Without wanting to seem like a prat, I have to point out a few
realities to your solution.

First, you are correct in saying that the A129 components will do the
job, but that is assuming one has a vocoder (cost: $680 without
shipping).

Then one must purchase 2 more A129/3's ($117 each), and that runs the
price up to $916 (again, without shipping). As I said before, it's
one hell of an expensive way to get individual outputs from the A128.

Then there's the physical differences. The A129's filter types (1
LP, 13 BP, and 1 HP) are different than the A128's 15 BP filters.
Then, the frequencies of the A129 (lowest frequency is 100hZ) are
different than the A128 (lowest frequency is 50hZ).

In short, looking at the cost of the vocoder and additional modules,
I certainly feel modifying my A128 is well worth the time.

Regards,
Kevin
