DCO=Digital controlled oscilator.
VCO's dont take much, but if you want eight note poly with two osc's 
per voice you're talking 16 of them... DCO's are smaller but aren't 
1v/oct and require a micro processor to drive them.

It essentially applies ALL the VCO's with the same voltage, so in 
effect (if you had 8 note poly with 1 osc per voice) you'd have 8 
osc's playing the same note.

Digital signal processor.... clever little chip, bloody complicated.

the nor modular uses a couple of these... no vco's/vca/vcf nothing its 
all done with a couple of these chips... clever little bugger but 
COMPLEX!!
