Default Project Requires 6 MIDI controlled pots

I am interested in possibility of making a custom MPA module.

The basic MPA module have 8 digital logic outputs, which i don't
need. The device (parametric EQ) that i would like to automate via MPA
have more than 4 potentiometers with different nominals.

Is it possible to make a custom MPA module to control 6 potentiometers
(3x 10K and 3x 100K) simultaneously?
The easiest way to do this is to chain two MPA units together--one with 10k pots, and one with 100k pots. You can do this by connecting the MIDI Thru on the first unit to the MIDI In on the second.

And another question. What type of taper are digital potentiometers
have? Linear(B), log(A) or anti-log(C)? I` am asking, because my
parametric EQ has anti-log(C) 100K pots and linear(B) 10K pots.
The MPA supports only linear tapers, sorry.

Hope this helps--please let me know if I can provide more information.
