow remote control of Ardour with Perl via OSC. At present, OSC control is limited to transport and per-track solo/mute/rec-enable operations. Hopefully with this module there to make testing and development of a remote control application easier, OSC control can be expanded in interesting ways.
We are getting closer and closer to being able to release a "native" OS X version of Ardour that will not require X11. There are still several substantive issues to be resolved, but a few bleeding edge users are currently evaluating the initial "All In One" package that includes JACK as well as Ardour (and will very soon include a set of recommended LADSPA plugins too). This has been made possible by the amazing work of the GTK-Quartz porting team, who managed to get GTK to run on a system that is really fundamentally different in several key ways from X11. Stay tuned for more news.
Dave Robillard continues his work on Ardour's MIDI recording, playback and editing capabilities as part of the Google Summer of Code program. Since the last screenshot (below), Dave has added color coding of velocity values, percussion tracks, two modes for delivering MIDI CC data (discrete+interpolated), and some basic editing operations such as quantize, note selection and pencil-based note creation & deletion.
The screenshot below shows some of the progress being made in the trunk branch of Ardour toward MIDI recording, playback and editing. Congratulations and thanks to Dave Robillard, for his rapid work on the core of this as well as the code restructuring it has required, and to Google for funding Dave this summer.
