23MS-ED Pro - Mid/Side Encoder/Decoder

Take full control of your stereo image with 23MS-ED Pro, a powerful Mid/Side processor designed for mixing and mastering.

With separate processing for the Mid and Side channels, you can:

• Shape Gain independently for a solid center and wide ambience.
• Add Pan Modulation to bring movement and depth to your mix.
• Apply Compression per channel for precise dynamics control.

Whether you want to tighten the low-end, create subtle stereo motion, or push your mix into bold, experimental territory, 23MS-ED Pro gives you the tools to craft a unique sound.

Want to try it out first? Download the free 23MS-ED and explore Mid/Side gain and pan modulation before unlocking the full power of compression in the Pro version.

Beta access on macOS. 23MS-ED pro.component" 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/23MS-ED pro.component"

That 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.
