depth	depth of the chorus effect	0 to 1

compressor

Parameter name	Description	Range
threshold	Decibel value above which compression starts	-100 to 0
knee	The sound level in decibels at which the compression kicks in	0 to 40
ratio	The amound of change in dB needed in the input for a 1 dB change in the output	1 to 20
attack	Amount of time to reduce the gain by 10dB (in seconds)	0 to 1
release	Time required to adapt rate back up by 10 dB (in seconds)	0 to 1

deep_phaser

Parameter name	Description	Range
rate	rate of the phaser (Hz)	0.1 to 10
spread	extent of stereo effect	0 to 1
feedback	amount of feedback in the phaser network	0 to 1
depth	the depth of the phaser effect	0 to 1
resonance	set the resonance, larger number give a stronger effect	0 to 1

distortion

Parameter name	Description	Range
preGain	Gain before distortion is applied	typically 0.5 to 10
postGain	Gain after distortion is applied	typically 0.1 to 1
frequency	Center frequency of the bandpass filter (Hz)	typically around 1500 Hz
bandwidth	Bandwidth of the bandpass filter	0.1 to 100

flanger

Parameter name	Description	Range
rate	Rate of the flanger (Hz)	0.1 to 10
delay	The delay of the flanger (ms)	0.1 to 10
feedback	Amount of feedback, higher values give a stronger effect	0 to 1
depth	The maximum deviation from the delay (ms)	0 to 10

gainpan

Provides simple controls for adjusting level and panning.

Parameter name	Description	Range
level	The gain level applied	0 to 2
pan	stereo position	-1 (left) to 1 (right)

leslie

This is a decent approximation of a Leslie rotating speaker (for the "hammond" synth, but of course you can use it on anything, including samples). Real Leslie speakers have two switchable settings. Use a slow speed of 0.66 Hz for the "chorale" effect and a higher speed of 5.67 Hz for the "tremolo" effect.

Parameter name	Description	Range
speed	Rate of the speaker rotation (Hz)	0 to 100

lofi

This is experimental and possibly not very useful. Just occasionally it sounds good on something. Basically it attempts to emulate a bitcrusher by passing the audio through a stepped shaping function to reduce the "bit depth" but it doesn't quite sound like a bitcrusher. Note that low amplitude signals can completely disappear when passed through this. That's a feature, not a bug.

There are no parameters for this one.

mono_delay

Parameter name	Description	Range
delay	delay in seconds	0 to 1
pan	stereo pan position of the delays, negative to left, positive to right	-1 to 1
feedback	feedback amount, values close to 1 will go on forever!	0 to 1

overdrive

Parameter name	Description	Range
preGain	Gain before distortion is applied	typically 0.5 to 10
postGain	Gain after distortion is applied	typically 0.1 to 1
frequency	Center frequency of the bandpass filter (Hz)	typically around 1500 Hz
bandwidth	Bandwidth of the bandpass filter	0.1 to 100

pico_pebble

This is an attempt to model the Electroharmonix Small Stone phaser much used by Jean-Michel Jarre in Oxygene. Combined with the "synthstrings" synth it does a pretty passable job.

Parameter name	Description	Range
rate	rate of the phaser (Hz)	0.1 to 10
spread	extent of stereo effect	0 to 1
feedback	amount of feedback in the phaser network	0 to 1
depth	the depth of the phaser effect	0 to 1
resonance	set the resonance, larger number give a stronger effect	0 to 1

stereo_delay

Parameter name	Description	Range
leftDelay	left channel delay in seconds	0 to 1
rightDelay	left channel delay in seconds	0 to 1
spread	stereo spread of the left and right channels, 1 pans them hard left and hard right	0 to 1
feedback	feedback amount, values close to 1 will go on forever!	0 to 1

thick_phaser

Parameter name	Description	Range
rate	rate of the phaser (Hz)	0.1 to 10
spread	extent of stereo effect	0 to 1
feedback	amount of feedback in the phaser network	0 to 1
depth	the depth of the phaser effect	0 to 1
resonance	set the resonance, larger number give a stronger effect	0 to 1

tremolo

Parameter name	Description	Range
rate	rate of the tremolo effect (Hz)	0 to 100
spread	extent of stereo effect	0 to 1
depth	the depth of the tremolo effect	0 to 1
