§mseq_core

Core framework for building custom MIDI sequencers.

mseq_core provides the foundational traits and utilities needed to implement your own MIDI sequencer, with a focus on portability and modularity.

This crate is built with #![no_std], making it suitable for embedded platforms as well as standard operating systems.

To create a custom sequencer, you typically:

Implement the Conductor trait to define your sequencer’s control logic.
Define one or more tracks by either:
- Implementing the Track trait for custom behavior.
- Instantiating DeteTrack for deterministic, looping patterns.

For OS-based systems, use the mseq crate — a reference implementation of mseq_core for standard platforms.
For embedded development (e.g., STM32F4), see the mseq_embedded repository, which provides an STM32-specific integration of mseq_core.

Context: An object of type Context is passed to the user’s Conductor at each clock tick via the Conductor::update method. It provides a high-level interface to send system MIDI messages and modify system parameters.
DeteTrack: A deterministic track implementation.
MidiController: Provides a reusable MIDI interface and core logic across different platforms.
MidiNote: Note that can be sent through a MIDI message.

Instruction: Represents instructions that can be interpreted and processed by the MidiController.
MidiMessage: Represents a parsed MIDI instruction.
Note: Represents 1 note of the chromatic scale.

param_value: Performs a linear conversion from [0.0, 1.0] to [0, 127]. If v is smaller than 0.0 return 0. If v is greater than 1.0 return 127. The main purpose of this function is to be used with MIDI control changes (CC).
