Using the ES M Filter and Filter Envelope

The ES M includes a lowpass filter that lets you contour the output from the oscillator. The filter features a dedicated envelope.

Figure. Filter Envelope parameters.
  • Cutoff knob: Controls the cutoff frequency of the ES M filter. Its slope is 24 dB/octave.
  • Resonance knob: Boosts or cuts portions of the signal that surround the frequency defined by the Cutoff parameter.

    Note: Increasing the Resonance value results in a rejection of bass (low frequency energy) when using lowpass filters. The ES M compensates for this side-effect internally, resulting in a more bassy sound.

  • Int knob: Defines the amount (the intensity or depth) of cutoff frequency modulation applied by the envelope generator.
  • Decay knob: Defines the decay time of the filter envelope.
  • Velo knob: Sets the velocity sensitivity of the cutoff frequency modulation applied by the envelope generator.

    Note: The Decay and Velo parameters have no effect if Int is set to 0.
