Nice work.

Where to we put things like Elka Synthex? I think it is fair to call its 
oscillators DCOs just like Crumar DS-1 and the like (as I grasp from the 
description) since there you basically have an organ divide down circuit 
per oscillator, but with the twist of having the waveshaping done in 
digital. Modulations still done analog in HF oscillator.

I think we need to be fair and say that there are several classes of 
DCOs. One very popular variant is the reset-control variant.
