When i talk about the UI being hard, i don't only mean the layout,
though that is hard enough. companies like steinberg and sonic foundry
have years of experience doing things like:
* draw a curve over the top of a soundfile amplitude/time graph,
and have the core part of the program scale the volume of the soundfile
accordingly (and change the display). allow the curve to start
with any of 9 different basic curve types, then do bezier-like
spline manipulation on it.
* take an amplitude/time representation of MIDI control data, allow
you to drag every point around, and then apply the new curve
to some aspect of a bunch of audio samples (protools does this
very nicely)
* mouse-click-then-drag-beyond-current-boundary visually stretches
a soundfile display *and* applies timestretch algorithm.
none of these are impossible or even particularly hard with, say, GTK,
but each one of them is a *lot* of work. we don't have a base of
interface details like this to work from; steinberg/sonic
foundry/cakewalk do, and they are using it.
