Matthias Puech and 4ms' Ensemble Oscillator Enables Limitless Voice Capabilities, Harmonics, and Textures 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. 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, repeating over octaves 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 SPECIFICATIONS 16HP Eurorack format module 0.98" (25mm) maximum depth (including power cable) 10-pin to 16-pin Eurorack power header Power Consumption +12V: 114mA maximum -12V: 45mA maximum +5V: 0mA (not used) Audio Outputs Frequency Range: 0Hz (DC) - 20kHz Typical Amplitude: 10Vpp Maximum Amplitude: 18.5Vpp 1V/oct inputs (Root and Pitch) Voltage range: -2V to +6V (8 octave range) Factory calibrated to 1.00V/oct Per-jack user-calibration allows from 0.7V/oct to 1.3V/oct CV inputs (other than 1V/oct) Voltage range: -5V to +5V Gate inputs Trigger threshold: 2.5V User memory (non-volatile) Scale slots: 30 Shift feature settings 1V/oct calibration settings Manufacturer: 4msModel: ENOSCBSKU: I666929-N-0-WHXBWe are Chuck Levin's Washington Music CenterSince 1958, Chuck Levin’s Washington Music Center has been the trusted destination for musicians and audio professionals across Maryland, Virginia, and Washington, D.C.
