Hi Thomas,
my opinion:

If you have room/funds for only one mixer, get a linear one, as it
will do both audio and cv's more easily than a log mixer imo

A-109 (I own it); think it's a great piece; sound is excellent and
the built-in 2-way mixer & VCA make this a real versatile module

A-113 (own it); have not used it that much, as I found it to require
quite some experimentation to get a useful sound out of it; I am more
easily drawn to oher modules; however I will never sell it; just need
more time to fully explore it
see this link for some sound examples:

A-104 (do not own it); I found the A-127 more versatile in terms of VC
might be a nice module though, but takes up quite some rack-space


Just my opinion

regards
Joost
