U-HE MFM2

What is u-he MFM2 for?

u-he MFM2 is a digital delay plugin designed for modern music production, creative mixing, and sound design. It is used both to place a voice or guitar in space with controlled repetitions and to deconstruct a beat using feedback networks, synchronized modulation, and granular/diffused processing. Ideal as an insert to sculpt a sound or as an auxiliary to build a coherent atmosphere, MFM2 excels in rhythmic textures, atmospheric tails, and stereo movement effects.

Main Features

Input Section: control of behavior before the delay

MFM2 includes 2 input processors to prepare the signal before sending it to the delay lines. The Transient control allows attenuation or accentuation of attacks (useful to prevent a delay from overly amplifying snare hits, or conversely to make a pattern more punchy). The non-resonant input filters serve to clean the bandwidth or to split the spectrum into two stereo bands with independent delay settings (for example, treating lows and highs differently).

4 delay lines: from precise delay to experimental networks

The core of MFM2 is based on 4 delay lines that can operate in tempo-synced mode, free time, or even MIDI note-controlled. The latter approach opens the door to tuned comb filter effects, very effective for transforming pads, creating musical resonances, or making a percussive element "sing." Each line can become part of a complex rhythmic pattern or an evolving atmosphere, depending on the amount of feedback and how you route everything.

Filters and feedback matrix: sculpt, animate, create movement

MFM2 offers resonant filters that you can place at different points in the audio path, with several modes: low pass, high pass, band pass, band reject, and allpass (phaser type). The highlight remains the Feedback Matrix: you choose how each line feeds the others. In simple configuration, you get a clear and controlled delay; in User Matrix, you create cross-feedback loops, custom ping-pong effects, diffusion effects, and quasi-"reverb" behaviors based on very dense echoes.

Pre-feedback effects and dynamics: character and control

Two effect blocks allow processing before the feedback, which radically changes the result: a bit crusher or soft clipper in the loop can produce a delay that degrades with each repetition, while a phaser, frequency shifter, or dedicated filtering can generate rich spectral movements. To finalize, MFM2 includes 2 compressors/limiters (Peak or RMS modes as needed) and can also handle more "mix-ready" behaviors such as ducked or more contained delays. Finally, an output shield (soft clipper) helps tame peaks when loops become very dense.

Modulation and interface: a delay that lives with your track

To maintain a musical and lively output, MFM2 includes 4 synchronizable LFOs (multiple waveforms and user shapes), 2 synchronizable and loopable MSEG envelope generators, as well as a modulation matrix with 4 slots and the possibility to modulate depth via a second source. The interface is resizable from 70% to 200%, improving comfort during sessions. With 400+ presets, you start from ready-to-use atmospheres and then fine-tune according to your mix.
