|
Dampens the parts of the signal that are above than the cutoff point (typically the crunchy fizzy harmonic overtones) and keeps the lower parts (typicaly the bass/mid of the sound). behaviour, The resonant part of the resonant low pass filter emphasises/resonates the frequencies around the cutoff point. The amount of emphasis is controlled by the res param with a lower res resulting in greater resonance. High amounts of resonance (rq ~0) can create a whistling sound around the cutoff frequency. Choose a higher cutoff to keep more of the high frequences/treble of the sound and a lower cutoff to make the sound more dull and only keep the bass.

The amplitude of the sound. Typically a value between 0 and 1. Higher amplitudes may be used, but won't make the sound louder, it will just reduce the quality of all the sounds currently being played (due to compression.) Default: 1 must be zero or greater May be changed whilst playing Has slide parameters to shape changes |
|
The amount (percentage) of FX present in the resulting sound represented as a value between 0 and 1. For example, a mix of 0 means that only the original sound is heard, a mix of 1 means that only the FX is heard (typically the default) and a mix of 0.5 means that half the original and half of the FX is heard. Default: 1 must be a value between 0 and 1 inclusively May be changed whilst playing Has slide parameters to shape changes |
|
Amplification applied to the input signal immediately before it is passed to the FX. Default: 1 must be zero or greater May be changed whilst playing Has slide parameters to shape changes Scaled with current BPM value |
|
MIDI note representing the highest frequencies allowed to be present in the sound. A low value like 30 makes the sound round and dull, a high value like 100 makes the sound buzzy and crispy. Default: 100 must be zero or greater,must be a value less than 131 May be changed whilst playing Has slide parameters to shape changes |
|
Filter resonance. Large amounts of resonance (a res: near 0) can create a whistling sound around the cutoff frequency. Smaller values produce more resonance. Default: 0.5 must be greater than zero May be changed whilst playing Has slide parameters to shape changes |
|
Amount of time (in seconds) for the parameter value to change. A long parameter_slide value means that the parameter takes a long time to slide from the previous value to the new value. A parameter_slide of 0 means that the parameter instantly changes to the new value. Default: 0 |
|
Shape of curve. 0: step, 1: linear, 3: sine, 4: welch, 5: custom (use curvature param), 6: squared, 7: cubed Default: 5 |
|
Shape of the slide curve (only honoured if slide shape is 5). 0 means linear and positive and negative numbers curve the segment up and down respectively. Default: 0 |
