I think I did not grasp the finality of EDL first. In fact, with EDL
everything is computed when you play the song (ie on the fly) and so I
understand the need not to pressure too much the CPU with complicated
operations. I intend, as I said, to make it compute offline and let it play
by another program (sox, ardour, ...)
So I understand that my point is efficiency of complicated (read : slow)
algorithms (say: high level optimization), as your model tend to use EDL
just to "real time cut, paste & loop" of BIG and NUMEROUS channels which
have to be played realtime (I clearly do not make any statements about which
is harder to assume ..). I think my prog (gloop (that's its name)) can NOW
read 24 channels and mix them in a reliable way. but ... maybe not in
realtime.

Thanks, I am wondering : do realtime tweaking of parameters reeally is a
must for you and other people on this list ? Would you bear it if we could
have a "fast" preview and a completely undestructive synth / wave editor or
is it unacceptable ? Is that king of project yet another XYZ or could it be
useful for any one of you ?

Looks cool. But , as you said before in this list, yet another library to
follow development of, take care of building, following API changes,
including in a release ... But really useful for a bunch of us audio
developers.
