LittleOne GUI

LittleOne - imperfection is beauty, also with instruments

LittleOne synthesizer is entirely built upon this concept. The adoption of the Advanced Component Simulation (ACS) approach ensures that every component inside LittleOne is simulated preserving its original analogue hardware architecture and physical properties - including its own micro-imperfections and unique, time-varying instabilities.

This means that - playing the same note twice - LittleOne will never produce exactly the same sound, not in a million years or more. Just as nature teaches us.


  • Physical modeling simulation of real analogue hardware, achieved by the adoption of the Advanced Component Simulation (ACS) approach - oscillators, filters, envelopes (,...) are built preserving their original architecture, featuring all the micro-instabilities and imperfections of the analogue technology.

  • A legendary 4-pole resonant low pass ladder filter provides all the original non-linearities, frequency responses (also at extreme modulation scenarios), self-oscillation, soft-clipping and overload control.

  • Two 4-stage (ADSR) envelope generators proving the same capacitors' charging/discharging responses as found on the original analogue circuits.

  • Extended modulation possibilities, including a white noise generator, a sample-and-hold source and a multi-waveform low-frequency-oscillator (LFO) featuring the original frequency range (from 0.2 Hz up to 500 Hz), allowing for advanced frequency modulation designs.

  • True analogue polyphony. In addition to a classic monophonic mode, polyphony (4-voices) is achieved by simulating four fully-independent synthesis systems (devices) separately, as expected in the original hardware specification extension.

  • Including XSQ16A unit (rack), a monophonic 16-step sequencer.

  • Including GAT3D unit (rack), a 16-step trancegate effect.

  • Two insert / master effects slots : X-TREME (tube distortion), FLANG-R (flanger), CHOR-S (chorus), D-LAY (tempo-synced delay), REEVERB (resonator-based reverb)

  • 400+ ready-to-use factory presets collection covering many different styles

  • MIDI automation, with CC# mapping
