Floop Chrominator is a free analog-style saturation JSFX plugin for REAPER that adds warmth, harmonic color, and drive to your tracks. Load it directly in REAPER or in other DAWs via YSFX. With five custom saturation modes, oversampling, tilt EQ, filters, auto-gain, and a DPI-aware UI, it’s perfect for mixing, parallel saturation, or creative sound design.
If you have questions, issues, or suggestions, YouTube comments are currently the easiest way for me to collect feedback and improve the script over time.

Floop Chrominator – Frequently Asked Questions (FAQ)
Can I use this REAPER Saturation Plugin in other DAWs?
A: Yes, via the YSFX format, the plugin is compatible outside REAPER.
Does it affect the CPU heavily?
Only HQ Oversampling (4x FIR) is CPU-intensive; standard oversampling is light enough for real-time use.
How do I prevent clicks when changing modes?
Chrominator uses smooth parameter transitions; if clicks appear, reduce extreme drive or oversampling settings.
Does Auto-Gain work on silent tracks?
No, it needs a signal to measure RMS for loudness matching.
Is the plugin fully free?
Yes, Floop Chrominator is completely free.
The project is hosted on GitHub, where the source code and manual installation files are maintained.
