Erica Synths / DAS KLEINE FUSION

Erica Synths' Das Kleine Fusion is the little brother of the Fusion System II, a tube-based Eurorack modular synthesizer that creates unprecedented sonic pressure. Because Das Kleine Fusion is intended for use with external FX, the Fusion Delay module has been omitted, making the system more compact and affordable.

Features

Two Fusion VCO2 Complete analog sound sources with three waveforms available simultaneously, transistor-based sub-oscillators and detuning capabilities.
Two BBD delay lines that create a frequency shifter that is mixed back to the main oscillator to emulate two detuned VCOs.
Tube Crunch adds a unique tube overdrive to the top of the mix.
Fusion VCF3 A uniquely designed resonant 24dB/oct low-pass filter that combines a vacuum tube and a Bactrol to provide a unique and soft filtering experience. For added versatility, a CV recorder is built into the module to record potentiometer movement, allowing design of sophisticated modulation patterns.
Fusion Modulator - a complex all-analog CV source consisting of multiple blocks - Looping Envelope Generator, VCA inspired by the two EMS Synthi functions with simultaneous unipolar (0V to 10V) and bipolar (-5V to +5V), Noise Generator, Sample & Hold.
Fusion VCA/Waveshaper/Ringmodulator Modulation source based on two miniature pentodes acting as VCA, waveshaper and ring modulator.
Simultaneously applying two CVs to different stages of the VCA, audio rate modulation, and using the ringmodulator as a waveshaper makes for an amazingly versatile sound shaping module.
