One could try the combination of A-127 and a polarizing mixer A-138c to
emulate an equalizer:

Audio Source -> A-127 Audio In and Input #1 of A-138c
A-127 Audio Out #1 -> Input #2 of A-138c
A-127 Audio Out #2 -> Input #3 of A-138c
A-127 Audio Out #3 -> Input #4 of A-138c

Input #1 of A-138c is used to control the original share of the signal.
Inputs #2...4 are used to add or subtract the filter shares to the original
signal.

From the theory it should work but maybe the phase relations between audio
in and out of the A-127 thwart the plan (with the VC polarizer A-133 even a
voltage controlled version could be realized). Sorry I have no time to try
this out within the next few days (the A-101-9 manual has to be written,
especially the examples have to be tested and written down). If it works we
could think about a revision of the A-127 with polarizers instead of the
normal attenuators (the controls labelled "Audio Level"). Last week we
received new A-100 potentiometer samples with center tap and center click
position for such applications (they work like two separate potentiometer
for left and right half of the rotation angle).
