2. MIDI 2.0

Do we accept MIDI 2.0? https://www.midi.org

Accepted with thanks for all review.

Noted future work expected to take advantage of 2-way capabilities

Thanks to Nicholas for important additional reference of interest:

[3] Web MIDI (MIDI Support in Web Browsers)
     https://www.midi.org/17-the-mma/99-web-midi

Impressive excerpt:

> Uses and Advantages
> Here's why the Web-MIDI API for Web browsers is the most significant advancement of MIDI since... MIDI itself!
> 
> Works on all platforms and devices. Anything with a web browser can run a Web-MIDI app and use local MIDI hardware.
> Works with your existing MIDI setup. If your MIDI gear is connected to your computer, tablet or phone (by a cable or even wirelessly) that same connection will connect your MIDI gear to your Web-MIDI enabled browser. 
> Updates are automatic. No need to install new versions, the latest version is always available at the website URL. 
> Accessible anywhere. Apps and data in "the Cloud" are available anywhere you have an internet connection.
> It's the Internet! Browsers make it easy to connect you and your music to other people via social media and on-line MIDI communities.

3. X3D4

Thanos will provide MPEG reference updates.

Descriptions of children approach need further elaboration in the Concepts section, and/or in each abstract node type.

Some nodes do not have children, double check that the entries are all OK.

Can change editorsNote comments about children fields (and large data streams) to proposedDeletion so that they only appear in WD3 and not pristine CD prose.

Final WD3/ballot specification revisions will be applied by Dick and Don.

Efi reports continued steady progress on her modifications to X3DOM and will report if problems occur.

We wondered about FreeWrl (hey Doug), if everything still looks good, particularly because part of how FreeWrl first came about as an audio experimentation platform.

4. The future awaits

We discussed how there are many many opportunities for important progress emerging.  Several big doors are swinging open.  Summary: wow wow wow...

Next week we will discuss how to begin our team's active engagement with W3C Web Audio Working Group.

Much wonderful progress, all positive.  It has been a long road since Efi's original Web3D Conference paper... we did it!  8)

Have fun with X3D4 sound!!

all the best, Don
