/**
* The MidiData class represents a list of @ref MidiEvents in time order.
* It is an abstract base class, notably implemented by @ref Phrase and
* @ref PhraseEdit.
*
* MidiData objects are not designed to be editable. Only the
* @ref PhraseEdit class defines an editable MidiData object.
*
* MidiData does not implement the @ref Playable interface. This is for a
* very good reason: more than one @ref Part may be using a given
* @ref Phrase at the same time. The @ref Playable interface doesn't
* provide an 'iterator' type so only one client can play a @ref Playable
* at once. Therefore MidiData doesn't implement @ref Playable. It's a
* piece of cake to use, anyway.
