done two ways, depending on the position of the BANK slider
switch. The switch, located below the PATTERN selector switch is
labeled BANK A or B/LFO. When the slider is in the “A” position,
the lters’ center frequencies can be shifted by an expression pedal
(such as the Moog EP-1) or CV plugged into the LFO/SWEEP
Jack.
To hear how this works, return to the basic setup described in
Figure 5. Plug a Moog EP-1 into the LFO/SWEEP control input.
When the BANK slide switch is in the B/LFO position, an LFO
(Low Frequency Oscillator) shifts the frequencies of the lters as
a group up and down automatically. The LFO is a sine wave. The
rate is determined by the pattern, or an expression pedal (EP-1 or
equivalent) or CV connected to the LFO/SWEEP jack.
To hear the effect of the LFO on the Bass MuRF’s lters, return
to the basic setup outlined in gure 5, then move the BANK slider
switch to “B/LFO”. Now as you play through the Bass MuRF,
you’ll hear the lters swept up and down automatically. To change
the speed of the LFO, plug a Moog EP-1 expression pedal into
the LFO/SWEEP Control Input. The EP-1 can now slow down or
speed up the LFO.

Then, as you play
into the Bass
MuRF, rock the
EP-1 back and
forth. You will
hear the lters’
frequencies shift
with the motion of
the pedal.
