RHYTHMIC SIDECHAIN SHAPING
A compact sidechain shaper built for fast, musical ducking with editable curves, synced timing and clear visual feedback.
FATSAW SOFTWARE
FSW Sidechain
FSW Sidechain keeps the entire ducking workflow in one compact surface: define the curve, choose the timing, set the detector and see the gain movement while you work.
01 / CURVE EDITOR
Shape the ducking envelope directly with editable points and curves. Start from a musical preset, refine the contour and use Snap when you want precise timing without slowing the workflow down.
02 / SYNC & DEPTH
Rate follows the host so the sidechain movement stays musical across quarter notes, eighths, sixteenths and faster rhythmic divisions. Amount defines how deep the ducking goes, while Mix lets you blend the processed and dry signals.
03 / DETECTOR
Choose the internal rhythmic trigger for classic pumping or feed an external sidechain source when the groove needs to follow another track. Threshold, Attack and Decay keep the detector focused and intentionally simple.
04 / VISUAL FEEDBACK
A compact real-time display shows how the gain envelope is affecting the signal, giving immediate feedback without turning the interface into a metering dashboard. The goal is fast decisions and clear musical control.
