yo, re:Verb (or OSCar)

I'm still considering the A6, but there are two or
three deciding factors you might be able to help me
with.

#1. Can you get around the Frames Per Second issue
by using another midi controller for the A6...
I seem to remember hearing that the 808 likes to be
the master and hates being the slave (and is this
any different for the A6?)

#2. How good is the filterbank on the 808? Is it:
OP-1 worth spending the extra 400-500 for the
EX, or
OP-2 worth getting the A6 and putting some of
money on another filter box

which leads to ...is the 808-OP-1 available for the
A6 or compatible? (as the A6-OP-1 is the 808-OP-2)
