MM2044
Key Features
- Models the SSM2044 circuit stage by stage for the character of a classic 4-pole resonant low-pass filter.
- Uses cutoff, resonance, and drive controls for broad tonal sweeps through to stronger analog-style color.
- Adds a high-pass mode alongside the original-style low-pass response for more flexible sound shaping.
- Lets resonance reach analog-style self-oscillation for pronounced sweeps and effects work.
- Makes the feedback path react to input level, so loud transients can temporarily soften resonance before it returns.
- Runs in VST3, AudioUnit, and CLAP hosts on supported Apple Silicon and Intel Macs.
Description
MM2044 is a component-modeled effect plugin that recreates the SSM2044, the 24 dB/oct resonant low-pass filter associated with instruments including the Korg Polysix, E-mu SP-1200, and PPG Wave. Its signal path is modeled stage by stage rather than as a generic ladder filter, so it is aimed at giving audio the rounded sweeps, driven edge, and self-oscillating behavior associated with that circuit.
The plugin is useful as a character filter on synths, drums, sampled material, and buses when a straightforward cutoff-and-resonance treatment needs more movement than a clean digital filter. Alongside the original-style low-pass response, it adds high-pass operation and drive, allowing it to move from soft tone shaping to stronger resonant effects.
MM2044 also uses the chip's feedback behavior as part of its personality: loud input can temper resonance, then let it return as the source decays. That makes envelope-driven sweeps and transient-heavy material a natural fit, especially where a filter should react with the music rather than remain perfectly static.
The developer supplies MM2044 for macOS in VST3, AudioUnit, and CLAP formats. The download is permanently priced at €0, but the official page asks for a name, email address, and acceptance of its terms before it emails a personal one-hour download link.
Frequently Asked Questions
What hardware filter does MM2044 emulate?
MM2044 is based on the SSM2044, a four-pole low-pass filter chip used in instruments such as the Korg Polysix and Mono/Poly, E-mu SP-12 and SP-1200, and PPG Wave. MM Soundworks says it models the circuit stage by stage from the original schematics.
Does MM2044 only provide a low-pass filter?
No. The original-style 24 dB/oct low-pass response is central to the plugin, but the developer also lists an added high-pass mode and drive control. Those options make it practical for both tonal sculpting and more pronounced filter effects.
Why can the resonance feel different on loud sounds?
The official release notes say that the chip's saturating stages sit in the feedback path. A loud transient can flatten the resonance peak briefly, with the resonance returning as the signal decays.
How do I receive the MM2044 download?
Use the Download button on the MM Soundworks product section, enter your name and email address, and accept the Terms of Use, EULA, and Privacy Policy. The developer then emails a personal download link that remains valid for one hour.
