Description

Synth Definitions in SuperCollider are how you define the way synths should sound -- you describe parameters and a graph of sound generators, add them to the server with defineSD, and then create instances of the Synth Definition (called "synths"), which each play separately. You can set parameters of the synth at any time while they're playing

Usually, you shouldn't be making SynthDefs explicitly -- there's a state monad SDBody which lets you construct synthdefs like so:

  test :: SynthDef
  test = sd (0 ::I "note") $ do
     s <- 0.1 ~* sinOsc (freq_ $ midiCPS (V::V "note"))
     out 0 [s, s]
  

You then optionally explicitly send the synth definition to the SC server with

>>> defineSD test

You then create a synth from the synthdef like:

>>> s <- synth test (45 ::I "note")

This returns a NodeId which is a reference to the synth, which you can use to e.g. change the params of the running synth with e.g.

>>> set s (38 ::I "note")

Then you can free it (stop its playing) with

>>> free s

(If you want interop with SClang, use "sdNamed" and "synthNamed")

Synopsis

Synth actions

Synth Definition Construction

data SynthDef args Source #

Internal representation of Synth Definitions. Usually, use sd instead of making these by hand.

This representation (especially _sdUGens) might change in the future.

Constructors

SynthDef 

Instances

Show (SynthDef args) Source # 

Methods

showsPrec :: Int -> SynthDef args -> ShowS #

show :: SynthDef args -> String #

showList :: [SynthDef args] -> ShowS #

(~) [Symbol] a args => ToSig (SDBody' a Signal) args Source # 

Methods

toSig :: SDBody' a Signal -> SDBody' args Signal Source #

data UGen Source #

Representation of Unit Generators. You usually won't be creating these by hand, but instead using things from the library in UGens

Instances

Eq UGen Source # 

Methods

(==) :: UGen -> UGen -> Bool #

(/=) :: UGen -> UGen -> Bool #

Show UGen Source # 

Methods

showsPrec :: Int -> UGen -> ShowS #

show :: UGen -> String #

showList :: [UGen] -> ShowS #

addMonoUGen :: UGen -> SDBody' args Signal Source #

Add a unit generator with one output

addPolyUGen :: UGen -> SDBody' args [Signal] Source #

Polyphonic -- returns a list of Signals. In the future this might be a tuple instead of a list

class ToSig s args where Source #

Don't define other instances of this! (Unless you know what you're doing) Instance resolution could get screwed up.

Minimal complete definition

toSig

Methods

toSig :: s -> SDBody' args Signal Source #

Instances

(Num n, Real n) => ToSig n args Source #

For Constant (Float) values

Methods

toSig :: n -> SDBody' args Signal Source #

ToSig Signal args Source # 

Methods

toSig :: Signal -> SDBody' args Signal Source #

ToSig BufferId args Source # 

Methods

toSig :: BufferId -> SDBody' args Signal Source #

(KnownSymbol a, Subset ((:) Symbol a ([] Symbol)) args) => ToSig (Variable a) args Source # 

Methods

toSig :: Variable a -> SDBody' args Signal Source #

(~) [Symbol] a args => ToSig (SDBody' a Signal) args Source # 

Methods

toSig :: SDBody' a Signal -> SDBody' args Signal Source #

data Signal Source #

Instances

Eq Signal Source # 

Methods

(==) :: Signal -> Signal -> Bool #

(/=) :: Signal -> Signal -> Bool #

Show Signal Source # 
ToSig Signal args Source # 

Methods

toSig :: Signal -> SDBody' args Signal Source #

(~) [Symbol] a args => ToSig (SDBody' a Signal) args Source # 

Methods

toSig :: SDBody' a Signal -> SDBody' args Signal Source #

sd :: VarList argList => argList -> SDBody' (InnerVars argList) [Signal] -> SynthDef (InnerVars argList) Source #

Define a Synth Definition

sdNamed :: VarList argList => String -> argList -> SDBody' (InnerVars argList) [Signal] -> SynthDef (InnerVars argList) Source #

Define a Synth Definition and give it a name you can refer to from e.g. sclang

(?) :: SDBody' args Signal -> CalculationRate -> SDBody' args Signal Source #

Set the calculation rate of a UGen

e.g.

play $ do
   s0 <- 1 ~+ (lfSaw (freq_ 1) ? KR)
   s1 <- 0.1 ~* lfSaw (freq_ $ 220 ~* s0)
   out 0 [s1, s1]

Mnemonic: "?" is like thinking

In the future, the representation of calculation rates may change

data DoneAction Source #

Action to take with a UGen when it's finished

This representation will change in the future

execState #

Arguments

:: State s a

state-passing computation to execute

-> s

initial value

-> s

final state

Evaluate a state computation with the given initial state and return the final state, discarding the final value.

Built-in Unit Generator Operations

data UnaryOp Source #

Unary signal operations. Many of these have functions so you don't need to use this internal representation (e.g. Neg has neg, etc).

This type might not be exposed in the future.

There's a bug in some SC versions where .bitNot isn't implemented correctly. Vivid backfills it with a fix, so you can use BitNot with any SC version

data BinaryOp Source #

Binary signal operations. For the simple ones (like Add, Mul, etc.), there are functions (like ~+, ~*, etc.) that wrap them up so you don't have to make a ugen for them yourself.

In the future these may not be exported -- we'll just have functions for all of them.

makeSynthDef :: VarList argList => SDName -> argList -> SDBody' (InnerVars argList) [Signal] -> SynthDef (InnerVars argList) Source #

shrinkSDArgs :: Subset new old => SynthDef old -> SynthDef new Source #

Like shrinkNodeArgs but for SynthDefs

Orphan instances

Hashable (SynthDef a) Source #

This is the hash of the UGen graph and params, but not the name! So (re)naming a SynthDef will not change its hash.

Methods

hashWithSalt :: Int -> SynthDef a -> Int #

hash :: SynthDef a -> Int #
