I disagree. I have 2 Boss SE-50s and the vocoder is not very good. I can't get
anything intelligible out of it.

I know that there are digital systems that are good, like the korg DVP-1 (??) and I
guess this new electrix thing, but Popular opinion seems to side with analog still.
Keyboard magazine, after all, picked the MAM analog vocoder over all the others as
their pick in the "shoot out" a couple months back. I guess I could just get that
one for $300.
