these 3 things can be in conflict. in fact, we have quite a
significant input from users who specifically do NOT want mnemonic
bindings for typical workflows, they want convenient (i.e. one hand on
the mouse, one hand on the keyboard; thus for a right handed mouser,
the common keys are all under the left hand and not mnemonic at all).
this is work style preferred by people who do this sort of thing for a
living; its very awkward and hard to learn by people who dip into this
kind of tool occasionally. which is why we have multiple keybinding
sets and dynamic key bindings.

unfortunately, this is not actually the way that people do this sort
of thing for a living work either. when you have hundreds of things on
the screen, some of them very small, pointing at them in order to
operate on them is inefficient and tedious. for some people, its so
irritating that they even write an entirely new DAW to avoid this
method of working (its called traverso, worth taking a look at for
some interesting, if flawed, UI models). this type of distinction is
most clear when watching people at work on MIDI composition, which is
not an option in the version of Ardour that is currently released. for
the people who actually do this regularly, pointer-driven operation is
incredibly frustrating and incredibly slow. for this kind of work, the
pointer is a fallback position for new users, much like the menus and
so forth in contemporary emacs.

that wasn't my experience when introducing my kids to emacs, nor my wife.

certainly not. but gedit is.

i'm afraid that it does, and i've already pointed you at it. its on
the page labelled "Support" that has a link at the top of every single
web page at ardour.org.

you haven't anything with our project tracking system. what you did
was to show up on an email list, complain that you couldn't get
anything done and then proceed with some sweeping gestures about the
design of a program that exists in a class of software that you
apparently have no prior experience with.

i'm not assuming anything. i'm basing my observations on 10 years of
conflicts between the desires and needs of people who use tools like
this for a living with the desires and needs of people who are just
starting out or just dropping into this kind of tool.

no. it means "the project will be left in the state that it was in its
last saved state". which may have been an explicit save by you, or it
might have been an automatically saved state such as the ones that
occur after every track addition/removal or capture pass. the state is

and the same is true in ardour, except that at present, you can't
autorevert to it from within the program, since it also has an
"autosave" mechanism (this is not hthe same

that is pretty much exactly how an ardour session is organized. there
is only one "index" (the session file) which references objects on
disk which are by and large immutable. the "complete" copy of the
session is the session file plus the objects. a review of 20 years of
DAW development will reveal a history of various approaches to keeping
the "immutable" objects (recorded or imported) audio files in the same
or different locations as the session file. my reading of the general
the general preference (from archived magazine reviews, forums etc.
etc) has been to keep them in the same location. you can snapshot the
session at any time, which simply creates a different version of the
session file, indexing the same objects but possibly with a different
arrangement along the timeline, etc, etc, etc.

i'm struggling to find where i have "not permitted" other people to contribute.

to repeat a question asked by other people: have you ever used any
other DAW before starting to use Ardour?
