Iterating over a const Midi-Sequence calls Evoral::Sequence::set_event(),
which in turn used Evoral::Event::operator=() which always created
a new event-ID (create copy of the event).
Issues fixed:
- Saving *unmodified* MIDI produced new event-IDs on every save;
files changed with every save. - greetings to Deva.
- all [GUI] operations that use IDs to refer to notes e.g. undo.
invalid undo-history.
Also clarify assignment operator name. Prefer explicit assign() over =.
- probably fixes a lot of cases where note ids are assumed to be
unique (they weren't for copies and some others).
- wrong branch, but it needs testing.
This avoids stuck notes if active notes are edited, but without stopping all
active notes in the region on any edit as before.
This implementation injects note ons in places that aren't actually note
starts. Depending on how percussive the instrument is, this may not be
desired. In the future, an option for this would be an improvement, but there
are other places where "start notes in the middle" is a reasonable option. I
think that should be handled universally if we're to do it at all, so not
considering it a part of this fix for now.
This lets us get a more explicit handle on time conversions, and is the main
step towards using actual beat:tick time and getting away from floating point
precision problems.
Vimmers, try let c_space_errors = 1 in your .vimrc to highlight this kind of stuff in red. I don't know the emacs equivalent...

Use iterator interface of Sequence to read events in a MIDISource rather than Sequence::read, avoiding timestamp confusion.
Disable no longer useful Sequence::read.

- Separate SMF::open and SMF::create, more powerful interface for both.
- Correctly handle note ons with velocity 0 as note offs in sequence.
- Use SMF (i.e. libsmf) for MIDI import

(Only change: use #include "" instead of #include <> for local include paths).

Sane event type interface between evoral and libardour (no more shared magic numbers).
Cleanup Evoral::Sequence iterator, fix bugs, probably introduce new ones.
Move MIDI specific event functions to Evoral::MIDIEvent (is-a Evoral::Event).

Anything related to the storage of events/values over a range of time lives in evoral.
This includes MidiModel (Evoral::Sequence) and automation data (AutomationList (Evoral::ControlList),
Automatable (Evoral::ControlSet), etc).
