Seriously potent polyphonic voice built around 16 sine-based oscillators. Capable of a huge range of tones thanks to FM, phase distortion and wavefolding. Another cracker from a consistently reliable brand. Supplier's notes: 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. 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 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
