Paul, you're my hero.

I know you've talked about these features, but any idea of
approximately when we might see

1) LADSPA plugin support in snd / ardour?

2) Non-linear editing in snd & ardour? i.e. edit decision lists as
video people call them?
So far I know of only two Linux apps that use EDLs: Mix and
Broadcast 2000. You might want to look at their file formats, if
only to see what you'd like to do different.

An excerpt from a Mix file, with comments added:

# here's a sound clip at time 0.000 in track 1
sound /home/pw/Sounds/drum-like/mouthkick1.wav 0.000 1 1

# here's a sound clip at time 0.357 in track 2
sound /home/pw/Sounds/drumachines/perc/loconga.wav 0.357
2 1

# here's a volume graph for track 3, given as time / value pairs
volumegraph 3
    0.00 60
    5.04 59
    5.18 43
    5.53 43
    5.74 60
  1920.00 60
end

Here's some excerpts from a Broadcast 2000 file:
