Doom Engine

Terrarium + Daisy Seed · Mono

Distortion that gets weird. Solid drive core with stackable chaos modifiers — rectify, ring mod, decimator, and resonant filter. Flip all four switches simultaneously for sonic annihilation. The Warp knob controls intensity of all active switch effects in proportion.

Knobs

Knob	Function
KNOB 1	Volume (0× to 2× boost)
KNOB 2	Drive (1× to 150× gain)
KNOB 3	Tone (LP filter)
KNOB 4	Body (pre-drive bass boost — fattens the foundation)
KNOB 5	Warp (master intensity for all engaged switch effects)
KNOB 6	Gate (noise gate)

Switches

Switch	Function
SW1	Rectify (octave-up fuzz character)
SW2	Ring Mod (metallic dissonance, frequency modulated by Warp)
SW3	Decimate (sample-rate crush)
SW4	Resonance (swept bandpass filter — Warp sweeps frequency)

Footswitches

Switch	Action
FS1	Bypass
FS2	Kill switch (momentary signal cut)

Usage tip: Start with Drive (KNOB 2) around noon and Body (KNOB 4) up for a thick foundation, then bring in one switch at a time — Warp (KNOB 5) sets the intensity of every engaged effect at once, so sweep it to dial chaos in proportion. Flip all four switches together and crank Warp for full annihilation; raise Gate (KNOB 6) to tighten the noise between notes. Stab FS2 to chop the signal for stutter rhythms.

WOOF v3 + Daisy Seed · Stereo · MIDI · Expression

All four effects stackable — rectify and ring mod can layer simultaneously (Hothouse's compression goes away). Stereo ring-mod detune for width, plus MIDI and expression. DIPs add stereo flavor and extra grit.

3-Position Toggles

SW1 — Octave & Ring

CenterBoth off. LeftRectify on. RightRing Mod on.

SW1 LEFT and SW1 RIGHT can both be held simultaneously by parking the toggle precisely — but practically, use SW2 for Decimate/Resonance and combine via knob+footswitch routing.

SW2 — Decimate & Resonance

CenterBoth off. LeftDecimate on. RightResonance on.

SW3

Reserved for future expansion.

DIP Switches

DIP 1 — Stereo Ring-Mod Detune

±1.5% L/R spread on the ring modulator frequency. Creates stereo width even with the same dry mono input on both channels.

DIP 2 — Extra Grit

Pushes the asymmetric clipper's positive side 1.3× harder. More even-order harmonics, more aggressive.

Footswitches

Switch	Action
FS1	Bypass (fires on release).
FS2	Kill — momentary signal cut (suppressed during dual-hold gestures).
FS1+FS2	0.5 s hold — Expression Set Mode.
FS1+FS2	2 s hold — clear expression mapping.
FS1+FS2	at power-up — DFU bootloader.

MIDI

Message	Mapping
CC 14–19	Knobs 1–6 (with takeover).
CC 20	Bypass (≥ 64 = bypassed).
CC 21	Kill (≥ 64 = active).

Expression Jack

Defaults to KNOB 5 (Warp) — controls intensity of all switch effects simultaneously. Reassign any knob via FS1+FS2 0.5 s Set Mode.

LEDs

LED 1: Kill active.

Doom Engine

Hothouse + Daisy Seed · Mono · 3-position toggles

Bass-boosted heavy distortion (1× – 150× drive) with four stackable effects controlled by the Warp knob. Hothouse toggles compress the Terrarium's four switches — the rectify + ring-mod simultaneous stack is sacrificed, but each individually still works. Footswitches reversed from Terrarium.

Knobs

Knob	Function	Behavior
KNOB 1	Volume	Output level, 0–2×.
KNOB 2	Drive	Distortion gain, 1× – 150× (drive² × 149 + 1).
KNOB 3	Tone	Post-distortion low-pass filter.
KNOB 4	Body	Pre-distortion bass boost. Adds low-end thickness before the clipper.
KNOB 5	Warp	Master intensity for switch effects: ring mod freq sweep, decimate interval, resonance freq/Q/mix.
KNOB 6	Gate	Noise gate threshold (gate² × 0.8).

3-Position Toggles

TOGGLE 1 — Rectify / Ring Mod (exclusive on Hothouse)

UpRectify on — octave-up fuzz via abs(). MiddleBoth off. DownRing Mod on — Warp-swept ring modulation.

TOGGLE 2 — Decimate

UpSample-rate crush — interval driven by Warp. Middle/DownOff.

TOGGLE 3 — Resonance

UpSwept resonant bandpass (Q 3–15, freq 200 Hz – 3 kHz exponential, mix driven by Warp). Middle/DownOff.

Footswitches (Hothouse convention)

Switch	Action
FS1 (left)	Bypass toggle.
FS2 (right)	Kill switch — momentary signal cut while held.

Usage tip: Set Drive (KNOB 2) around noon with Body (KNOB 4) up for a thick low end, then add one toggle at a time — Warp (KNOB 5) scales the intensity of every active effect simultaneously, so sweep it to balance the chaos. Stack Decimate (TOGGLE 2) and Resonance (TOGGLE 3) over Rectify or Ring Mod (TOGGLE 1) and ride Warp for the heaviest settings; raise Gate (KNOB 6) to tighten the note gaps. Stab FS2 (right) to kill the signal for stutter rhythms.

DFU

Hold FOOTSWITCH_1 for 2 s to enter the bootloader.
