More will be written about this feature once its closer to completion. For now, let's just note that it replaces the old 2D panner in Ardour 2.X with code based on VBAP (Vector Base Amplitude Panning). Here's a boring screenshot of the panner:
Lincoln Spiteri did some excellent work adding several new editing features which link into his non-layered mode. The general idea here is a workflow that doesn't rely on crossfades and generally avoids region overlaps. However, these editing operations are useful whether you use this track mode or not.
The latest release of JACK includes a new feature called "JACK Session" which allows the creation of "session manager" applications that can snapshot an entire JACK session, and then restart them en masse at a later time. If you're using Ardour in combination with some external software synth or FX application, JACK Session allows you to store the state of all the JACK applications at once, and then later, restart the exact same setup to continue working smoothly.
Working with a track that has many overdubs can sometimes be a little confusing because its not always entirely clear how the overdubs are all layered with respect to each other. Although there are other methods of moving particular regions to the top of an overlapping set, and although Ardour also has playlists to let you manage takes a bit more efficiently than just continually overdubbing, there are times when being able to clearly see all regions in a track without any overlaps is reassuring and potentially useful.
The information displayed in the track list within the right-hand side notebook of the editor window has been expanded to provide an at-a-glance summary of track/bus status. Because each track takes up just a single line in the list, its possible to display information (and control status) for many more tracks than many be visible in the main part of the editor window.
On the left side of the track list is a set of indicators/buttons that show the following status for each track/bus:
Ardour's ability to import external media files remains essentially unchanged in version 3.0, but thanks to work by Sakari Bergen, an entirely new kind of import is now possible: importing specific material from another session.
Session->Import From Session ..., this process is driven via a dialog that allows to select an existing session file or snapshot (basically any file ending in ".ardour"). It then presents a list of elements that can be imported: Regions, Tracks, Playlists, Locations, and the tempo map.
One long-standing complaint from users in Ardour 2.X was the impossibility of moving track automation data when dragging regions. This behaviour came from a very early assessment of workflow when Ardour was first being developed, and I freely admit that I was wrong about this design.
The Region List in the right hand side tabbed notebook of the editor window has been expanded in Ardour 3.0 to contain a lot more information about each region.
You will note that there are lot of displays of various kinds of time in the expanded region list. The type of time display used here, as elsewhere in Ardour, follows the display mode of the secondary clock. Switch that to "Samples" and all time displays in the region list will switch to the same mode.
Ardour 2.X already had two different recording modes:
- Normal mode: overdubs write to new files, new regions are layered on top of existing regions (with or without crossfades)
- Tape mode: overdubs destructively write to an existing file, single region per track (fixed crossfades at every punch)
There was nothing particularly wrong with the export process in Ardour 2.X, but it did have a few important limitations. The two most significant ones have been fixed in Ardour 3.0: multichannel export (more than 2 channels) and the ability to simultaneously export to multiple formats. This second feature means you can create an compressed and uncompressed version of the same export in a single pass, or DVD and CD compatible formats in a single pass, or all 4 at once, or many other possibilities. Here's the basic version of the new export dialog:
