Function control_output_port 

pub fn control_output_port(name: &str) -> NodePort

Helper to create a control output port

Use this for ParamCompute MODs that generate control signals (LFO, envelope, etc.)

Note: No control_input helper

All parameters are implicitly controllable - any parameter can receive modulation from a control-output port without explicit declaration. The target parameter is selected via UI (ControlTargetSelector widget), not hardcoded in the MOD.

Example

let port = control_output_port("lfo_out");
