23DSP has released 23HotCold, a free harmonic shaper plugin offering intuitive control over even and odd harmonic distortion. This lightweight version of their MS-23HotCold paid plugin brings professional-level saturation tools to producers at no cost.
Precision Harmonic Control
23HotCold provides two main saturation modes: Hot for adding even harmonics and smooth warmth, and Cold for injecting odd harmonics and aggressive bite. Each mode introduces a unique character, from analog-style saturation to modern, edgy textures. The Drive and Output controls shape the overall impact and final loudness, while Mix lets you blend dry and processed signals.
Smart Features for Creative Sound Design
A standout feature is the Auto Gain, which automatically compensates for volume changes when applying distortion. This makes it easy to dial in the desired amount of harmonics without needing constant level adjustments.
23HotCold is ideal for shaping everything from subtle tonal color to full-on audio destruction, giving producers surgical control over harmonic content in vocals, bass, synths, and more.
System Requirements and Format
23HotCold is available as a free plugin in VST3 format for both macOS and Windows systems.
