Moogerfooger MF-101 Lowpass Filter

The Moogerfooger MF-101 Lowpass Filter by Moog is an analog effects module designed to work with any sound source. It is a direct descendant of Moog modular synthesizers and offers the following technical specifications:

- CUTOFF: A rotary control that varies the filter's cutoff frequency over a nine-octave range.
- RESONANCE: A rotary control that varies the shape of the filter's response, from pure lowpass to actual oscillation.
- ENVELOPE AMOUNT: A rotary control that adjusts the amount that the input signal's envelope sweeps the filter cutoff frequency.
- MIX: A rotary control that crossfades continuously from unfiltered to filtered audio.
- DRIVE: A rotary control that adjusts the gain of the audio input with a three-color level indicator.
- SMOOTH-FAST: A rocker switch that chooses between smooth and fast envelope follower response.
- 2-POLE 4-POLE: A rocker switch that chooses between 2-pole (bright) and 4-pole (deep) filter frequency response.
- LEVEL: A three-color LED that is used to set the DRIVE control.
- ENV: A LED that indicates the strength of the envelope voltage.
- BYPASS: An on/bypass switch with a two-color indicator.

The MF-101 Lowpass Filter features a 15Hz-12KHz Low Pass filter with resonance, allowing users to select between 12dB/Octave (bright) and 24dB/Octave (deep) filter slopes. It also offers the ability to determine how much the envelope follower modulates the filter cutoff with an envelope strength indicator. Additionally, users can select between smooth and fast envelope follower response and utilize the on/bypass switch with a two-color indicator.

The Moogerfooger MF-101 Lowpass Filter is a versatile analog effects module that provides a wide range of creative possibilities for sculpting and refining unique tones, making it suitable for various applications such as thickening synths, funkifying bass guitars, distorting drum samples, and smoothing out harsh sounds.
