Hello list,

I would prefer to explain here some features we could add, before 
merging them on the UC document. These are just some ideas.

For the UC3 (DAW), for now, I don't see mention of MIDI input/output 
streams. This seems to be important for a lot of us in this mailing list 
to have way to manipulate MIDI events, for virtual synthesizer and other 
cases. We could add more dynamic sound processing out of the box like 
compressor, limiter, deesser, expander.
The deesser could also be added to the UC1.
We could also have pitch-shift and timestrech effects, which are very 
usefull while putting samples together on a specific tempo using a DAW.
For output, as I mentionned before, we could have a way to specify audio 
processing output based on the user device: a 5.1 sound transformation 
for headphones is one of the possible cases (this could be a 
'MediaQueries CSS' like, not based on screen width, but type and number 
of output !).
((One last thing for this UC, which can seem out of the scope of this 
audio working group, but usefull for sharing DAW session, would be the 
possiblity to have a format for these sessions)).

For UC5, we could add support to custom music notation element based on 
font-files ? I think this is a way that Sibelius or others achieve this, 
no ? (Also, browsers are allready able to load custom font in CSS3 with 
@font-face elements).

For UC7 (Vizualisation / Edition / Transformation) we could need sample 
access and modification for this purpose.
