Well the 2 digital/wavetable oscs are neither DCOs or VCOs, as those terms
are usually used.  [My definition of the term DCO is "an analogue
wave-shaper running off a digital clock".]

As I recall, the analogue chips in the Evolver were originally designed for
the Marion synth line, and the oscillators were termed "HRO"s -- "High
Resolution Oscillators"; everything I've seen on these has been a bit vague
about what the actually underlying implementation is.  Even DSI's FAQ
dodges the issue by using the term "analogue oscillator waveshapes" rather
than "analogue oscillators" in the answer to the "Is the Evolver analogue
or digital?" question.

Anybody put their Evolver chips under a microscope? :-)

DCOs are allowed to sound warm too... :-)
