The Moog MF-105 is a very unique effect designed by Bob Moog. MuRF is short for Multiple Resonance Filter Array. What this means is the MuRF has 8 filters - their levels are controlled by 8 sliders. It looks like a graphic eq, but the sound of the filters are very different: warm and resonant.
What is really unique is the ability to animate the levels of the 8 filters in up to 24 preset patterns. The rate of the patterns can be set by a knob, expression pedal, or plug a footswitch into the tap tempo input to match the rate to the tempo of your song. Rhythmic variations can be created by adjusting the levels of the filters. The Envelope control sets the shape of the modulation, which can be set for percolating techno rhythmic modulation or shimmering timbral morphing.
MuRF shares the musician-oriented features that are common to all Moogerfoogers. All the audio processing is 100% genuine analog, for warm, fat sound quality. Any line level or instrument level audio signal may be processed. Wide-ranging player parameters may be controlled from the panel knobs as well as from expression pedals or CV-compatible analog synthesis instruments. Components are rugged and long lasting, to withstand the rigors of stage and studio. The MuRF is housed in the classic Moogerfooger "double-wedge" enclosure that may be used on a table or on the floor.
Moog MF-105 main features include:
-
DRIVE Rotary Control: Adjusts the gain of the audio input circuit.
-
OUTPUT Rotary Control: Adjusts the output level when the effect is active. Used for balancing the filtered signal with the bypassed signal.
-
MIX Rotary Control: Sets the proportion of direct to effected signal that appears at the output.
-
PATTERN Rotary Switch: Selects one of 12 Animation Patterns in each bank.
-
BANK Slide Switch: Selects which bank of Patterns is active.
-
RATE Rotary Control: Sets the Rate of the Pattern.
-
ENVELOPE Rotary Control: Sets the envelope shape of the patterns.
-
FILTERS Slider Controls: Controls the gains of the following frequency bands: 200 Hz, 300 Hz, 450 Hz, 675 Hz, 1KHz, 1.5 KHz, 2.2 KHz, 3.4KHz.
-
DRIVE LED: 3-color LED indicates the level of the Input signal.
-
BYPASS LED: 2-color LED indicates effect status.
-
RATE LED: Indicates the Rate of the Animation Pattern.
-
AUDIO IN: Phone jack accepts any instrument-level or line-level signal. Input impedance is 1 megohm.
-
LEFT/MONO OUT: Phone Jack carries the summed signal (left+right, all freq. bands) when Right Output is not connected, and carries the Left output signal (Freq. bands: 200 Hz, 450 Hz, 1 KHz, 2.2 KHz) when the right output is connected. Output impedance is 5,000 Ohms.
-
RIGHT OUT: Phone Jack carries the Right Output signal (Freq. Bands 300 Hz, 675 Hz, 1.5 KHz, 3.4 KHz).
-
RATE, MIX, ENVELOPE, LFO/SWEEP are TRS jacks that accept moogerfooger EP-1 (or equivalent) expression pedals, or control voltages from two or three-circuit jacks.
-
TAP/STEP IN: This tap tempo input accepts a normally open momentary footswitch for syncing the rate of ANIMATION to the tempo of the music.
-
CASE: Steel case with black powder coat finish and wood sides and classic analog appearance.
