My ever haphazardly-cast interest-of-the-week has settled upon FM-- and the
kind thereof, the DX-7.  Does anyone have or know of a DX-7 architecture
diagram or description?  Among other things, I'm wondering about / hoping
for basic block architecture, the potential oscillator interoperability
(i.e., FM routing), modulation, and EG functionality.

Anyone have any insight as to why greater-than-2-operator FM synthesis never
left Yamaha, aside from Clavia's peek in the Nord Lead 3?  Or are there
synths aside from the DX family and the recent FS1R and DX200 that do
intensive FM?

I are in need of edumacation.  :)  Thanks!
