Dampens the parts of the signal that are lower than the cutoff point (typicaly the bass of the sound) and keeps the higher parts (typically the crunchy fizzy harmonic overtones). Choose a lower cutoff to keep more of the bass/mid and a higher cutoff to make the sound more light and crispy.
Introduced in v2.0
|
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 |
|
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 |
