 So -- to stick with the existing terminology before we try to improve

 the messages get split out to parameter destinations based on the
 (probably OSC-style) parameter ID tag?  Is that the idea?


Something like that.  Control IO is the general name for events in and
events out.

I think current Req #57 can be moved into 3.11 with the following
rewording:

    Parameters must be able to receive events from multiple senders. The
    host must handle the...

Insert "...routing and..."?


...merging of events.

I'm not sure what to do with current #58

Recast it as a recommendation to use normalized numbers for continuously variable parameters instead of anything else (perceptual units etc.) where possible? Param-setting msgs intended to drive normalized ranges could be flagged as such in the msg structure; params set up to accept normalized value ranges could be flagged as such in the param description stuff ('metadata' being one possible implementation of same).


(side note - I am unemployed for a couple weeks, so I'll try to have a lot
of free time :)

Treasure that time, it's rare.
