01 Getting Started

• Terminology

MIDI is full of domain specific vocabulary. And MIDI-Perl is full of its own! For instance: track, event, note, duration, control change, etc. A "Track" is a thing in MIDI::Simple, but we will use the term generically to refer to a sequence of notes added to the score on a specific channel. An "Event" is a granular aspect of the score, with which we will not concern ourselves. "Note" is another tricky term. It is used both to refer to the pitch and duration. For us, these two things are considered separately. A "control change" is a message you give to the score to set things like reverb or chorus.
