God point because DSI could just have add a Rc net so the voice boards
did what you suggest, but then would it have sold as well as the DCO
P08 do? In other words, people buy analog shit, as long it contains
the word analog of some sort for 1999.95 euro and Blofelds at 299euro
still sell but only for its price not what it contains or for the
naming digital, still the Blofeld outperforms the P08!

Any VST for 99.95 euro will kick the P08's butt, still it sell, is it
because of the DCO or as DSI put it, *all analog signal chain* that we
now know has control software that dont work properly?

Never underestimate musicians wierd way of reasoning, i still have
to figure out how they come to their conclusions around machines! :-)
