4ms - Ensemble Oscillator [ENOSC]
The Ensemble Oscillator is a unified polyphonic voice of sixteen complex oscillators combining additive, FM, phase-distortion and wavefolding synthesis techniques in new unorthodox ways. By quantizing the oscillators to scales or series of harmonics, the Ensemble Oscillator allows you to explore the sonic boundary between musical chords and rich evolving textures. Easily create a wide variety of sounds ranging from aggregates of pure sine waves to pulsar synthesis or pristine harmonic tones and lush wide chords to rich dirty drones and rumbling glitches. Custom scales can quickly be "learned" and saved using a CV keyboard or by manually entering notes with the controls.
The Ensemble Oscillator is designed by Matthias Puech and 4ms Company.
Firmware is open source and available on the 4ms github
Features
- 16 sine-based oscillators bound to intervals of a selected Scale
- 30 factory-programmed, user-writeable scales organized in three groups:
- 12TET: all notes quantized to equal temperament
- Octave: unquantized notes, repeating over octaves
- Free: unquantized notes, repeating over the interval between the lowest and highest note
- A simple method to program ("Learn") your own scales manually or with a CV/Gate keyboard
- Three Twist phase distortion effects
- Three Warp wave distortion effects
- Three algorithms of Cross FM for modulating the oscillators with each other
- Mono or stereo output with selectable panning algorithm
- Freeze button and jack to freeze the frequency of some of the oscillators, with selectable algorithm
- Two 1V/oct inputs: Pitch (non-quantized), and Root (quantized)
- High-accuracy, temperature-stable, eight octave range (-2V to +6V), can be calibrated to any keyboard
- Six bi-polar CV inputs (-5V to +5V)
- Two gate inputs for automated Learning and Freezing
