Frohmager
Key Features
- Low-pass resonant filter with harmonic amplification that produces singing, self-oscillating tones unique among filter plugins
- Deep modulation engine with multi-wave LFOs, ADSR envelopes, step sequencer, and envelope follower — all with self-modulation and randomization
- Multi-band filtering mode with width, delay, and count controls to isolate and process specific frequency ranges independently
- Macros-squared system maps any number of parameters to four macro knobs for one-gesture timbral morphing and fast preset exploration
- Built-in distortion before and within the filter for adding grit, warmth, and harmonic saturation
- NKS support for hands-on control with Native Instruments Komplete Kontrol and Maschine hardware
- Preset browser with documented patches including both new presets and legacy Frohmage classics
Description
Frohmager by Ohm Force is a low-pass resonant filter plugin that amplifies harmonic frequencies in a way few other tools can replicate. Originally released in 2001 as Frohmage, it earned cult status among producers for its unique ability to add rich, singing resonance to any audio source.
This updated version keeps the beloved core sound but adds a modulation engine lifted from Ohm Force's Ohmboyz Infinity delay plugin. The modulation grid includes multiple LFO shapes, ADSR envelopes, a step sequencer, and an envelope follower, all with self-modulation and randomization options.
The filter processes audio through a low-pass with cutoff and resonance controls plus built-in distortion. Expanding into multi-band mode lets you isolate specific frequency ranges using width, delay, and count parameters, turning a simple low-pass into a far more flexible sound-shaping tool.
Ohm Force's Macros-squared system maps multiple parameters to four color-coded macro knobs, making it easy to morph between vastly different timbres with a single gesture. This makes Frohmager especially powerful for live performance and real-time sound design.
The plugin supports VST, VST3, AU, and AAX on both macOS (Intel and Apple Silicon native) and Windows, and includes NKS support for Native Instruments hardware integration.

Tips
- Experiment with the modulation matrix to create complex and evolving sounds.
- Use the Macros² system to control multiple parameters simultaneously for dynamic live performances.
- Apply distortion before and within the filter to add character and warmth to your audio.
- Utilize the multi-band filtering options to isolate and manipulate specific frequency bands.
- Explore the preset browser to find inspiration and quickly access a variety of sounds.
- Take advantage of the NKS support for seamless integration with Native Instruments hardware.
- Adjust the tone control to fine-tune the overall sound and achieve the desired sonic texture.
- Use the envelope follower to create rhythmic modulation effects that sync with your audio.
Frequently Asked Questions
How is Frohmager different from the original Frohmage?
Frohmager keeps the same core low-pass resonant filter sound that made Frohmage popular since 2001, but adds a full modulation engine (LFOs, ADSR, step sequencer, envelope follower) from Ohm Force's Ohmboyz Infinity plugin and the Macros-squared macro mapping system. It also adds native Apple Silicon support and VST3 compatibility.
What is the Macros-squared system?
Macros-squared is Ohm Force's advanced macro mapping system that lets you assign multiple parameters to four color-coded knobs with detailed control over each mapping's range and behavior. A single macro can simultaneously adjust cutoff, add modulation, introduce distortion, and more, making it powerful for live performance and preset exploration.
Can Frohmager do more than basic low-pass filtering?
Yes. While the core is a low-pass resonant filter, expanding the band controls (width, delay, count) turns it into a multi-band filter that can isolate and process specific frequency ranges. Combined with the modulation engine and built-in distortion, it can produce everything from subtle sweeps to aggressive, complex sound design textures.
Does Frohmager support Apple Silicon Macs natively?
Yes. Frohmager runs natively on Apple Silicon (M-series) Macs without Rosetta. It supports macOS Monterey through Sequoia and is compatible with Intel Macs as well.
