Re: Sequencers

Interesting vision, I like these ideas...  Have some comments.

That makes almost perfect sense.  Hell, you could even write an entire 
object model on that paragraph.
One minor thing though ... not just "sequencers" -- in their classical 
sense -- but more kind of "event propagators", a sequencer being a 
type, piano roll another, et c.

Don't see why the editors should be platform dependant, but anyway...
This idea would seem to be better placed as tieing an editor in with a 
propagator, and having extensions on both for similar types, or 
something like that.

Sorta' like callbacks in ui coding, only not quite, you mean?  A 
"container" sequencer that has an event attached calling another...
Sounds useful.  An event could include 
Using a model like this, we could get into some really great 
event-driven stuff, that can be used to create some really complex 
sounds including live input, even network-run jam sessions (Relatively 
low bandwidth, too) -- other apps too!  .oO(Pressing the accelerator in 
your vehicle sim triggers an event in the octal backend for a truly 
dynamic engine noise).  Of course, that's if we want to take it that 
far...
