According to catalogues there were several different
models. I don't know how many of each version actually were
built, I only know photos of the 1602.

248
   -1602 $ 1,550
   -1606 $ 2,800
   -3206 $ 3,250
   -3210 $ 4,500
   -0004 $ ?

The first two digits describe the number of stages (i.e.
double sliders in the potentiometer section; 2 panel units
per 16 stages), the last two are for the number of sections
labelled "programmed outputs" (1 panel unit per two
sections - the 3210 would be 2,5 racks wide).

There is always one control section (1 panel unit, in which
per-stage-information is determined globally).

The output sections can independently transform the
slider-set main output voltage and time intervals to give
various interpretations of "the sequence" at a time. For
example they contain a voltage controlled time multiplier
(similar to the halftime/ doubletime Sequantizer patch
Grant recently described - MARF sequences from different
output sections can beat against each other's timing); a
descending ramp with a period equal to the interval time
(simplest use: a simple decay envelope whose length always
matches the tempo); controls for various stepping/
stage-addressing modes, etc.

The MARF may be the most capable analog module, but also
the most technically complicated and tedious to use. This
kind of instrument could not but welcome the advance of
digital technology. The software implementations of the
MARF in the Touché/ 400/ 700 systems were more capable and
more convenient to use (having non-volatile memory, higher
time resolution, several available at a time).
