Basimilus Iteritas Alia

Noise Engineering

A parameterized digital drum voice with roots in the analog world, built around a six-oscillator additive and FM synthesizer with waveform, harmonic spread, envelope controls, noise oscillator, and wavefolder. Part of the Alia swappable firmware platform.867

Inputs (8)
Attack CVcv0V to 5V867
Decay CVcv0V to 5V867
Fold CVcv0V to 5V867
Harmonic CVcv0V to 5V867
Morph CVcv0V to 5V867
Pitch CVcv-2V to 5V1V/octave pitch CV input with a range of -2V to +5V.867
Spread CVcv0V to 5V867
Triggate≥1.8VGate/trigger input that fires the envelope (no sustain phase). Accepts gates or triggers; can be used at audio rates.867
Outputs (2)
Env Outcv0V to 5VOutputs an envelope signal that tracks the shape of BIA's internal envelope, useful for modulating other modules.867
Outaudio≤14VLow-impedance audio output; level varies significantly with parameterization due to loudness compensation.867

Parameters 10

NameTypeRangeBehavior
AttackknobControls the attack for all oscillators and also shapes the noise character: left of center adds noise, dead center produces an analog-style pop, and right of center slows the attack. Knob offsets the CV input.867
Zones
Noise
Pop
Slow Attack
  • Noise -100–0%Adds noise to the attack; at the leftmost extreme, noise is maximized.867
  • Pop 0–0%At dead center, produces a classic analog-style pop transient.867
  • Slow Attack 0–100%Slows the attack time for all oscillators.867
Bass/Alto/TrebleswitchThree-position switch that shifts the overall pitch of the voice; each position offsets by two octaves.867
DecayknobAdjusts the decay time for all oscillators; knob offsets the CV input.867
FoldknobControls the wavefolder threshold and dynamically adds fold stages for maximum harmonic content. In the top quarter of the range a pulse train is mixed in for additional harmonics. Knob offsets the CV input.867
Zones
Wavefolder
Pulse Train
  • Wavefolder -100–50%Sets the wavefolder threshold; dynamically adds fold stages to maximize harmonic content.867
  • Pulse Train 50–100%A pulse train derived from the signal is mixed in for additional harmonic content.867
HarmonicknobControls harmonic decay and amplitude of the oscillators. Fully left yields a single oscillator tone; increasing blends in additional harmonics with longer decays. Knob offsets the CV input.867
Zones
Single Tone
Two Tones
Full Harmonics
  • Single Tone -100–-100%Only one oscillator is audible; produces a single harmonic tone typical of simple analog bass drums.867
  • Two Tones -100–-50%A second tone fades in alongside the first.867
  • Full Harmonics -50–100%Extends the decays then amplitudes of the remaining four harmonics, adding harmonic richness and longer sustain.867
HitbuttonManually triggers the envelope, equivalent to a gate/trigger at the Trig input.867
MorphknobControls the waveform of all oscillators by continuously blending through sine, triangle, saw, and square. Knob offsets the CV input.867
PitchknobEncoder for adjusting pitch — press and turn for coarse semitone steps, or turn alone for fine tuning. Calibrated for 1V/octave tracking.867
Skin/Liquid/MetalswitchThree-position switch that selects the synthesis algorithm: Skin, Liquid, or Metal.867
SpreadknobControls the frequency spacing between oscillators, sweeping the overtone series from purely harmonic to very inharmonic. Knob offsets the CV input.867
