Yes---Buzz doesn't show the Note value either. I'm planning to do it
just like that; the only reason it appears in the Octal screenshots is
because that code wasn't finished yet.

Associating a note-type parameter with its associated volume is an
interesting problem. Most likely, the default setting for MIDI maps will
be "note to param n, velocity to param n+1" but it should also be
configurable.

Sort of like the "disappearing" toolbars in Netscape, where clicking
collapses a group of controls? Sounds like a good idea. Also, a notion of
"global parameters" can be added to the API very cleanly.

GTK has toolbar docks that allow people to "tear off" and rearrange
things. I will probably be making use of those at least to play around
with.

I have Octal running on another desktop now. It's just outputting silence,
but I wrote a quickie white noise generator and I'm going to test actual
generation again (this time with GUI.) If that works fine, I will do a
release (with the updated OXAPI developer's guide) this weekend.

Sorry about the long time for this release, I just feel like there's not
much reason to do that until you can actually poke it and get it to make
some sound. :-)
