It will set the controller number, but not the min and max.  It's 
possible it's setting it, but the control dialog isn't updating, in the 
latest released version.  I remember fixing that at some point...

Fixed, as usual, in CVS.  The next release will come Real Soon Now(TM) 
(really).

Hmm.  I don't know if that's really possible, since MIDI binding is 
it's own node, and once the output is connected to the input of another 
node, that is the value at that input - period, end of story.

I may go back to the "old" MIDI binding style (somewhat ala AMS)... it 
just isn't good to use in the form it is now, even if it's consistent 
and conceptually elegant.

I think this ties in with what I ultimately want to do with OSC though, 
maybe it will be taken care of by a seperate program.  Like, say, an 
OSC sequencer, or something like it, that sits in between MIDI and OSC. 
 Maybe.

I'll put some thought into this.  It's the general sort of thing at the 
forefront of my mind at the moment..

Hmm.  Good point, I never thought of that.  Input control port values 
are saved, but since the MIDI binding is an output port, it isn't.  
That's kinda a nasty hack.  Hmph.

See previous comment about thinking about it.
