Actually, according to the articles you provided, the Mac sound hardware
appears to be a simple fixed-rate DAC that plays back exactly 22,200 bytes per
second, and all of those "modes" are just variations on "calc a buffer and feed
it to the DAC". Knowing that, and how it is programmed, I am now extremely
impressed by Studio Session (it must have mixed 6 digital voices realtime).
I've written "mod" players before but the most I've ever gotten out of 7MHz was
4 voices, and at half that rate. (No doubt the 32-bit registers, and more of
them, are a big help on the mac, but still...)
