1. Moog Moogerfooger MF-102S RingMod

The MF-102S Ring Modulator is a digital remake of Moog Music’s analog effects pedal, designed for use in modern DAWs. It faithfully reproduces the vintage sound while adding stereo support, multi-instance functionality, CV interconnectivity, and preset management.

1. A Legacy of Modulation

The first MF-102 Ring Modulator was introduced in 1998 and comprised a ring modulator, voltage-controlled carrier oscillator, and dual-waveform low-frequency oscillator (LFO).

I like the warm and vintage sound inspired by the analog hardware, and the rough texture lends life to otherwise sterile tracks. Either subtle effects or something more experimental, it allows for a huge variety of sonic possibilities.

• Intuitive Interface & Controls

For me, the best thing is its simple interface. The controls are well-laid out for easy tweaking of the frequency, LFO rate, and mix. Low-mix is good for adding subtle modulation, while higher settings can make your sound completely different.

• CV Interconnectivity

The unit can modulate other plugins in the collection, creating dynamic, evolving effects across any DAW.

• Presets & Sound Customization

The MF-102S comes with a great preset library to get you started tweaking.

But not every production style will suit it. If your goal is a clean, modern sound, this ring modulation plugin might feel out of place. However, it can still shine with a few tweaks and good mix placement.

2. Numerical Audio RM-1

The RM-1 Wave Modulator audio effect is useful for exploring different modulation techniques—useful for sound designers and musicians looking for unusual textures.

•  4 Modulation Types

The RM-1 I has different modulation types, such as virtual analog and digital ring modulation, amplitude modulation, frequency modulation, and phase modulation.

• Carrier Oscillator 

The RM-1 has a variable wave-shaped carrier oscillator that uses sine and square waves, which is a particular highlight. Such versatility allows for tones from subtle to complex.

• Multimode Filter

A multimode filter (low-pass, high-pass, band-pass), envelope follower, and low-frequency oscillator (LFO) allow dynamic sound shaping.

• Intuitive Interface

Its strength lies in its intuitive user interface as the frequency, modulation depth & filter setting adjustments are all very simple. This way both beginners and experts can use the plugin.

However, the plugin is tied to iOS only and might not work on other platforms. Also, its large modulation range may present some learning curve for new users. Starting with factory presets is good before going into more customization.

Thus, the RM-1 Wave Modulator is very flexible to explore various modulation effects. The variety of modulations, simple interface, and broad connectivity make it an indispensable addition to any iOS-based audio setup.
