MS-23HotCold is the extended edition of 23HotCold, offering Mid/Side processing and deeper control over harmonic shaping. With independent Hot (even harmonics) and Cold (odd harmonics) controls for both Mid and Side channels, it lets you shape the core and the width of your mix with intention and precision.

Key Features:

Hot (Even Harmonics) – Adds smooth, analog-style warmth through asymmetrical saturation.
Cold (Odd Harmonics) – Introduces focused, edgier character via symmetrical distortion.
Mid/Side Processing – Apply harmonic shaping independently to Mid and Side channels.
Drive, Output, Mix per Channel – Control tone, loudness, and blend for each stereo component.
Global Auto Gain – Maintains consistent output level across complex settings.

Whether you're thickening the mids, enhancing stereo depth, or adding detail to the sides, MS-23HotCold is built for precise harmonic work in mastering, group buses, or sound design.

A free version (23HotCold) is available for users who want to explore the core features before upgrading.
