The End of Attack and End of Cycle outputs of the Model 10 are designed to be triggering 
pulses so that other EGs could be linked as an overlap (EOA) or after the completion (EOC) 
of the first event.  To that, to meet Doepfer standards they must be a minimum of 5 volts 
high - that's the spec we had to meet.  They are actually a bit  higher than that - about 6 
volts.   To scale them so they would boast a VCO 1 oct, we'd have to limit it to 1 volt high, 
which would not trigger many of the devices they were designed to stimulate.  

My suggestion in your application would be to route the EOA into a scaled input of the 
VCO - one with an attenuator so you could taper it down to whatever level you wish. That 
would work out fine.

hope this helps,

jumps up an octave.  Really makes for an enhanced "whuuuPish" sound.  Now I want to 
send it to other oscillators I have that don't have the same kind of octave switching 
capability.  It seems like I should just be able to attenuate the EOA until it is exactly one 
volt.
