23HotCold is a free, streamlined version of MS-23HotCold, offering precise control over even and odd harmonic distortion. Whether you're looking to add valve-like warmth or aggressive edge, this plugin gives you essential tools to shape harmonic content with clarity and impact.
🎛 Key Features:
- 🔥 Hot = Even Harmonics: Add rich, musical warmth with asymmetrical saturation.
- ❄️ Cold = Odd Harmonics: Inject punch and bite with symmetrical distortion.
- 🎚 Drive & Output: Push the input, shape the tone, and control final loudness.
- ⚖️ Mix Control: Blend the processed signal with the dry for subtle enhancements or full-on saturation.
- 🤖 Auto Gain: Maintain consistent output levels automatically as you increase the distortion.
From smooth analog-style saturation to more surgical harmonic tweaking, 23HotCold is your go-to harmonic shaper — light, free, and focused.
Beta access on macOS. 23HotCold is in open beta and not notarised by Apple yet — notarisation arrives with the stable release. Until then macOS keeps the quarantine flag it puts on every downloaded file, so there is one short step the first time you install.
Copy the plugin into your Components folder:
/Library/Audio/Plug-Ins/Components/
then run this once in Terminal to clear that flag:
sudo xattr -cr /Library/Audio/Plug-Ins/Components/23HotCold.componentThat is all: macOS then loads it like any other plugin, and Windows needs no setup at all. If your DAW still does not list it, write to hi.23dsp@gmail.com with your macOS version and DAW — beta reports get priority.
23HotCold is free. Downloads and updates come through Gumroad — if it earns a place in your projects, a contribution supports the work.
