Sidechain & Ducking Reference
BPM-synced sidechain timing diagram showing kick pattern, GR envelope, and bass ducking over one bar with genre presets.
About the Sidechain & Ducking Reference
The Sidechain & Ducking Reference is a free interactive tool for music producers who want accurate answers fast. Whether you're searching for sidechain timing diagram, ducking reference kick bass, sidechain compression genre presets, this tool gives you real-time results without leaving your browser — and explains the reasoning behind every value so you know what to do with it.
Every tool on MusicProductionWiki is built around one principle: answer the question and explain the reasoning. The Sidechain & Ducking Reference not only calculates — it shows you why those values work, what changes when you adjust them, and what professional producers do differently across genres.
This tool is part of the Dynamics & Compression category. It's embedded directly inside the relevant entries in The Producer's Bible — MPW's comprehensive reference library — where it appears in context alongside the theory that explains why each setting works the way it does.
All tools on MusicProductionWiki are free, require no login, and work in any modern browser on desktop or mobile.
Frequently Asked Questions
What is the difference between sidechain compression and volume automation?
Sidechain compression ducks the target automatically and dynamically in response to the trigger signal level — it responds to every kick hit without manual editing. Volume automation is a static, pre-drawn curve that ducks at fixed times. Sidechain is faster to set up and reacts to performance variation; automation gives exact, repeatable control.
How do I stop sidechain pumping from sounding unnatural?
Use a longer attack (5–15ms) so the compressor does not slam immediately, and a release time that matches the tempo — 100–200ms at 128 BPM gives smooth recovery before the next kick. Reducing the ratio from 10:1 to 4:1 also softens the effect. The goal is ducking, not gating.
What is ghost sidechain and when do I use it?
A ghost sidechain uses a MIDI-triggered or manually programmed kick signal to trigger the compressor, even if no real kick is present in the arrangement. This technique is common in hip hop and lo-fi beats where the producer wants rhythmic ducking on pads or bass without a loud kick in the mix.
