WMD SSF — Crater

WMD Crater – Eurorack Cheat Sheet

Category: Hybrid Kick Drum Synth Voice
Size: 8hp
Audio Output Range: 20Vpp
CV Inputs Impedance: 100kΩ

PITCH: Sets kick oscillator pitch (5Hz–100Hz)
SATURATION: Controls boost & saturation before clipping; accepts CV ±5V
CLICK LEVEL: Click volume
CLICK TIMBRE: Selects among 14 click samples, each with noise tail
DECAY: Kick oscillator decay time (affects tail; sustains while TRIGGER is high, decays when released)
CLICK DECAY: Click/noise tail decay time
SUSTAIN: Sets sustain level of oscillator (use gates or sequences for basslines)
PITCH ENVELOPE – AMOUNT: Depth of pitch envelope applied to the oscillator
PITCH ENVELOPE – DECAY: Pitch envelope decay

Jack	Type	Details	Voltage Range / Thresh.
TRIGGER	Gate In	Triggers the kick	2V threshold (Schmitt Trigger)
ACCENT	Gate In	Triggers accent (plug in alone for always-accented)	2V threshold
1V/OCT	CV In (pitch)	Standard pitch tracking (kick FM / melodies)	1V/octave
SATURATION CV	CV In	Modulates saturation (attenuates signal with negative CV)	±5V typical
CLICK LVL CV	CV In	Controls click level remotely	±5V typical
DECAY CV	CV In (kick)	Modulates kick decay time	±5V typical
CLICK DECAY CV	CV In	Click/noise tail decay modulation	±5V typical
SUSTAIN CV	CV In	Modulates sustain level	±5V typical
PITCH ENV DECAY CV	CV In	Modulates pitch envelope decay	±5V typical
PITCH ENV AMOUNT CV	CV In	Modulates pitch envelope amount	±5V typical

Jack	Type	Details	Voltage Range
AUDIO OUT	Audio Out	Main output; kick, click	20Vpp max, 220Ω

LED Display: Shows visual impact of kick
SUSTAIN for Basslines: Hold triggers/gates for sustained 808-style bass; sequence 1V/oct for melodic kicks
Accent Input: Plug in for louder or modified kicks, or use for always-accented hits
CLIPPING Modes: Middle for moderate, right for max/gabber, left for clean
CV Modulation: Most controls have CV inputs (±5V recommended); respond to external envelopes, LFOs, or sequencers
SATURATION Order: Saturation occurs before clipping; use to shape distortion response
CLICK Section: Adjust decay and timbre for punchy or metallic attacks
