amp: | The amplitude of the sound. Typically a value between 0 and 1. Higher amplitudes may be used, but won't make the sound louder, they 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
pre_amp: | Amplitude multiplier which takes place immediately before any internal FX such as the low pass filter, compressor or pitch modification. Use this opt if you want to overload the compressor. Default: 1 must be zero or greater May be changed whilst playing
pan: | Position of sound in stereo. With headphones on, this means how much of the sound is in the left ear, and how much is in the right ear. With a value of -1, the sound is completely in the left ear, a value of 0 puts the sound equally in both ears and a value of 1 puts the sound in the right ear. Values in between -1 and 1 move the sound accordingly. Default: 0 must be a value between -1 and 1 inclusively May be changed whilst playing
attack: | Duration of the attack phase of the envelope. Default: 0 must be zero or greater
decay: | Duration of the decay phase of the envelope. Default: 0 must be zero or greater

release: | Duration of the release phase of the envelope. Default: 0 must be zero or greater
lpf: | Low pass filter cutoff value. A MIDI note representing the highest frequencies allowed to be present in the sound.

rate: | Rate with which to play back - default is 1. Playing the sample at rate 2 will play it back at double the normal speed. This will have the effect of doubling the frequencies in the sample and halving the playback time. Use rates lower than 1 to slow the sample down. Negative rates will play the sample in reverse. Default: 1 must not be zero
start: | A fraction (between 0 and 1) representing where in the sample to start playback. 1 represents the end of the sample, 0.5 half-way through etc. Default: 0 must be a value between 0 and 1 inclusively
finish: | A fraction (between 0 and 1) representing where in the sample to finish playback. 1 represents the end of the sample, 0.5 half-way through etc. Default: 1 must be a value between 0 and 1 inclusively
norm: | Normalise the audio (make quieter parts of the sample louder and louder parts quieter) - this is similar to the normaliser FX. This may emphasise any clicks caused by clipping. Default: 0 must be one of the following values: [0, 1]
pitch: | Pitch adjustment in semitones. 1 is up a semitone, 12 is up an octave, -12 is down an octave etc. Maximum upper limit of 24 (up 2 octaves). Lower limit of -72 (down 6 octaves). Decimal numbers can be used for fine tuning. Default: 0 must be a value greater than or equal to -72,must be a value less than or equal to 24 May be changed whilst playing
window_size: | Pitch shift works by chopping the input into tiny slices, then playing these slices at a higher or lower rate. If we make the slices small enough and overlap them, it sounds like the original sound with the pitch changed. The window_size is the length of the slices and is measured in seconds. It needs to be around 0.2 (200ms) or greater for pitched sounds like guitar or bass, and needs to be around 0.02 (20ms) or lower for percussive sounds like drum loops. You can experiment with this to get the best sound for your input. Default: 0.2 must be a value greater than 5.0e-05 May be changed whilst playing
pitch_dis: | Pitch dispersion - how much random variation in pitch to add. Using a low value like 0.001 can help to "soften up" the metallic sounds, especially on drum loops. To be really technical, pitch_dispersion is the maximum random deviation of the pitch from the pitch ratio (which is set by the pitch param) Default: 0.0 must be a value greater than or equal to 0 May be changed whilst playing
time_dis: | Time dispersion - how much random delay before playing each grain (measured in seconds). Again, low values here like 0.001 can help to soften up metallic sounds introduced by the effect. Large values are also fun as they can make soundscapes and textures from the input, although you will most likely lose the rhythm of the original. NB - This won't have an effect if it's larger than window_size. Default: 0.0 must be a value greater than or equal to 0 May be changed whilst playing
compress: | Enable the compressor. This sits at the end of the internal FX chain immediately before the `amp:` opt. Therefore to drive the compressor use the `pre_amp:` opt which will amplify the signal before it hits any internal FX. The compressor compresses the dynamic range of the incoming signal. Equivalent to automatically turning the amp down when the signal gets too loud and then back up again when it's quiet. Useful for ensuring the containing signal doesn't overwhelm other aspects of the sound. Also a general purpose hard-knee dynamic range processor which can be tuned via the opts to both expand and compress the signal. Default: 0 must be one of the following values: [0, 1]
threshold: | Threshold value determining the break point between slope_below and slope_above. Only valid if the compressor is enabled by turning on the comp: opt. Default: 0.2 must be zero or greater May be changed whilst playing
clamp_time: | Time taken for the amplitude adjustments to kick in fully (in seconds). This is usually pretty small (not much more than 10 milliseconds). Also known as the time of the attack phase. Only valid if the compressor is enabled by turning on the comp: opt. Default: 0.01 must be zero or greater May be changed whilst playing
slope_above: | Slope of the amplitude curve above the threshold. A value of 1 means that the output of signals with amplitude above the threshold will be unaffected. Greater values will magnify and smaller values will attenuate the signal. Only valid if the compressor is enabled by turning on the comp: opt. Default: 0.5 May be changed whilst playing
slope_below: | Slope of the amplitude curve below the threshold. A value of 1 means that the output of signals with amplitude below the threshold will be unaffected. Greater values will magnify and smaller values will attenuate the signal. Only valid if the compressor is enabled by turning on the comp: opt. Default: 1 May be changed whilst playing
relax_time: | Time taken for the amplitude adjustments to be released. Usually a little longer than clamp_time. If both times are too short, you can get some (possibly unwanted) artefacts. Also known as the time of the release phase. Only valid if the compressor is enabled by turning on the comp: opt. Default: 0.01 must be zero or greater May be changed whilst playing
