Hello,

I read so many posts about A-109 that were saying "this module is good for
starters, you get decent filter, VCA, and panner." Well, this is what I
found out: this filter sounds better when used without VCA that is the part
of the same module. Without VCA on A-109, the filter becomes very smooth -
it is a small difference, but possible to hear. And because of that
smoothness, suddenly this filter has a strength/beauty in a mix that was not
present before.

I was just patching some bass sounds (VCO, A-109 filer, and envelope), and
comparing them with ARP Axxe that I own as well. What I like about A-109
filter is a sweet tone, mellow Curtis with very tiny hint of Moog. Still
sounding harder than super smooth and round ARP Axxe (mine has 4075 filter,
one that got replicated in Modcan line of modules).

So, two conclusions: A-109 filter is more than "just decent", it's actually
very good. And by getting the module, you are getting low quality VCA, that
can impact your sound (well, you can always find CV duty for VCA on your
system). I would love to hear if somebody has experience similar (or
completely different, of course) to mine.

Regards,

Zoran
