What do you do, type scheme into the Listener? I can't find any
mention of nondestructive editing, or edit decision lists, in the
Snd docs...
In fact I feel like there's a lot more to snd than I can figure out,
in general. I wish there was a comprehensive tutorial. I'd write one
if I understood it better. :)

So if you save an EDL from Snd, you save a text file containing
scheme code?

Sure. Mix and Broadcast support that kind of thing too. In fact I
think envelopes need to be useable for plugin controls too. Once you
can control volume, pan, filtering, and plugins, you have the basis
for a complete virtual studio. I know you're focusing on the
recording end and using your Mackie for mixing & effects, but many
of us don't have much gear. :)

Understood. I do think it's a worthwhile goal, though. I quite like
bcast 2000 except for how often it crashes. :)
OK, how about the ability to use snd-in-ardour to create a new
"track" on "tape"? That would at least allow you to work around lack
of support for "external" files in ardour, at the expense of using
more disk space than accessing the "external" files...
