Skorpion is a stereo analog wavefolder / waveform animator built around a vector core: - Your IN signal is compared against 8 thresholds - Each threshold crossing can reverse the core’s direction - SLOPE sets how fast the core moves - TARGET sets what voltage the core moves toward - SHAPE adds feedback-based contouring - OUTPUT crossfades from dry → wet → stereo widened wet
It can behave like: - a classic-ish wavefolder - a highly asymmetrical folding/distortion source - a CV/audio-rate animation engine - a modulation source generator via its many aux outputs
If it gets too weird/silent while modulating: - turn on DRY IF NO THLDs
Amplifies the input against the threshold stack; more fold activity.
Sets the vector core slew rate. Higher = more harmonic content, brighter/faster motion.
Tracks SLOPE so timbre stays more consistent across pitch.
Offsets the input against thresholds for asymmetry. - Noon = ~0V shift - Slow modulation here can create frequency-shift-like effects
Sets where the vector core tries to go: - 5V: static destination, squarer sounds - CLIP: uses input waveform (or external CLIP jack) as destination overlay - SLIDERs: uses 8 target sliders as a sequenced destination voltage
Modulates SLOPE using a selected feedback/control source. - Noon = no feedback - SYM switch on: shaping is symmetrical for + / – portions of the waveform
Crossfader: - lower half: DRY ↔ WET - upper half: WET ↔ WIDE - WIDE brings in stereo delay/mid-side widening
Forces equal threshold spacing; sounds more like a classic wavefolder. - ON: equalized always on; jack ignored - XOR: equalized on unless jack is high - JACK: equalized off unless jack is high
LED on = thresholds equalized.
If no thresholds are active, forces dry signal through the core. Helpful when heavy modulation causes folding to disappear.
Resets vector core at IN zero crossings: - SOFT: ramps toward 0V at current slope - X: off - HARD: fast reset to 0V
How slider targets are selected: - SEQ: by number of active thresholds - TIED: by most recently crossed threshold
If a target slider is at 0, that segment can stop moving, producing square/held sections.
The 8 sliders serve 3 roles:
Sets the 8 threshold voltages where folds occur.
Sets the 8 target voltages for the target sequencer.
Configures internal modulation.
Skorpion has an internal macro envelope controlling internal LFO/envelope modulation.
For sliders 5–8: - quick top→bottom gesture = LFO mode - quick bottom→top gesture = ENV mode
Behavior: - LFO: 0.0016Hz–6Hz, unipolar, amplitude controlled by Macro Env - ENV: 50ms–600s, gated by Macro Env gate, amplitude not scaled by Macro Env - Routed internally to the corresponding CV normal input
Notes: - LFOs reset on each Macro gate-on - Envelopes attack without resetting on retrigger - LFO disabled at slider bottom; envelopes cannot be disabled
Good aux outputs to patch back in: - DIFF → SHAPE CV for spiky timbres - COUNT → TARGET / SHIFT / SHAPE - ±G(DIR) → SHIFT - TRGTs out → anything - ABS(IN) → modulation destination - DELAY → SHAPE with output in wide region
Manual states IN nominal range is ±5V. Other CV/gate inputs are supported; explicit ranges are only given where stated in the manual. When not explicitly specified, patch typical Eurorack CV/audio.
Input impedances: IN 100kΩ, 1V/OCT 3MΩ, TRGT MOD 20kΩ, all other CV/gate inputs 220kΩ.
