## `gate split index switch threshold attack hold decay gaterange`
**TODO:** find good parameters
- switch (bool): 0..1, default 0
- threshold (dB): -70..12, default -70
- attack (ms): 0.1..500, default 30
- hold (ms): 5..3000, default 500
- decay (ms): 5..4000, default 1000
- gaterange (dB): -90..-20, default -90
## `detune split index detune mix output latency`
> A low-quality stereo pitch shifter for the sort of chorus and detune effects found on multi-effects hardware.
- detune (cents, left channel is lowered in pitch, right channel is raised): 0..1, default 0.2
- mix (wet/dry mix): 0..1, default 0.9
- output (level trim): 0..1, default 0.5
- latency (trade-off between latency and low-freq response): 0..1, default 0.5
other presets:
- stereo detune: 0.2 0.9 0.5 0.5
- out of tune: 0.8 0.7 0.5 0.5
## `overdrive split index drive muffle output`
> Possible uses include adding body to drum loops, fuzz guitar, and that 'standing outside a nightclub' sound. This plug does not simulate valve distortion, and any attempt to process organ sounds through it will be extremely unrewarding!
- drive (amount of distortion): 0..1, default 0
- muffle (gentle low-pass filter): 0..1, default 0
- output (level trim): 0..1, default 0.5
## `degrade split index headroom quant rate post_filt non_lin output`
> Sample quality reduction
**NOTE:** finding the right parameters is HARD for this plugin.
- headroom (peak clipping threshold): 0..1, default 0.8
- quant (bit depth, typically 8 or below for "telephone" quality): 0..1, default 0.5
- rate (sample rate): 0..1, default 0.65
- post_filt (low-pass filter to muffle the distortion): 0..1, default 0.9
- non_lin (additional harmonic distortion "thickening"): 0..1, default 0.58
- output: 0..1, default 0.5
## `repsycho split index tune fine decay thresh hold mix quality`
**NOTE:** HARD to find good parameters
- tune (coarse tune, semitones): 0..1, default 1
- fine (fine tune, cents): 0..1, default 1
- decay (adjust envelope of each trunk, a fast decay can be useful while setting up): 0..1, default 0.5
- thresh (trigger level to divide the input into chunks): 0..1, default 0.6
- hold (minimum chunk length): 0..1, default 0.45
- mix (mix original signal with output): 0..1, default 1
- quality (quality, bool. the high=1 setting uses smoother pitch-shifting and allows stereo): 0..1, default 0
## `talkbox split index wet dry carrier quality`
> High resolution vocoder
- wet: 0..1, default 0.5
- dry: 0..1, default 0
- carrier: 0..1, default 0
- quality: 0..1, default 1
