Module engine 

Control and event mapping Control and automation subsystem.

Provides event mapping (MIDI/OSC → parameters), automaton-based modulation (LFO, envelopes), and a two-thread model with lock-free queues for control → signal communication.

Structs

Mapping

A complete mapping from an input event to a target parameter, with a value transform.

NoAction

A unit action for automatons that need no external action per step.

OscSurfaceEntry

A single entry in an OSC control surface, binding an OSC path to an event pattern.

Servo

Bridges an automaton to a graph parameter, stepping on every clock tick and sending control commands to the signal graph.

Target

The destination of an event mapping: a specific parameter on a specific graph node.

Enums

ControlEvent

Hardware control event from a physical interface (knob, button, fader, etc.).

EventPattern

A pattern for matching controller events.

MidiNoteKind

What aspect of a MIDI note event to extract for mapping.

MidiTransportKind

MIDI transport state.

ParameterMapping

Transfer function for mapping raw automaton output [0,1] to parameter space.

Transform

Transfer function applied to a normalized [0,1] value before scaling to parameter range.

Traits

Automaton

Core trait for automatons — stateful signal generators that advance per step.

Module

Unified interface for sensor and control modules (MIDI hubs, OSC servers, etc.).

Functions

midi_cc

Convenience constructor for a MIDI control change mapping.

midi_note

Convenience constructor for a MIDI note mapping.

osc_address

Convenience constructor for an OSC address mapping.

Type Aliases

BoxedModule

Type-erased, heap-allocated reference to any module.

OscSurface

A list of OSC address → event mappings forming a control surface layout.

Time

Time in seconds, used for automaton clocks and timekeeping.
