ES M filter and filter envelope in Logic Pro for iPad
ES M includes a lowpass filter that lets you contour the output from the oscillator. The filter has a dedicated envelope.
Filter and filter envelope parameters
Cutoff knob and field: Set the cutoff frequency of the filter. Its slope is 24 dB/octave.- Resonance knob and field: Boost or cut 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.
Env Depth knob and field: Define the amount (depth) of cutoff frequency modulation applied by the envelope generator.
Decay knob and field: Set the decay time of the filter envelope.
Env Velo knob and field: Set the velocity sensitivity of the cutoff frequency modulation applied by the envelope generator.
Note: The Env Decay and Env Velo parameters have no effect if Filter Depth is set to 0.
