Klowra | VEIN | 17-Interval Polyphonic Pitch-Shifter w/ Studio-Grade 32-Bit DSP & Microtonal Precision
Klowra Vein – 17‑Interval Polyphonic Pitch‑Shifter Pedal
Precision Pitch Shifting, Harmonies, Octaves & Glide Modes with Ramp, Stereo Output & USB‑C Firmware
Overview
The Klowra Vein is a high-performance polyphonic pitch-shifting pedal designed for guitarists, synth players, and creative sound designers. Powered by the WildSeed Engine (24-bit AD/DA, 32-bit float DSP), Vein delivers 17 pitch intervals—from semitone shifts to dual-octave slides—in a low-latency, studio-grade platform. With LFO-based microtonal modulation, Glide-in/Momentary mode, Ramp transitions, true stereo output, analog dry-through, and external footswitch/expression control, Vein combines precision and expressive flexibility in a rugged pedalboard-ready chassis .





Key Features
-
17 Precision Pitch Intervals
Choose from semitones (±1 to ±2, perfect fourth, perfect fifth, major/minor thirds) up to full octaves and dual-octave shifts, enabling harmonization, drone layers, or melodic leaps .
-
Polyphonic, Low-Latency Engine
Delivers clean shifts and robust performance without detuning or glitchiness—even with complex chord voicings .
-
Glide & Ramp Modes
Hold the footswitch for smooth pitch transitions (Ramp) or instant nerdy pitch slides (Glide Attack/Release) via momentary or latching footswitch .
-
LFO Microtonal Modulation
Intriguing pitch wobble and stereo width effects apply subtly microtonal variations for a rich, evolving sound .
-
Analog Dry Through & Switchable Bypass
Preserves original tone in analog; power-up toggle between True or Buffered Bypass for trails or tone consistency .
-
Stereo and Dry/Wet Output Modes
Offers full stereo with immersive pitch layering or distinct dry/wet separation on output paths .
-
External Expression & Footswitch Control
TS/TRS compatibility for external pedals to modulate pitch, Glide, or Ramp functions live .
-
Stay current with the latest updates—firmware v1.1.0 brings refined tone realism, responsiveness, and functional improvements .
