Note that the odd-numbered lters are sent to the left channel, and
the even-numbered lters are sent to the right channel. This allows
for spreading a sound’s frequencies between two speakers, which
adds a “spacious” feel.
EXPRESSION PEDALS AND VOLTAGE CONTROL
You now know what each of the rotary controls does to the
sound of the MF-105B. The ENVELOPE, MIX, and RATE
controls have expression pedal/control inputs that duplicate their
effects. In addition, the MF-105B has a LFO/SWEEP input which
is used to adjust the speed of the LFO in Bank B patterns, or
to sweep the frequencies of the lters in Bank A patterns. This
enables you to plug in up to four expression pedals to play the MF-
105B with your feet as well as with your hands. The moogerfooger
EP-1 Expression Pedal is designed for this purpose. Or you can use
expression pedals with equivalent specications. See the Technical
Information section on Page 17 for more information on pedal
specications.
When you plug an expression pedal into one of the pedal inputs
on your MF-105B, the pedal adds and subtracts half the range to
the setting of the corresponding control. For example, let’s say that
you plug an expression pedal into your MF-105B’s ENVELOPE
input, with the ENVELOPE control set to 5. With the pedal all
the way in the heel position, the Envelope shape is the same as if
the ENVELOPE control was set to zero. Then, when you advance
the pedal, the Envelope shape begins to morph, just as if you were
turning the knob. At halfway, the pedal equals the setting of the
corresponding control, and at full toe position, it is as if the control
is at 10. A good rule to follow is: when you use an expression
pedal, you set the corresponding knob for the middle value you
want. From the middle of the pedal, advancing to toe position
increases that value, pulling back to heel position decreases the
value.
The expression pedal inputs can also be used as control voltage
inputs. This enables you to use your MF-105B with virtually any
control voltage source: modular analog synthesizers, MIDI-to-
CV converters, etc. You will nd information on interfacing your
