Basimilus Iteritas Alia
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

Jacks 10 (8 in / 2 out)
| Name | Signal | Voltage | Description |
|---|---|---|---|
| Inputs (8) | |||
| Attack CV | cv | 0V to 5V | 867 |
| Decay CV | cv | 0V to 5V | 867 |
| Fold CV | cv | 0V to 5V | 867 |
| Harmonic CV | cv | 0V to 5V | 867 |
| Morph CV | cv | 0V to 5V | 867 |
| Pitch CV | cv | -2V to 5V | 1V/octave pitch CV input with a range of -2V to +5V.867 |
| Spread CV | cv | 0V to 5V | 867 |
| Trig | gate | ≥1.8V | Gate/trigger input that fires the envelope (no sustain phase). Accepts gates or triggers; can be used at audio rates.867 |
| Outputs (2) | |||
| Env Out | cv | 0V to 5V | Outputs an envelope signal that tracks the shape of BIA's internal envelope, useful for modulating other modules.867 |
| Out | audio | ≤14V | Low-impedance audio output; level varies significantly with parameterization due to loudness compensation.867 |
Parameters 10
| Name | Type | Range | Behavior |
|---|---|---|---|
| Attack | knob | — | Controls 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 |
| Bass/Alto/Treble | switch | — | Three-position switch that shifts the overall pitch of the voice; each position offsets by two octaves.867 |
| Decay | knob | — | Adjusts the decay time for all oscillators; knob offsets the CV input.867 |
| Fold | knob | — | Controls 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 |
| Harmonic | knob | — | Controls 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
|
| Hit | button | — | Manually triggers the envelope, equivalent to a gate/trigger at the Trig input.867 |
| Morph | knob | — | Controls the waveform of all oscillators by continuously blending through sine, triangle, saw, and square. Knob offsets the CV input.867 |
| Pitch | knob | — | Encoder for adjusting pitch — press and turn for coarse semitone steps, or turn alone for fine tuning. Calibrated for 1V/octave tracking.867 |
| Skin/Liquid/Metal | switch | — | Three-position switch that selects the synthesis algorithm: Skin, Liquid, or Metal.867 |
| Spread | knob | — | Controls the frequency spacing between oscillators, sweeping the overtone series from purely harmonic to very inharmonic. Knob offsets the CV input.867 |
