About

MF

This app recreates a classic analog effects pedal, offering an 8-band resonant filter array and an animation module for sequencing filter modulations. It's designed to process and creatively alter audio inputs like guitars, vocals, and synthesizers.

Highlights
  • 8-band resonant filter array
  • Sequenced filter modulation
  • Recreation of classic analog pedal
  • Processes various audio inputs
  • AUv3 effects plug-in

The MF-105S MuRF is a re-invention of Moog Music’s classic Moogerfooger MF-105 analog effects pedal. The MF-105 MuRF (Multiple Resonant Filter Array), originally introduced in 2004, contained two basic functions: an 8-band array of resonant filters that can be voiced for bass or mid frequency response, and a pre-programmed ANIMATION module that generates sequences of envelopes that modulate the levels of the 8 filters. Designed by Bob Moog and his engineering team, the MF-105 was a direct descendant of the original Moog modular synthesizers, adapted to process, modulate, and play with inputs ranging from guitar, voice, and synthesizer to any imaginable audio source. The MF-105 MuRF has been meticulously recreated as the MF-105S, capturing not only the distinctive sound of the original, but also the organic way in which the parameters interact to create a musical playing experience. The MF-105S is an AUv3 effects plug-in that requires a compatible host or DAW to function.

About

Ringotron

This app offers advanced control over ring modulation effects for sound design and audio processing. Its multi-band design allows precise manipulation of the audio spectrum, with a special soft mode to reduce unwanted intermodulation. It can also function as a resonant filter that smoothly transitions into a ring modulator.

Highlights
  • Parallel ring modulator units
  • Stereo separation control
  • Ultra-narrow band resonance
  • Ribbon controls for frequencies
  • Modulation system for band centers
  • Tempo syncing for oscillators
  • Soft limiter and clipper

Ringotron allows taming the strong transformational effects of traditional ring modulation, opening up a wider range of possibilities in sound design and audio FX. Its multi-band design enables fine control over which parts of the spectrum will be transformed by the effect. A special soft mode is available that borrows concepts from feedback modeling, which can be used to reduce intermodulation effects that are often a limiting factor in the more general applicability of ring modulators. In addition to the layers of control they provide, combination of these core features also allows the plugin to act as a stereo, multi-peak resonant filter that can also smoothly morph into a ring modulator. FEATURES: • 2 parallel ring modulator units (max. modulator frequency: 8 kHz) • Stereo separation can be added to band center, mod. frequency, mod. phase • Ultra-narrow bands can be used to create highly resonant sounds • 4 large ribbon controls for band center and modulator frequencies • Band center frequencies can be modulated by the built-in modulation system • Tempo syncing can be independently configured for each oscillator • Built-in soft limiter and clipper to protect against volume spikes IMPORTANT INFORMATION: The plugin comes with a zero-latency, non-brickwall soft limiter, and as such, its stopping power is limited. Make sure to always leave enough headroom or use an external brickwall limiter for total protection against powerful transients. Alternatively, a built-in soft clipper is also available. PLEASE NOTE: • AUv3-compatible host app is required • Suported sampling rates: 44.1, 48, 96 kHz

Verdict

The call

The clearest difference is review sentiment: Ringotron at 100% against MF's 67%. Ringotron also leads on price ($8.99 vs $14.99) and rating (5.0 vs 4.8). MF's advantage is update cadence (monthly vs every 20 months) and iOS requirement (11.0 vs 14.0). On ratings volume, ads, in-app purchases and monetization model there is nothing between them.
