equivalent specifications. See the Technical Information section on Page 13 for more
information on pedal specifications.
When you plug an expression pedal into one of the pedal inputs on your MF-102, the
pedal adds to the effect of the corresponding control. For example, let’s say that you
plug an expression pedal into your MF-102’s MIX input. With the pedal all the way back,
the mix of direct and ring-modulated sound is set by the MIX knob. Then, when you
advance the pedal, the ring-modulated sound becomes stronger, just as if you turned
the MIX knob up. So, a good rule to follow is: when you use an expression pedal, set the
corresponding knob for the lowest value you want. Then, advancing the pedal
increases that value.
The expression pedal inputs can also be used as control signal inputs. This enables
you to use your MF-102 with virtually any control signal source: modular analog
synthesizers, MIDI-to-CV converters, etc. You will find information on interfacing your MF-
102 with external control signal sources in the Technical Information section on Page
13.
In addition to the four expression pedal inputs, your MF-102 has an LFO output jack, a
CARRIER OUT jack, and a CARRIER IN jack. The LFO and CARRIER OUT jacks may be
used as control or audio signal sources to control other voltage-controlled devices,
including other moogerfooger analog effects modules. The amplitude of the LFO
output signal is independent of the setting of the AMOUNT control or pedal. The
CARRIER IN jack enables you to feed any audio or control signal to the second input of
the ring modulator circuit. When you plug a regular phone plug into the CARRIER IN
jack, the MF-102’s carrier oscillator is disconnected from the ring modulator, and the
signal from the phone plug goes in its place. You can use this feature to ring-modulate
two outputs of your sound module to produce a new, ring-modulated timbre. To do
this, assign a sound (let’s call it “the first sound”) that you want to modulate to one of
your sound module’s outputs, and connect that output to the MF-102’s AUDIO IN jack.
Then assign a second sound to another of your sound module’s outputs, and connect
that output to the MF-102’s CARRIER IN jack. This second sound should be a sustained
sound with a fairly simple waveform. The MF-102’s output will be a completely new
sound, which you can mix with the first sound by turning the MIX control. Try setting the
musical interval between the first and second sounds to an octave, fourth, or third, - or
detune them just a tiny bit. You will be amazed at the variety of new, exciting timbres
that you will be able to create!
