Sound.SC3.UGen.Graph.Transform

Transformations over Graph structure.

Lift constants

constant_to_control :: NodeId -> Node -> (NodeId, Node)

Transform NodeC to NodeK, id for other Node types.

let r = (NodeK 8 KR Nothing "k_8" 0.1 K_KR,9)
in constant_to_control 8 (NodeC 0 0.1) == r

from_port_node_err :: Graph -> FromPort -> Node

Erroring variant of from_port_node.

c_lift_from_port :: Graph -> NodeId -> FromPort -> (NodeId, Either FromPort Node)

If the FromPort is a constant generate a control Node, else retain FromPort.

c_lift_inputs :: Graph -> NodeId -> [FromPort] -> (NodeId, [FromPort], [Node])

Lift a set of NodeU inputs from constants to controls. The result triple gives the incremented NodeId, the transformed FromPort list, and the list of newly minted control Nodes.

c_lift_ugen :: Graph -> NodeId -> Node -> (NodeId, Node, [Node])

c_lift_ugens :: Graph -> NodeId -> [Node] -> (NodeId, [Node], [Node])

lift_constants :: Graph -> Graph
