It's funny that information on Apple MIDI programming, which is common to so many music creation apps, is so hard to come by. Of course, I realize it's not generally "hard", and certainly not sexy, so I can see why. But it's not a matter of whether it's easy or difficult, it's a matter of it being explained clearly somewhere so people can learn it. After all, everything is "hard" before you learn it and, generally speaking, "easy" after you learn it! ;-)

James--
Actually, all the remaining chapters were submitted and edited months ago. I have no idea what's going on with the Rough Cut, and I haven't gotten any answers. Sorry for the delays.
We still have some Lion fixes to do on the book code (we used Component Manager to stay Leopard-compatible, and that breaks us on Lion).
I'll be doing CoreMIDI -> AUSampler at VTM:iOS in Boston this weekend, and will have slides on SlideShare and sample code on my dropbox sometime early next week. Maybe that'll help? I also did a MIDI talk for my CocoaHeads in September that I apparently forgot to post to SlideShare; I'll get that up now. I also blogged about writing the MIDI chapter here: <http://www.subfurther.com/blog/2011/09/06/messin-with-midi/>. This was when AUSampler was under NDA, so the demo in that blog handles the MIDI events by playing System Sounds. Secret sauce to get you from a MIDI event to an instrument unit is MusicDeviceMIDIEvent().
Oh man, I wish they'd just update the damn Rough Cut.

That was my concern too: that rather than an outage, the archives are simply being pulled for a business, security, or political reason. For one thing, the mailing lists are publicly searchable, while the devforums are password-protected and covered by NDA. If they do deliberately pull the list archives, our only hope is that they'll copy them over to devforums as archived pseudo-forums. Otherwise, the loss of Core Audio's de facto documentation will set us all back immeasurably.
I would note that bugreport.apple.com has some products that could be appropriate for an "archives unavailable" bug report, perhaps "documentation", "technote / Q&A", or "other".
