MF-101S Lowpass Filter

What it does

A model of the Moogerfooger MF-101 pedal, built around the Moog ladder lowpass filter with resonance, an envelope follower with its own rate control, and a drive stage. The iOS version adds mono and stereo modes and a CV panel on the back, where cutoff, resonance and envelope can be driven by any other Moogerfooger instance, identified by a four letter tag, even across separate tracks or hosts.

In the demo

Jade opens it first of the eight on a sustained chord from a synth in AUM, sweeps cutoff and resonance, then slows the envelope follow rate so the sweep trails behind the notes. She turns the drive up to use it as a distortion, and shows where the built in manual and the preset save slots sit.

Worth knowing

It is one of eight pedals sold separately, and a bundle covering all of them exists on the App Store.
