Fm graph

type Fm a = State St a Source #

data FmNode Source #

fmOsc' :: (Sig -> SE Sig) -> Sig -> Fm FmNode Source #

Creates fm node with generic wave.

fmOsc' wave modFreq

fmOsc :: Sig -> Fm FmNode Source #

Creates fm node with sine wave.

fmOsc modFreq

fmSig :: Sig -> Fm FmNode Source #

Creates fm node with signal generator (it's independent from the main frequency).

fmod :: FmNode -> [(Sig, FmNode)] -> Fm () Source #

fmOut :: Fm [(Sig, FmNode)] -> Sig -> SE [Sig] Source #

Renders Fm synth to function.

fmOut1 :: Fm FmNode -> Sig -> SE Sig Source #

Renders mono output.

fmOut2 :: Fm (FmNode, FmNode) -> Sig -> SE Sig2 Source #

Renders stereo output.
