yeah sorry frank, i should have explained more clearly.

i also think that no GUI is the way to go for functional abstractions.  that was the big flaw of the DIY library i did, that the function of the abstractions was tied in with the gui component.  i did it that way because i didn't want to clutter the namespace with too many abstractions, and the thought of one abstraction for function, and then a different one for GUI was not appealing at the time.

but now, i think that is the only way to go.  like, as you said, for polyphony.  and then also for the many many cases in which you'd want to build your own gui for custom control.

i do think you guys have got a really really strong system there with rjlib.  but i was just saying that without the gui stuff, it doesn't exactly fit into being that 'all purpose building blocks' library that we are discussing.
