WMD SSF — Chimera

WMD Chimera — Cheat Sheet

Metallic Percussion Synthesizer | Eurorack Module

Control	Function	Notes/Range
DENSITY	Number of grains in the sample window.	Low = slow timbral shifts, High = shimmery, ephemeral bursts.
SURFACE	Morphs between 11 distinct impact surface types.	Captured textures from various real objects.
DECAY	Controls decay time of sounds.	Short = ticks, Long = washed hits.
FEEL	Selects between 3 rhythmic amplitude/volume patterns (see below).	Button toggles mode.
(Pitch) ENVELOPE	Amount of pitch up/down sweep with each note.	Negative = Doppler effect, Positive = Lazer zap.
PITCH	Shifts overall pitch (frequency) of metallic texture.	~5 octave range.
FX	Select between: Bit Quality ↓ ( ), Sample Rate ↓ ( ), Comb Filter ( )	Toggle.
FX AMT	Adjusts depth of selected effect/type.	-
OUT	Main audio output.	Patch to mixer or output module.
TRIG button	Manual trigger when pressed.	Use for manual hits/testing.

Mode 1: All notes equal amplitude—good for consistent hits.
Mode 2: Four-step groove: Normal > Soft > Random > Soft. Added "shaking" from varied attack.
Mode 3: Randomized—each strike unique. With max decay, sounds blend and layer.

Jack	Type	Function	Voltage Range
TRIG	Input	Triggers the sound.	+5V expected for gate/trigger.
ACCENT	Input	Accentuates hit and resets FEEL rhythm.	Typically 0–5V.
CHOKE	Input	Cuts length/amplitude short (mute/stop sound).	0–5V gates.
VCA	Input	Voltage Controlled Amplitude, master volume.	0–5V.
OUT	Output	Main synthesized audio output.	Modular audio, ±5V or ±10V typical.

Most major controls (Density, Surface, Decay, Envelope, Pitch, FX Amt) appear to be CV-able (refer to module for jack locations and labeled CV ins).
Typical CV range: 0–5V, unless marked otherwise. Use attenuators for fine-tuning.
VCA input: Direct voltage control over output amplitude; unaffected by Decay setting.

Use low Density for evolving, spacious metallic textures; high Density for hi-hat, shaker, and noise-burst effects.
Sweep Surface for timbral variety per hit—simulate drums, bells, and abstract percs.
Use Decay to dial from tight, ticked percussion to swirling, cloud-like shimmers.
Explore Feel modes with sequenced triggers to introduce rhythmic interest or randomization.
Pitch Envelope makes for riser/fallers and wild sci-fi percussion.
FX section adds digital or comb character—dial up FX Amt for crush, ring, or shimmer.
