WMD Cosmic Debris
16-line stereo delay/reverb engine with three modes and live performance controls.
16 HP Eurorack module
Cosmic Debris is a stereo delay and reverb processor built around a network of 16 individually-filtered delay lines, with cross-feedback routing through a 16x16 SCATTER matrix. Three operating modes — BLUR, RATIO, WARP — change how delay lines are arranged and how SPRAY morphs them, ranging from rhythmic stereo delay through lush ambient reverb to pitch-shifted shimmers. Designed by Nick Donaldson of Infrasonic Audio in collaboration with WMD, every control was chosen for live performance: SHIFT-modified secondary parameters, snapshot recall, click-less KILL, latching BLAST/FREEZE/KILL, and slew-limited TIME for sweeping doppler-shift transitions.
Features
- 16 individual delay lines with per-line bandpass filtering
- True stereo input and output (L feeds odd lines, R feeds even lines)
- Three operating modes: BLUR (delay-to-reverb), RATIO (rhythmic stereo), WARP (pitch-shifted shimmer)
- 16x16 SCATTER matrix for evolving cross-feedback textures
- SPRAY control morphs delay-line lengths from rhythmic delays into ambient reverb
- Bipolar feedback with stable 100% (∞) point and gain region (☼) past noon
- ANOMALY adds bit reduction and pitched stutters to the feedback path (lo-fi/glitch)
- FREEZE captures audio buffers indefinitely; bypasses filters and modulation
- BLAST momentary input gain boost with soft saturation, feedback bloom, and 100% send level
- KILL with click-less fade clears all buffers (manual or via gate input)
- Multi-mode GATE jack: FREEZE / BLAST / GLITCH
- SEND mode turns MIX into a CV-controllable send/return level for insert-style use
