Well, looks like cross-fades are finally solved, at least in terms of a general framework for handling them. This was a big item to finish. The current CVS version is a little unstable when it comes to overdubs and, on SMP systems only, transport-motion thread races. Mixer interface added, with support for track inserts and sends coming, but already supports stereo and surround assignments for tracks. Screenshot coming soon.
Numerous bug fixes.
Many code cleanups, all over the place. 64 bus architecture sort of in place, though currently its not usable via the GUI in any way. Export can be to mono or stereo soundfiles in any format supported by libsndfile. This is still not really correct, in that it covers a wider horizontal area than the waveview windows, and its resolution is wrong. But its a start.
