pan

Type: pan :: Pattern Double -> ControlPattern

pan turns a number pattern (ranging from 0 to 1) into a control pattern that specifies the audio channel. In a 2-channel setup, a value of 0 pans the audio hard left and a value of 1 pans the audio hard right. The default value is 0.5, which produces full volume on both channels.

d1 $ sound "bd feel odx drum" # pan "0 1 0.25 0.75"

d1 $ sound "bd*16" # pan (slow 3 $ sine)
