No complete decoder in each widget. First you create a core object which
encapsulate a decoder, with midibind_new(), then you attach this object to some
widgets with the midibind_attach_...() range of functions. I'm even wondering if
this could not be compatible in some way with the MVC pattern.
I recognize that MVC is very useful to big applications, but it's not so
important for small ones IMHO. Small does not mean limited : thanks JACK, today
we can think about audio applications in the UNIX tradition of connecting
(piping) small apps together. This is the background to 99% of my linux audio ideas.
We misunderstood. I did not mean to be cynical or the like. I posted in here to
get some feedback for my ideas. I _wish_ to be criticized, in a constructive
manner. That's what you did and I do thank you for this, as well as others.
English is not my mother-tongue, and I may not have expressed myself correctly.
Sorry if that's the case. I meant : thanks for your constructive criticism.

Needs checking indeed... Spawning an additionnal
thread may be required.
The reason why I don't "just do it" is because discussing implementations
ideas before coding has been of great benefit to me in the past, especially
here in LAD...
Ok, we'll have multi-threaded widgets. Why ? I can
cache/compare values before asking the widget to update.
How ? If you require say a minimum delta in order to update, it
may never be reached unless it's so small that you will update
for every event anyway. Some form of timeout will be necessary.
Now we have multi-threaded widgets that are also aware of time.
Will you want to create separate threads and timer events for each widget ?
A complete MIDI decoder in each one ? Probably not, so there needs to be
some centralised control. The original idea of making this transparent
is far away at that point. I know what you
mean. But I tend to keep my distances with such
academic considerations.
I've tried this sort of thing on two separate occasions, only to find
out that I had been wasting my time. That's academic, for some value
of that word. Thanks for your input and criticism.
It's not criticism, but since you take it as such, I'll stop here.
Good luck !
