MS-23HotCold is the extended, Mid/Side-capable edition of 23HotCold, designed for advanced harmonic shaping and stereo field control. With independent Hot (even harmonics) and Cold (odd harmonics) controls for Mid and Side channels, it lets you saturate the core of your mix while sculpting width with precision.
🔥 Hot = Even Harmonics – Warm, smooth, analog-inspired saturation
❄️ Cold = Odd Harmonics – Edgy, focused, and harmonically rich distortion
🔊 Mid/Side Processing – Shape the center and the stereo image independently
⚖️ Global Auto Gain – Maintain consistent loudness across complex settings
🎛 Drive, Output, Mix per Channel – Full control over tonal impact and blend
Whether you're warming up the mids, expanding stereo presence, or enhancing detail in the sides, MS-23HotCold is your surgical harmonic sculptor for stereo masters and individual tracks alike.
💼 Ideal for mastering, buses, synths, and vocals.

Beta access on macOS. MS-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/MS-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.
