>From the service notes the accent line for each voice has its own 6-bit dac. 
Over midi complete velocity control is possible (great fun running a pattern 
off the 909 and adding to it with another sequencer)

The dac's for each accent line are 4174's all tied into the same data bus, 
with a resistor network on the output...

How about copying what roland have done with this method of accent?
