|
Like the Band Pass Filter but normalized, with a resonance (slight volume boost) around the target frequency. This can produce an interesting whistling effect, especially when used with smaller values for the res argument. The normalizer is useful here as some volume is lost when filtering the original signal.

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 |
|
Centre frequency for the filter in MIDI. Default: 100 must be a value greater than or equal to 0 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,must be a value less than or equal to 1 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 |
