Nano Modules ONA

Voltage-Controlled Analog Oscillator

8 HP Eurorack module

ONA is a voltage-controlled analog oscillator that works as an audio oscillator or low-frequency modulator.

Features

  • Four classic outputs: sine, triangle, sawtooth, and pulse.
  • Two complex waveform outputs and two square-wave sub-oscillator outputs.
  • External synchronization resets oscillator phase.

Controls & Jacks (19)

  • Fine Adjust— Fine tuning control in VCO and LFO modes, with an approximately ±7-semitone range around center.
  • Octave Adjust— Eight-position coarse tuning control; each position adds one octave to the oscillator frequency.
  • FM Attenuator— Attenuates the external voltage applied to the FM Input.
  • SYNC Input— Resets the oscillator waveform phase from an external ±5 V waveform for synchronization or related sound effects.
  • PW Attenuator— Sets the base pulse width when no PW cable is connected; when a PW signal is connected, attenuates that signal's modulation depth.
  • Sub -1 Octave Output— Square-wave sub-oscillator output one octave below the main tuning.
  • Sub -2 Octave Output— Square-wave sub-oscillator output two octaves below the main tuning.
  • Complex 2 Output— Complex 2 output: a saw wave mixed with a PWM pulse.
  • FM Mode— Selects linear or exponential response for the FM Input.
  • OCT Input— Primary 1 V/oct pitch-control input.
  • Complex 1 Output— Complex 1 output: a triangle wave mixed with a PWM pulse.
  • Mode— Selects VCO mode (20 Hz to above 40 kHz) or LFO mode (periods over one minute through low audio rates).
  • Sawtooth Output— Sawtooth-wave output.
  • PW Input— Controls pulse-width modulation of the Pulse and Complex outputs; expected control range is 0–5 V.
  • Triangle Output— Triangle-wave output.
  • FM Input— Frequency-modulation input; its response is selected as linear or exponential and its depth is set by the FM Attenuator.
  • Pulse Output— Variable-duty-cycle pulse-wave output.
  • Level Indicator— Independently located level indicator for the oscillator.
  • Sine Output— Sine-wave output.
