[sdiy] analog synths with digital controls? how does that work?

[neil harper]

hey all,
the only modern synth I'm really familiar with is my minitaur, but it
seems that most analog synths these days operate in the same sort of
way. 

so i'm wondering, how are these analog synths able to save/recall
settings and be modified through a computer?

there's gotta be a digital layer between the knobs and the analog parts
of the circuit right? so does that mean that it's sampling the position
of every knob (which i guess it can multiplex) and then using DAC's to
output the required control voltages for all of the knobs (a dac channel
for each knob)? 

what about things that aren't typically voltage controllable, like the
resonance control of a filter..
