David,
I've been "back burnering" the idea of a voltage controlled arpeggiator 
lately, too.
Was thinking something simple using an LM3914 bargraph driver with its 
outputs interfaced to some pots and a CV summer. Might be some 
interesting options available using the 3914 in "dot" mode and "bar" mode.
"dot" mode - each step picks a voltage relative to 0V
"bar" mode - each step "stacks" a voltage on top of the previous step.
