I'll keep sending the dumps to your e-mail to no bother everyone with garbage. I'll keep digging on what it might be, as i try some code, I think the right way is to see where is the native GTK Port, there should be on ready by know and do it in some widget interface that is very skinnable to make it very beauty to the people's eyes.
I'm really not handy with cocoa interface and even objective C, i'm a Unix code and really don't understand Mac OS X interfaces yet, as i've bought my first Mac only when they come to the X86 arch.
I'm reading a lot of stuff about how the internals in kernel works, as my first self assigned learning job of this architecture is build a driver or just a wrapper to the bcd2000 onboard sound card (its always easiest to understand everything from the beginning for me).
It seems as a highly object oriented architecture so i it might be easy to get how the things work, your machine will be just what i'm needing is my main study will focus on haptic interfaces for sound generation.
See ya

Yes-- in fact, .onChange is redundant:
knob_0.onChange() => now;
is the same as
knob_0 => now;
but either method is fully supported.

You shouldn't need any libs. It looks like there is an error in
makefile.osx... argh. If you delete the '#' character on line 144 of
that file, it should work. 'make osx-ub' doesn't have this same
error, so that will work, but it will produce a universal binary.
So, Ill fix the source distro online also when I get a chance...

OS X has a circular knob user interface widget that we were planning
on supporting. This knob uses the same Objective-C class as the
slider, so if you're handy with Cocoa you could pretty easily switch
the sliders over to knobs.

Yes! the user interface element API definitely needs a lot of
expansion--multisliders, file selection dialogs, menus, text fields,
etc., are all planned, but unfortunately there are only so many hours
in the day... Skinnability would be cool, but I don't think it would
be easy to combine GTK and Cocoa code bases on OS X. Also, GTK on OS
X requires X11, which unfortunately is kind of a second-class citizen
on OS X, and isn't installed by default. It is possible to compile
the wxGTK version of miniAudicle on OS X though--if thats something
that might be a step in the right direction, let me know. Its pretty
easy if you already have GTK and wxGTK.

Hmm, yeah, keep 'em coming! Do you have any idea what kind of actual
MIDI messages the BCD is sending?
thanks!
