Agenda proposal

Hi all,

I very much enjoyed the last face-to-face meeting, and will be there 
again on April 7th.

I've been making steady conceptual and practical progress with my 
SVG+MIDI project during the past year, and have just uploaded a new 
version of my experimental /Assistant Performer/ to
http://james-ingram-act-two.de/open-source/assistantPerformer/assistantPerformer.html

This version uses a new, more generalized MIDI definition for the event 
symbols, an enhanced speed control, and a new "conducting" mode -- in 
which mechanical time (Javascript's performance.now()) is replaced by 
the live conductor's now(). The relation between what the conductor does 
and how it affects playback is programmable, pointing the way to the use 
of touch-screen gestures and other methods for performing symbolically 
notated scores.

Below is a proposal that I'd like to put on the agenda somehow, but 
first I'd like to thank Daniel Spreadbury, Andrew Hankinson and Craig Sapp:
1. Daniel for his patience during an email exchange last October, in 
which he convinced me that I should separate the container (SVG) and 
MIDI levels more clearly in my mind, and rethink the way I code MIDI 
data inside event symbols.
My applications now use a format that can store/send /any/ MIDI data, 
not just a small subset. And I now realise that the MIDI definition 
could be used in /any/ XML that has event symbols, not just in SVG. For 
example in MNX or MEI.
2. Andrew for pointing me at the Verovio team (I now watch both MEI and 
the Verovio GitHub repository.), and Craig Sapp for an exchange that 
reminded me that the /Assistant Performer/ could quite easily change 
speed at runtime, not just globally. While implementing this capability, 
I realized that I could replace performance.now() completely, thus 
putting the time-control back where it belongs - in the live performer's 
hand and mind.

*A proposal*: My current definition for the temporal meaning of an event 
symbol is quite small and straightforward, and I would like to review 
its details with other programmers interested in this area. That means 
especially those whose software exports SVG. But not only those: I'd 
really welcome input from anyone with expert knowledge of MIDI and/or 
XML. It would be really great if we could arrive at an agreed, 
optimised, standard definition.
I've put the details in a GitHub issue here:

Looking forward to seeing you all again in Frankfurt!
Best wishes,
James
