Documentation

class HasMidi a where

Class of types that can be converted to MIDI.

Numeric types are interpreted as notes with a default velocity, pairs are interpreted as (pitch, velocity) pairs.

Minimal definition: getMidi. Given getMidiScore, getMidi can be implemented as getMidiScore . return.

Methods

getMidi :: a -> Score Message

Convert a value to a MIDI score. Typically, generates an on event using note followed by an optional off event.

getMidiScore :: Score a -> Score Message

Convert a score to a MIDI score. The default definition can be overriden for efficiency.
