Sound.Tidal.MIDI.SynthParams

In general, synth parameters specify patterns of sounds, and patterns of effects on those sounds. These are the synthesis parameters you can use with the default Dirt synth:

Documentation

sound :: Pattern String -> ParamPattern

a pattern of strings representing sound sample names (required).

sound is a combination of the s and n parameters to allow specifying both sample name and sample variation in one:

d1 $ sound "bd:2 sn:0"

is essentially the same as:

d1 $ s "bd sn" # n "2 0"

grp :: [Param] -> Pattern String -> ParamPattern

group multiple params into one

accelerate :: Pattern Double -> ParamPattern

a pattern of numbers that speed up (or slow down) samples while they play.

bandf :: Pattern Double -> ParamPattern

a pattern of numbers from 0 to 1. Sets the center frequency of the band-pass filter.

bandq :: Pattern Double -> ParamPattern

a pattern of numbers from 0 to 1. Sets the q-factor of the band-pass filter.

begin :: Pattern Double -> ParamPattern

a pattern of numbers from 0 to 1. Skips the beginning of each sample, e.g. `0.25` to cut off the first quarter from each sample.

Using `begin "-1"` combined with `cut "-1"` means that when the sample cuts itself it will begin playback from where the previous one left off, so it will sound like one seamless sample. This allows you to apply a synth param across a long sample in a way similar to chop:

cps 0.5

d1 $ sound "breaks125*8"  begin "-1"  coarse "1 2 4 8 16 32 64 128"

This will play the breaks125 sample and apply the changing coarse parameter over the sample. Compare to:

d1 $ (chop 8 $ sounds "breaks125")  coarse "1 2 4 8 16 32 64 128"

which performs a similar effect, but due to differences in implementation sounds different.

channel :: Pattern Int -> ParamPattern

choose the physical channel the pattern is sent to, this is super dirt specific

coarse :: Pattern Int -> ParamPattern

fake-resampling, a pattern of numbers for lowering the sample rate, i.e. 1 for original 2 for half, 3 for a third and so on.

crush :: Pattern Double -> ParamPattern

bit crushing, a pattern of numbers from 1 (for drastic reduction in bit-depth) to 16 (for barely no reduction).

cut :: Pattern Int -> ParamPattern

In the style of classic drum-machines, cut will stop a playing sample as soon as another samples with in same cutgroup is to be played.

An example would be an open hi-hat followed by a closed one, essentially muting the open.

d1 $ stack [
  sound "bd",
  sound "~ [~ [ho:2 hc/2]]" # cut "1"
  ]

This will mute the open hi-hat every second cycle when the closed one is played.

Using cut with negative values will only cut the same sample. This is useful to cut very long samples

d1 $ sound "bev, [ho:3]" # cut "-1"

Using `cut "0"` is effectively _no_ cutgroup.

cutoff :: Pattern Double -> ParamPattern

a pattern of numbers from 0 to 1. Applies the cutoff frequency of the low-pass filter.

cutoffegint :: Pattern Double -> ParamPattern

delay :: Pattern Double -> ParamPattern

a pattern of numbers from 0 to 1. Sets the level of the delay signal.

delayfeedback :: Pattern Double -> ParamPattern

a pattern of numbers from 0 to 1. Sets the amount of delay feedback.

delaytime :: Pattern Double -> ParamPattern

a pattern of numbers from 0 to 1. Sets the length of the delay.

detune :: Pattern Double -> ParamPattern

dry :: Pattern Double -> ParamPattern

when set to `1` will disable all reverb for this pattern. See room and size for more information about reverb.

end :: Pattern Double -> ParamPattern

gain :: Pattern Double -> ParamPattern

a pattern of numbers that specify volume. Values less than 1 make the sound quieter. Values greater than 1 make the sound louder.

hcutoff :: Pattern Double -> ParamPattern

a pattern of numbers from 0 to 1. Applies the cutoff frequency of the high-pass filter.

hresonance :: Pattern Double -> ParamPattern

a pattern of numbers from 0 to 1. Applies the resonance of the high-pass filter.

loop :: Pattern Int -> ParamPattern

loops the sample (from begin to end) the specified number of times.

n :: Pattern Int -> ParamPattern

specifies the sample variation to be used

nudge :: Pattern Double -> ParamPattern

Pushes things forward (or backwards within built-in latency) in time. Allows for nice things like _swing_ feeling:

d1 $ stack [
  sound "bd bd/4",
  sound "hh(5,8)"
  ] # nudge "[0 0.04]*4"

Low values will give a more _human_ feeling, high values might result in quite the contrary.

offset :: Pattern Double -> ParamPattern

orbit :: Pattern Int -> ParamPattern

a pattern of numbers. An orbit is a global parameter context for patterns. Patterns with the same orbit will share hardware output bus offset and global effects, e.g. reverb and delay. The maximum number of orbits is specified in the superdirt startup, numbers higher than maximum will wrap around.

pan :: Pattern Double -> ParamPattern

a pattern of numbers between 0 and 1, from left to right (assuming stereo).

resonance :: Pattern Double -> ParamPattern

a pattern of numbers from 0 to 1. Specifies the resonance of the low-pass filter.

room :: Pattern Double -> ParamPattern

a pattern of numbers from 0 to 1. Sets the level of reverb.

shape :: Pattern Double -> ParamPattern

wave shaping distortion, a pattern of numbers from 0 for no distortion up to 1 for loads of distortion.

size :: Pattern Double -> ParamPattern

a pattern of numbers from 0 to 1. Sets the perceptual size (reverb time) of the room to be used in reverb.

speed :: Pattern Double -> ParamPattern

a pattern of numbers from 0 to 1, which changes the speed of sample playback, i.e. a cheap way of changing pitch

s :: Pattern String -> ParamPattern

a pattern of strings. Selects the sample to be played.

unit :: Pattern String -> ParamPattern

only accepts a value of "c". Used in conjunction with speed, it time-stretches a sample to fit in a cycle.

velocity :: Pattern Double -> ParamPattern

vowel :: Pattern String -> ParamPattern

formant filter to make things sound like vowels, a pattern of either a, e, i, o or u. Use a rest (`~`) for no effect.
