Why you need an analog lowpass filter

If you're into making music, the Moog Moogerfooger MF-101 is a must-have. Simply put, a lowpass filter removes high frequencies from a sound, rendering it mellower, more muted. The lower you move the cutoff frequency, the more muted your sound. You can think of it like a window shade: as you pull the shade down, it omits the light that's coming in the top of the window, then the light from the middle, and finally all the light. When you sweep the MF-101 Lowpass Filter's Cutoff control, it does the same thing to your sound spectrum. At this juncture, it's worth mentioning that analog is king here; lowpass filters are one area where digital doesn't quite make the grade. Analog lowpass filters sound satisfyingly fat and punchy, and they behave differently from their digital brethren, even allowing you to drive them into self-oscillation with judicious use of their resonance control.

Boatloads of sound-shaping mojo

With its Signal Mix, Cutoff Frequency, Resonance Amount, and Envelope Amount rotary controls, the Moog Moogerfooger MF-101 gives you boatloads of sound-shaping mojo. What's more, you get a choice of 2-pole or 4-pole settings - for brighter or deeper filter frequency response - courtesy of a rocker switch. Another rocker selects between smooth and fast envelope follower response. Want to keep your hands free for playing? The Lowpass Filter's parameters can be controlled with expression pedals or external control voltages (as well as the unit's addictively tweakable knobs).

A bona fide Moog

The MF-101 Lowpass Filter was designed by the legendary Bob Moog. It incorporates a bona fide Moog filter plus an envelope follower for dynamic control over filter sweeps. Use the MF-101 Moogerfooger with keys, guitar, bass, samples, or even recorded tracks, for the ultimate in real-deal analog filter effects, unbesmirched by contact with the digital world! And the MF-101's pedigree? This Moogerfooger is a direct descendant of the original Moog modular synthesizers. Need we say more?

Moog Moogerfooger MF-101 Lowpass Filter Features:

• Cutoff control varies the filter's cutoff frequency over an eight-octave range
• Resonance control varies the shape of the filter's response from pure lowpass to actual oscillation
• Envelope Amount control adjusts amount of input signal envelope sweep on filter cutoff frequency
• Mix control crossfades continuously from unfiltered to filtered audio
• Drive control adjusts the gain of the audio input
• Smooth-Fast rocker switch selects between smooth and fast envelope follower response
• 2-pole/4-pole rocker switch chooses between 2-pole (bright) and 4-pole (deep) filter frequency response
• Level - a 3-color LED used to set the Drive control
• Env - an LED that indicates the strength of the envelope voltage
• Bypass - a 2-color LED that lets you know whether the filter is on or bypassed
• On/Bypass - a rugged, smooth-acting stomp-style actuation switch
