# Noise Engineering — Basimilus Iteritas Alia - [Manual PDF](../../manuals/Basimilus Iteritas Alia Manual - Noise Engineering Documentation.pdf) --- [Basimilus Iteritas Alia Manual PDF](https://manuals.noiseengineering.us/bia/) # Using Basimilus Iteritas Alia for melodic music Basimilus Iteritas Alia (BIA) is presented as a **digital drum voice**, but the manual makes clear it can also function as a strong **melodic oscillator/synth voice**. In particular, it works well for **basslines, leads, stabs, supersaws, harsh FM-style tones, and sequenced pitched percussion**. ## Why it works melodically From the manual: - **Pitch input is calibrated for 1V/oct tracking** - Pitch CV range is **-2 V to +5 V** - There is a **Pitch encoder** for fine or coarse semitone tuning - It has multiple synthesis modes: - **Skin**: additive, more tonal - **Liquid**: additive with pitch envelope, great for punchy melodic tones - **Metal**: phase-modulated, noisier and more inharmonic, but still useful for aggressive bass/lead sounds - It includes an **Env Out**, which mirrors the internal envelope and can modulate other modules This means BIA can be treated as a full synth voice when paired with: - a **pitch sequencer** - a **trigger/gate source** - optional **modulation** - optional **filter, VCA, effects, or wave shaping** --- ## Best melodic roles for BIA ## 1. Bassline voice BIA is especially strong for bass. ### Recommended setup - Send a **pitch sequence** to **Pitch** - Send a **gate/trigger pattern** to **Trig** - Take **Out** to your mixer, filter, or effects - Use **Bass** range switch to place it in bass register - Start with **Skin** or **Liquid** ### Good controls for bass shaping - **Morph**: moves through sine, triangle, saw, square. Lower settings can give more solid low-end; more aggressive settings add bite. - **Harmonic**: keep lower for simpler bass fundamentals, or increase for more overtone weight. - **Spread**: low or harmonic settings help preserve tonal clarity. - **Fold**: adds aggression and harmonics; useful for acid-like or distorted bass. - **Decay**: controls note length. - **Attack**: center or slightly right for cleaner onset; left of center adds noise, which is less typical for clean bass but useful for edge. ### Especially useful mode - **Liquid** adds pitch envelope internally, which can make basslines feel more punchy and animated even without external modulation. --- ## 2. Lead voice BIA can make sharp, cutting leads with a lot of harmonic motion. ### Recommended setup - Pitch sequencer to **Pitch** - Trigger/gate sequence to **Trig** - Use **Alto** or **Treble** - Patch **Out** to delay/reverb for space ### Good approaches - **Skin** for brighter, more stable melodic leads - **Metal** for aggressive industrial or experimental lead timbres - Moderate **Spread** gives richer overtone spacing - Increase **Fold** for growl and articulation - Modulate **Morph** or **Fold** slowly with CV for evolving phrases ### Musical result This works particularly well for: - techno leads - EBM/industrial hooks - arpeggios - distorted mono leads --- ## 3. Chord-like or supersaw-style melodic textures The manual includes a **Supersaw** patch concept, which is very important melodically. Because BIA uses multiple oscillators, **Spread** can create detuned or interval-rich textures that feel wider and more chordal than a simple single oscillator. ### Patch concept - Pitch CV sequence to **Pitch** - Trigger pattern to **Trig** - Use **Skin** - Increase **Spread** - Adjust **Morph** toward brighter waveforms - Use moderate **Harmonic** - Use longer **Decay** ### Pair with - stereo delay - chorus - reverb - filter modulation This can yield: - unison-style leads - pseudo-chord stabs - trancey supersaw-ish lines - big melodic riffs --- ## 4. Plucked or struck tonal sequences Because BIA has an internal envelope and percussive architecture, it naturally excels at **plucks**, **mallets**, and **pitched strikes**. ### Best mode - **Skin** for clean struck tones - **Liquid** for kick-like plucked bass - **Metal** for bells, clangs, and tuned metallic hits ### How to patch - Clocked trigger source into **Trig** - Quantized pitch CV into **Pitch** - Short-to-medium **Decay** - Tune with encoder - Use **Attack** near center for a punchy transient This is a strong method for: - marimba-like sequences - tuned tom patterns - melodic percussion lines - electro-style tonal hits --- ## 5. FM-like melodic bass and metallic melody The manual explicitly includes a **“Not quite FM bass”** patch. That indicates BIA is very capable of FM-adjacent melodic sounds. ### Use **Metal** mode for: - metallic bass - alien leads - tuned industrial percussion - digital bell-like phrases ### Main sound design controls - **Spread** changes interval relationships / inharmonicity - **Harmonic** affects overtone envelope behavior - **Morph** changes waveform foundation before modulation complexity - **Fold** adds further density and harshness This is ideal for: - IDM - industrial - broken beat - dark techno - soundtrack design --- ## How to combine BIA with other modules for melodic systems Even though only BIA is shown here, the manual strongly suggests how it behaves in a larger patch. Here are the most useful pairings. ## A. With a sequencer or quantizer This is the most important pairing. ### What the second module should do - Output **1V/oct pitch CV** - Output corresponding **triggers/gates** ### Result BIA becomes a playable mono synth voice. ### Best uses - basslines - riffs - arps - tuned percussion Because BIA is trigger-based, the sequencer does not need to sustain notes traditionally; it just needs to trigger the internal envelope rhythmically. --- ## B. With an envelope or function generator BIA already has an internal envelope, but external modulation makes it much more melodic and expressive. ### Patch external modulation to: - **Morph** - **Fold** - **Spread** - **Decay** - **Attack** - **Harm** ### Musical benefit You can create: - accent variation - timbral phrasing - note-to-note articulation changes - evolving melodic loops A slow envelope or random stepped CV to **Morph** or **Fold** is especially effective. --- ## C. With a filter BIA does not need a filter to sound good, but a filter can make it sit more naturally in melodic roles. ### Why use one - tame harsh highs from **Fold** - shape bass emphasis - animate leads with filter sweeps - make metallic tones more tonal ### Strong use cases - lowpass after **Metal** mode for aggressive but focused bass - bandpass after **Skin** for vocal or nasal leads - resonant lowpass after **Liquid** for punchy acid-adjacent lines --- ## D. With a VCA Since BIA already contains its own envelope, a VCA is optional for basic use, but still useful. ### Why - dynamic control from another envelope - sidechain-style pumping - amplitude automation independent of BIA’s internal contour - ducking and mix placement ### Nice trick Use **Env Out** to modulate another VCA or filter elsewhere in the patch while BIA plays melody. --- ## E. With effects BIA becomes much more “synth-like” melodically when sent through effects. ### Best effect pairings - **Delay**: for arps and lead echoes - **Reverb**: for spacious melodic percussion and lead atmospheres - **Chorus/ensemble**: for supersaw and widening - **Distortion/saturation**: for industrial bass and lead - **Phaser/flanger**: for animated metallic lines --- ## F. Using Env Out as a melodic patching tool One of the biggest advantages of the Alia version over the original is **Env Out**. The manual says it outputs an envelope mirroring BIA’s internal envelope, from **0 V to +5 V**. ### This lets BIA control other modules while playing melody Examples: - Open a filter on another oscillator in sync with BIA notes - Modulate another VCA for layered synth attacks - Trigger dynamic effect depth - Animate wavefolder amount on another voice - Create layered bass + click systems where BIA shapes another sound ### Very musical application Use BIA as the main bassline, and route **Env Out** to: - a filter cutoff on a second oscillator - a VCA controlling sub bass - effect send level for note-by-note dub-style echoes This makes BIA not just a voice, but also a **performance modulation source**. --- ## Mode-specific melodic recommendations ## Skin Best for: - bass - plucks - supersaw-like textures - synth stabs - clearer melodic parts Why: - additive structure is more stable and tonal - easier to tune musically - better for conventional note sequences ## Liquid Best for: - punchy basslines - acid-like stabs - percussive melodic hooks - tom-like tuned sequences Why: - built-in pitch envelope adds attack character - great for lines that need movement and impact ## Metal Best for: - industrial melodies - aggressive FM-ish bass - bells and clangorous tuned sounds - experimental lead work Why: - more inharmonic and complex - phase modulation creates richer, noisier spectra --- ## Parameter strategies for melodic patching ## For clean tonal bass - Mode: **Skin** - Range: **Bass** - Morph: lower to mid - Harmonic: low to mid - Spread: low - Fold: low to moderate - Attack: center - Decay: medium ## For punchy techno bass - Mode: **Liquid** - Range: **Bass** - Morph: mid - Harmonic: low-mid - Spread: low - Fold: moderate - Attack: center/right of center - Decay: short-medium ## For bright lead - Mode: **Skin** - Range: **Alto/Treble** - Morph: saw/square area - Harmonic: medium-high - Spread: medium - Fold: moderate-high - Decay: medium - Add delay/reverb ## For metallic melody - Mode: **Metal** - Range: **Alto/Treble** - Morph: experiment broadly - Harmonic: medium - Spread: medium-high - Fold: low to moderate at first - Decay: medium-long ## For tuned percussion line - Mode: **Skin** or **Metal** - Range: depends on register - Decay: short - Attack: center - Harmonic: moderate - Spread: adjust by ear for tonal center --- ## Important voltage and patching notes From the manual: - **Trig threshold**: around **+1.8 V** - Modulation CV inputs: **0 V to +5 V** - Pitch CV range: **-2 V to +5 V** - **Env Out**: **0 V to +5 V** - Audio output can reach about **14 Vpp** This means: - standard Eurorack sequencers and triggers should work fine - attenuating modulation sources may help when patching into parameter CV inputs - audio may be hot, so watch gain staging into external mixers, interfaces, or effects --- ## Best musical workflows ## 1. Single-voice melodic synth - Sequencer pitch out → **Pitch** - Gate/trigger out → **Trig** - BIA **Out** → mixer/effects Use for: - mono bass - lead - stab line ## 2. Layered bass patch - Same as above - **Env Out** → filter cutoff or VCA on second oscillator/sub source Use for: - bass with synchronized transient shaping - layered punch and sub ## 3. Melodic percussion engine - Quantized random or sequenced CV → **Pitch** - Rhythmic triggers → **Trig** - Short decay - Optional modulation to **Morph** or **Spread** Use for: - tuned toms - bell patterns - electro hits ## 4. Evolving lead - Sequencer → **Pitch** - Trigger pattern → **Trig** - Slow LFO or envelope → **Morph** - Random stepped CV → **Fold** or **Spread** - Delay/reverb after output Use for: - animated melodies - live performance variation - generative hooks --- ## Overall takeaway Basimilus Iteritas Alia is not limited to drums at all. Based on the manual, it is highly effective as a: - **bass voice** - **lead voice** - **pitched percussion voice** - **supersaw/unison-style synth** - **metallic/FM-like melodic oscillator** - **modulation source via Env Out** Its strongest melodic advantage is that it combines: - pitch tracking, - rich multi-oscillator tone generation, - internal transient/envelope behavior, - aggressive timbral shaping, - and patchable envelope output. In a Eurorack system, that makes it excellent for **sequenced melodic lines with strong articulation**, especially in techno, industrial, electro, IDM, experimental, and hybrid drum/synth compositions.
