<li> John, i know of no event animation chain for X3D that cannot be expressed using X3D4 ROUTE connections using interpolators, sequencers, and event utility nodes. Chasers, dampers, and Script node provides further capabilities for variation. X3D4 architecture appears to have full expressive power for animation.</li>
</ol>
<div dir="ltr">If you want to adapt things in a different way, repeatably, then great - please write a prototype. The X in X3D is Extensible. </div>
<div dir="ltr"> </div>
<div dir="ltr">Of course Script nodes, and programming libraries like X3DJSONLD, X3DJSAIL, x3d.py and others, are both declarative and imperative simultaneously when manipulating the scene graph. </div>

<li dir="ltr"> Doug, we have had great success mapping Web Audio API to X3D4. I think we have a similar path forward to X3D4.1 for MIDI.</li>

<div>Once again, X3D prototypes and Script node can provide a useful path forward for design, implementation, and evaluation of new nodes. <span style="text-align: left; background-color: #ffffff; text-decoration: none; display: inline!important;">Usage of stable prototypes can encourage significant usage and deployment.</span></div>

<div dir="ltr">Given that Web3D Consortium has a formal liaison partnership with W3C, designated Web3D members can further participate in Audio Working Group to share design considerations and suggest refinements in the draft W3C MIDI API. Membership has value!</div>

<div dir="ltr">MIDI nodes are a bit like that - you can design the event sequence / timing in a MIDI authoring tool, then play the .mid file and route from ToneSplitter. I'm thinking about a fireworks scene combining particle physics and midi event sequencing. Perhaps we need something more general, as a utility node set.

No need to fiddle with TimeSensor fields, the SequencerGroup does it for you.
