# WMD — Skorpion - [Manual PDF](../../manuals/SKORPION_Manual.pdf) --- [Manual PDF](#) # WMD Skorpion — Using It to Create Melodic Components Skorpion is not just a wavefolder. It’s really a **waveform-generation and transformation system** with built-in comparator logic, target sequencing, modulation, and stereo processing. That means it can contribute to melody in several different ways: - as a **timbre shaper** for pitched oscillators - as a **pitched voice** enhancer with good tracking via **1V/OCT** - as a **sequenced control-voltage source** - as a **rhythmic/melodic modulation generator** - as a **stereo melodic texture builder** Since only one module/manual is attached here, I’ll focus on how the **internal sections of Skorpion work together** to produce melodic material. --- ## 1. Big picture: why Skorpion is useful for melody At its core: - **IN** receives a waveform - the signal is compared against up to **8 thresholds** - each threshold crossing changes the behavior of the **vector core** - the vector core moves toward a **target voltage** - the movement speed is set by **SLOPE** - **SHAPE** bends that movement with feedback/modulation sources - **TRGTs** can act like an **8-step destination sequencer** - **1V/OCT** lets slope track pitch relationships more consistently So instead of just “distorting” a note, Skorpion can turn a simple oscillator into a **structured melodic voice** whose partials, contour, and even segment-by-segment behavior respond to pitch and threshold crossings. --- ## 2. Most direct melodic use: process a VCO into a playable voice ### Basic patch - Patch a **VCO sine or triangle** into **IN** - Send your keyboard/sequencer pitch CV to: - the VCO’s **1V/OCT** - Skorpion’s **1V/OCT** - Take **OUT L** or **OUT R** to your mixer/VCA/filter ### Why this works The manual notes that **1V/OCT controls slope and is necessary for equal timbre across different notes**. That is a big clue: if you want a melodic line where the character stays relatively consistent as pitch changes, you should track both the oscillator and Skorpion together. ### Good starter settings - **FOLD**: low to medium - **SLOPE**: medium - **SHIFT**: noon - **TARGET**: between **CLIP** and **5V** - **SHAPE**: noon initially - **EQUALIZE THLDs**: ON for more classic, harmonically stable folding - **SYNC**: SOFT or HARD if you want tighter periodic behavior ### Result You get a more playable, controlled melodic voice than wild random folding. This is the best place to start if your goal is **leads, basses, or arpeggios**. --- ## 3. Use the thresholds and targets together as a melodic articulation system A key melodic feature of Skorpion is that the **sliders can define thresholds or targets**, and the **targets form an 8-step voltage-controlled sequencer**. ### What this means musically Each time the input crosses thresholds, the vector core can be redirected toward a different voltage. That can make one incoming oscillator produce **different segment shapes within each cycle**, which changes perceived pitch color, attack profile, and overtone emphasis. ### Patch concept: “sequenced timbre melody” - Send a steady pitched waveform to **IN** - Set **TARGET** toward **SLIDERs** - Hold spring toggle left and program **TRGTs** - Set **TARGET ORDER**: - **SEQ** for ordered progression by active-threshold count - **TIED** for behavior tied to the most recently crossed threshold ### Musical result Instead of a static folded tone, each waveform cycle can move through a **mini-sequence of destination voltages**. This often sounds like: - animated vowel-ish leads - stepped harmonic changes within a note - pseudo-wave-table melodic movement This is especially powerful for **melodies with long sustained notes**, because the note itself contains internal motion. --- ## 4. Use Skorpion as a melodic CV sequencer The manual explicitly states that the **TRGTs output jack** gives direct connection to the target sequencer and can be used as: - an **8-step wavetable oscillator** - a modulation source for other parameters That means Skorpion can generate control voltages related to threshold activity. ### Patch concept: derive melody from audio - Patch an oscillator or complex modulation source into **IN** - Program the **TRGT sliders** with 8 voltages - Patch **TRGTs OUT** to: - another oscillator’s **1V/OCT** for stepped melody - a quantizer, then to **1V/OCT** - filter cutoff for melodic contour-like motion ### Best supporting settings - Use **TARGET ORDER = SEQ** for more predictable progression - Use **EQUALIZE THLDs ON** if you want more regular threshold spacing - Use a simple periodic waveform at **IN** for stable repeated patterns - Use **SYNC** for more repeatability ### Musical result Skorpion becomes a kind of **audio-driven step sequencer**. The pitch sequence is not clocked traditionally; it is generated by the way the input crosses thresholds. This is excellent for: - self-playing generative melodies - deriving related melodic lines from one root oscillator - turning audio rate motion into quantizable step patterns --- ## 5. Use the auxiliary outputs as melodic sources Several outputs can be used to build melody or melody-adjacent modulation. ## TRGTs OUT Best direct melodic source. Use it for: - pitch CV into a quantizer - FM index changes per threshold segment - transposition patterns ## COUNT output A staircase from **0–4V**, each active threshold adding **0.5V**. Use it for: - quantized melodic steps - transposition levels - driving a sequential switch or quantizer Because COUNT is evenly stepped, it is often easier than TRGTs when you want **structured interval motion**. ## DAC output A weighted version of count, like a binary-weighted aggregate of threshold states. Use it for: - more nuanced pseudo-melodic CV - irregular melodic intervals - probabilistic-feeling pitch movement after quantization ## DIFF output Difference between target voltage and current vector core state. It slopes toward 0V and is harmonically rich. Use it for: - audio-rate FM of another oscillator - highly animated pitch-adjacent modulation - per-note transient pitch effects Not ideal as a clean pitch source, but excellent for **expressive melodic instability**. ## G(IN>0) and ±G(DIR) These are gate/bipolar gate outputs. Use them for: - triggering envelopes in sync with waveform polarity - clocking sequencers/dividers - switching melodic destinations - transposition logic A melodic patch becomes far more interesting if pitch changes are coordinated with these gate-derived events. --- ## 6. Best melodic patch types ## A. Stable lead voice **Goal:** playable lead with harmonic animation - VCO saw/triangle → **IN** - pitch CV → VCO **1V/OCT** and Skorpion **1V/OCT** - **OUT L/R** → VCA → mixer - **EQUALIZE THLDs ON** - **TARGET = 5V** or slightly toward **SLIDERs** - **SYNC = SOFT** - moderate **FOLD** - low/moderate **SHAPE** **Why:** Equal thresholds and 1V/OCT tracking keep timbre more consistent note-to-note. --- ## B. Melodic bass with pulse-like articulation **Goal:** bassline with internal square-ish segments - Triangle VCO → **IN** - **HALT IF TARG=0 ON** - Set some **TRGT sliders** to bottom (0) - **TARGET** toward **SLIDERs** - **TARGET ORDER = TIED** - **SHIFT** near noon - **OUT** → lowpass filter/VCA **Why:** When a target is 0, that segment can halt, creating square-ish plateaus. On bass notes this gives strong, punchy, melodic articulation. --- ## C. Audio-driven sequencer for melody **Goal:** turn one oscillator into pitch sequence data - Clocked or tuned VCO/LFO → **IN** - Program **TRGT sliders** as a pitch pattern - **TRGTs OUT** → quantizer → another VCO **1V/OCT** - Optional: **G(IN>0)** or **±G(DIR)** to trigger envelopes **Why:** Threshold crossings select targets, yielding a repeating but timbrally linked melodic pattern. --- ## D. Counter-melody from COUNT **Goal:** related second voice - Main melody oscillator → **IN** - **COUNT OUT** → quantizer → second oscillator **1V/OCT** - Main processed signal from **OUT** - Second oscillator mixed alongside **Why:** The second oscillator follows threshold-activity complexity of the first voice, producing a companion melodic line. --- ## E. Stereo melodic texture / pad **Goal:** wide evolving harmonic line - Slow melodic oscillator or sequence → **IN** - **OUTPUT** past noon toward **WIDE** - **OUTPUT SWITCH = FILTERS** - Add slow modulation to **SHIFT** or **SHAPE** - Use **DELAY OUT** as extra modulation or audio layer **Why:** Skorpion’s stereoizing network and delay turn a simple melody into a spatial melodic texture, especially useful for ambient or cinematic patches. --- ## 7. How the controls affect melody specifically ## FOLD This changes how strongly the input is pushed into the comparator/threshold system. For melody: - lower values preserve pitch clarity - higher values produce brighter, more aggressive harmonic intervals - extreme modulation can obscure pitch, but also create vocal leads Use moderate amounts if note identity matters. ## SLOPE Very important for melodic behavior. For melody: - lower slope = smoother, darker, more filtered behavior - higher slope = brighter, more harmonically dense - with **1V/OCT**, slope can track pitch for more consistent timbre This is one of the most important controls for keeping the module “musical” across a melodic range. ## SHIFT Adds asymmetry by offsetting the input against thresholds. For melody: - subtle shift = richer odd/even harmonic variation - slow modulation = frequency-shift-like movement - too much can destabilize symmetry and pitch feel Excellent for expressive melodic phrasing. ## TARGET Changes where the vector core is trying to go. For melody: - **5V** gives more square, defined waveforms - **CLIP** overlays behavior with the input waveform - **SLIDERs** opens up sequenced internal motion For melodic purposes, this is one of the strongest “personality” controls. ## SHAPE Feedback-based slope modulation. For melody: - **OUT** source can create log/exp contour shaping - **IN** source tracks the incoming waveform - **DIFF** gives harsh, transient-rich sounds - **TRGTs** makes segment-by-segment shaping possible If the patch is too wild, return SHAPE toward noon. --- ## 8. Use the macro system to animate melodies over time Skorpion’s **Macro Setup** can internally modulate: - thresholds - fold - slope - shift - shape The macro envelope is an attack/sustain/release envelope controlling LFO amplitude system-wide. ### Why it matters for melody You can make each note or phrase evolve in a repeatable way without external modulation sources. ### Useful ideas #### Per-note timbre bloom - Enable macro envelope - Assign an **ENV** or **LFO** to **FOLD** - Trigger macro via **MACRO ENV jack** Result: notes open up harmonically over time. #### Phrase evolution - Slow **THLD LFOs** - moderate **THLD LFO amount** - macro envelope with long attack/release Result: threshold positions drift gradually, causing recurring melodies to subtly change contour over bars. #### Dynamic articulation - Assign **ENV** to **SLOPE** - Assign **LFO** to **SHIFT** Result: each note starts one way and evolves into another, like acoustic phrasing. For melodic patches, the macro system is especially useful because it creates **repeatable motion** rather than random chaos. --- ## 9. Sync, dry-if-no-thresholds, and equalized thresholds: important “musicality” switches ## EQUALIZE THLDs For melody, this is often the secret weapon. - Makes thresholds evenly spaced - Sounds more like a classic wavefolder - gives more regular, predictable overtone behavior Use this when you want: - tonal consistency - easier tuning of timbral character - less surprise across melodic intervals ## DRY IF NO THLDs If no thresholds are active, output becomes the dry signal and the vector core follows input. Use this when: - heavily modulating FOLD - you want to guarantee audible signal on every note - you want safer live-performance melodic behavior This helps avoid patches where some notes disappear. ## SYNC Resets the vector core at zero crossings. - **SOFT**: smoother, more natural - **HARD**: more precise, more aggressive - **X**: freer, less controlled For melodic clarity, **SOFT** or **HARD** usually helps, especially on bass or leads. --- ## 10. Melodic self-patching ideas Skorpion is particularly strong when self-patched. ## TRGTs OUT → SHAPE CV This creates segment-dependent contour changes. Good for animated leads. ## COUNT OUT → SHIFT CV As more thresholds are active, asymmetry changes. Good for dynamic melodic phrasing. ## DAC OUT → TARGET CV Makes destination voltage respond to threshold-state complexity. Good for pseudo-chaotic melodic motion. ## ±G(DIR) → external switch or logic Use direction to alternate between two melodic destinations. ## ABS(IN) OUT → FOLD CV or another oscillator FM Creates full-wave-related modulation tied to input pitch. These kinds of self-patches can produce **internally coherent melodies**, because the modulation derives from the same waveform that generates the sound. --- ## 11. Best external module pairings for melody Skorpion works especially well with: - **stable analog or digital VCOs** for a predictable input waveform - **quantizers** because TRGTs, COUNT, and DAC outputs become very musical once snapped to scale - **sequencers** to drive the source oscillator while Skorpion adds internal sub-structure - **VCAs and envelopes** to shape the rich outputs into articulated notes - **filters** to tame brighter settings for bass and lead work - **logic/clock utilities** to use G(IN>0) and ±G(DIR) for melodic event generation - **second oscillator** for counterpoint driven by TRGTs/COUNT/DAC --- ## 12. Practical melodic recipes ## Recipe 1: Singing lead - Sine VCO into IN - pitch CV multed to VCO + Skorpion 1V/OCT - Equalize THLDs ON - Sync SOFT - Target near CLIP - Small SHAPE from OUT - Slight SHIFT modulation This gives a vocal, expressive lead with strong pitch focus. ## Recipe 2: Metallic arpeggio - Triangle or saw into IN - Target to SLIDERs - Program alternating high/low TRGTs - Target order = SEQ - COUNT out to quantizer for second oscillator - Output wide with FILTERS This yields one bright animated arp plus a derived second melodic line. ## Recipe 3: Bass with internal steps - Triangle in - Sync HARD - Slope medium-high - Halt if targ=0 ON - Some TRGT sliders at 0, others high - Filter after output This creates stepped, assertive bass tones. ## Recipe 4: Generative melody machine - Cycling LFO or oscillator in - THLD LFO amount up - Slow THLD LFO rate - TRGTs out to quantizer - G(IN>0) to envelope trigger - Processed output mixed quietly under the quantized voice This makes Skorpion both the sound source modifier and the melodic CV engine. --- ## 13. Overall assessment For melodic music, Skorpion is best understood as a hybrid of: - wavefolder - comparator-based control system - vector oscillator core - 8-step target sequencer - modulation generator - stereo texturizer Its strongest melodic roles are: 1. **tracking timbre processor for an oscillator voice** 2. **internal sequenced waveform shaper** 3. **source of pitch-capable stepped CV via TRGTs/COUNT/DAC** 4. **generator of related counter-melodies and phrase modulation** If you want traditional clean subtractive melody, Skorpion is not the shortest path. If you want **melodies with internal movement, harmonic articulation, and derived companion CV**, it is extremely powerful. --- ## Best first melodic patch to try If you only try one: - Oscillator → **IN** - pitch CV → oscillator + **Skorpion 1V/OCT** - **EQUALIZE THLDs ON** - **SYNC SOFT** - **TARGET** midway between **CLIP** and **SLIDERs** - program a simple rising/falling **TRGT** pattern - take **OUT L** as your main voice - send **COUNT OUT** to a quantizer and then to a second oscillator That gives you: - a main melodic voice - sequenced internal timbre motion - a derived counter-melody That’s where Skorpion really shines musically. --- [Generated With Eurorack Processor](https://github.com/nstarke/eurorack-processor)
