Steady State Fate Entity Bass Drum
Deep analog bass drum and percussion synthesizer
14 HP Eurorack module
The Entity Bass Drum is a complete analog bass drum synthesizer built around a resonant filter that creates percussive sine waves when triggered. It features comprehensive voltage control, a 2-stage envelope generator, discrete transistor saturation, and parallel signal processing for creating everything from tight kicks to infinite resonant drones and acid bass lines.
Features
- Temperature compensated pitch tracking
- Discrete transistor saturation
- Parallel signal processing
- Re-triggering envelope
- DUCK output for external VCA control
- RGB LED visual feedback
- All parameters CV controllable
- High fidelity audiophile design
Controls & Jacks (29)
- FM Source — FM routing: FM/FM+ENV/ENV
- TRIGGER — Main trigger input (any signal above 1V)
- FALL — Controls the fall time of the envelope from 1ms to about a minute
- PITCH — Tunes the output frequency from 8Hz to 2.2kHz
- SATURATE — Adds harmonic saturation/distortion to the output signal, from subtle warmth to heavy clipping
- RISE — Controls the rise time of the envelope from 1ms to about a minute
- Output Mode — Output VCA mode: AMP/ENV
- BODY — Simulates drum head tightness, from soft/muted to flabby
- RGB — Visual feedback for trigger, FM depth and output waveform
- 1V/OCT — Pitch tracking input for sequencer/keyboard
- PING! — Trigger button for auditioning without external trigger
- A-MIX — Auxiliary audio input to final VCA stage
- RING — Controls resonant decay time from short/plucky to infinite
- AMP CV — CV input for controlling the output VCA level
- FALL CV — CV input for envelope fall time
- BODY CV — CV input for modulating the Body parameter (drum head tightness)
- Rise Shape — Envelope rise shape: log/lin/exp
- RISE CV — CV input for envelope rise time
- SAT CV — CV input for modulating the Saturate parameter
- ENV OUT — Direct envelope output for triggering or modulating other modules
- OUTPUT — Blends nominal output with secondary input or CV
- Fall Shape — Envelope fall shape: log/lin/exp
- DUCK — Inverted offset envelope output for ducking effects
- FM Input — FM modulation input attenuator. Controls the amount of frequency modulation applied to the bass drum pitch.
- ENV SHAPE — Morphs the envelope shape continuously between exponential, linear, and logarithmic curves
- BASS — Low-frequency EQ input jack for shaping the bottom end of the drum sound
- TREBLE — High-frequency EQ input jack for shaping the top end of the drum sound
- BACK OUT — Secondary output taken before the output VCA, always active regardless of AMP mode
- F-MIX — Direct input to resonant filter
