EurekaPROM, EPROM upgrade for the Behringer FCB1010

Will it work with the bias rack processor ?

Using for korg pa1000 arranger keyboard, your eprom helps? sweep pedals can do multiple duty, like control volume of upper 1 and 2 voices?

Is this the eprom revision 3.2, or one of the older ones??

How well will this work connecting a rcb1010 to a rc505?
