[A6] Moog Filter use

[wasubot]

If  you read through the A6 FAQ and such it explains about 24 db in great
detail, from what i understand it is a design issue as mentioned below and
the a6 filter works the same as the original moog one. It can be worked
around (like roland did) but at the expense of loosing that famous moog
resonance sound. Seems like you can either/or but not both, it stated it was
impossible to have both from an engineering perspective.
