Type Alias: NoteSource
type NoteSource = string;
Defined in: dom/src/piano/index.ts:19
What asked for a note to sound.
A note stops only once everything that asked for it has let go, so two fingers on one key, or a key held by both the mouse and a MIDI keyboard, behave the way they look.
Pointers use pointer:<pointerId>; everything else names its own source.
