I remember something like that has been discussed somewhere

Well, if the rectangle on the track editor is made with audio editor,
it is displayed as waveform or as spectogram. If the rectangle on
the track is made with midi editor, it is displayed as matrix.
If the rectangle is made with X editor, it is displayed as X.

When one zooms in to these displays, they might become editable.
(Waveform display usually does.)

Maybe this should be mentioned in this context (before anyone
patents all these ideas): a rectangle may have different
reprentations and thus different display styles. E.g., if the
original data is audio, then the another representation could
be sequence data (midi?) generated with, e.g., wave-to-midi.
When the audio is edited, the other representation is changed
automatically (possibly using lazy-evaluation). If the original
is the sequence, then audio is just renderation of the sequence
(sort of freeze feature).

I wanted to write about this multiple-representations because
in graphics, Silicon Graphics (Wavefront-Alias, Maya) has a patent
on using multiple reprentations. User-friendly for user-editing,
faster for rendering. I invented exactly that basic idea in high
school 10 years before they!

So, if there are further ideas, lets hear them all now before
the ideas are patented.
