K112E

Hügelton Instruments is an independent electronic instrument company and design lab founded by Leo Kuroshita in Kobe, Japan. We design Eurorack modules, audio plugins, and experimental music tools inspired by vintage electronics and modern technology.

The K112E digital compound oscillator is a Eurorack module built on our own "Island Synthesis" philosophy. Three independent oscillators and a range of wavetable synthesis techniques combine to produce rich, layered sound.

K112E is a revised edition of the original K102E, redesigned around user feedback. It keeps the K102E's core architecture and sound while significantly expanding voltage control and switching.

Improvements over the K102E

• Added CV: OSC A BANK / OSC B BANK / HARMONICS / COMPOUND ALPHA / LFO DEPTH / LFO FORM / LFO SPEED
• Added switches: COMPOUND MODE (FADE / PHASE / MULT), LFO FOR (OSC 1+2 / OSC 2 / pitch off), LFO to ALPHA, SYNC DIR, OCTAVE
• DETUNE and SYNC carry over from the K102E (DETUNE switches OSC B to track OSC A)

Features

• Rich sound generation from three independent oscillators
• Stable oscillation and diverse wavetable synthesis via onboard DSP
• Main oscillators (A/B) behave like a conventional complex oscillator
• Choose from three synthesis modes (phase modulation, multiplication, crossfade)
• Hard sync and detune
• 8 waveform types inspired by '80s wavetable synthesizers
• Precise wavetable read-position control via harmonic index
• Third oscillator (C) doubles as an auxiliary oscillator
• Selectable frequency range from low to high
• Also usable as an LFO or cross-modulator
• External control interface including standard CV input (octave/volt control), harmonics CV (wavetable read position), and alpha-parameter CV for waveform synthesis
