Crater

WMD

Analog/digital hybrid bass drum module combining 909-style analog tone with digital attack layering. Features pitch envelope, 1V/octave tracking, sustain stage, and digital timbre control.707

Capabilities 2

Kick Drum Voicekick-drum-voice
909-style analog triangle-core oscillator with pitch envelope, amplitude envelope, sustain stage, diode clipping, and digital click/noise attack layer.707
Melodic Bass Voicemelodic-bass-voice
1V/octave pitch tracking and sustain stage enable 808-style bassline sequencing, playing Crater as a melodic sub-bass voice.707

Jacks 4 — 3 in / 1 out

NameSignalVoltageDescription
Inputs (3)
1V/OCTcv1V/octave pitch tracking input for melodic sequencing of the kick oscillator.707
ACCENTgatePlug into ACCENT only to always trigger the accented (louder/hotter) kick.707
TRIGGERgateTriggers the kick drum. When held high (gate), oscillator sustains at sustain level; on gate low, oscillator decays to silence.707

OUTaudio≤20V707

Parameters 9

NameTypeRangeBehavior
AMOUNTknobSets the depth of the pitch envelope applied to the kick oscillator.707
CLICK DECAYknob707
CLICK LEVELknobSets the volume of the digital click/attack layer relative to the analog tone.707
CLICK TIMBREknob1 – 14Selects from 14 sampled click sounds, each paired with a noise tail, for the digital attack layer.707
CLIPPINGknobSymmetric diode clipping circuit. Right position provides maximum distortion by allowing diodes to fully clip.707
DECAYknobSets the amplitude envelope decay time. Oscillator decays to the sustain level while trigger is high, then decays to silence at the same rate when trigger goes low.707
PITCHknob5Hz – 100HzSets the base pitch of the kick oscillator, from 5Hz to 100Hz.707
PITCH DECAYknobControls the decay time of the pitch envelope, ranging from snappy clicks to long disco tom sounds.707
SUSTAINknobSets the sustain level that the kick oscillator holds while the TRIGGER gate is high. Allows gate length to sequence different kick lengths while keeping decay constant.707
