[microsound] osc for visual mapping

[Marco Donnarumma]

In my experience this technique has been used for a long time.
Composing an audiovisual concert usually already includes the development of
a protocol to exchange this kind of information between audio and video
processing. Some use MIDI, others use OSC; even though I prefer the latter.

Honestly I find hard to see anything new in this article. Besides, I seem to
understand that's the main point of the author is to establish a "Protocol",
which, as it is described in the article, looks very poor. I agree with
Jeffrey when he refers to this protocol as a semantic layer. It sounds much
more appropriate.
OSC is already a protocol itself. An overlaying structure would perhaps be a
vocabulary to be applied.
It's surely interesting the idea of introducing an editor (external app)
which could automatically add certain metadata to sound pieces, but once we
have to deal with more complex textures, sonorities, and slight, detailed
sound manipulations such protocol wouldn't, in my opinion, be usable.
It could, but only if we carefully compose it. Therefore, a communication
protocol for a complex performance would need in any case more efforts than
a "standard", at least as it is described on CDM.

The appeal of such "protocol" could probably be targeted more to
user-friendly/commercial software users/customers, and a limited musical
field.
Moreover, it's already very easy to setup OSC communication among several
applications, please correct me if someone thinks otherwise.

and, by the way, do we really need a standard for everything we create?

Best,
Marco
