- this helps where tempo and meter have a somewhat circular
dependency.
MetricSection now has a musical position expressed in beats (a double).
MeterSection still has a bbt, but it really isn't needed as we have
enough information to discover the number of bars at a given beat without it.
TempoSection now has a hack to enable loading of legacy sessions, which will
ultimately be a lot cleaner than the current code.
Removing bars from tempo sections also allows us to place them
at arbitrary frames (implemented here).
Replaces the list of points in TempoMap with TempoSection functions, which
compute tempo-at or tick-at time relative to tempo section start.
TempoMap consults them additively to determine things like bbt_time(),
frame_time() get_grid() etc.
This has a marked effect on scrolling speed along with the code simplification
in the places it has been attempted.
Several things are broken here.
Currently every ramp except the last one is an exponential ramp. this may
be simple to fix :).
Mouse-over midi grid doesn't match mouse click grid. should also be simple.
Many things seem to work, but their accuracy should be in question until
each area has been addressed.
Moving the mouse over another region's gain line changed
clicked_regionview. clicked_regionview is used along with range-time
when initiating an AutomationRangeDrag.
Too many users report they import their first tracks and can't find them.
Previous default was "at file timestamp". If a file has no timestamp,
the import dialog shows "00:00:00:00" but in absence of a timestamp,
Editor::add_sources() first checks target tracks and adds add it after
the last region, then falls back to use preferred edit position as
insert point.
In the rare case where a file has timestamps it may show up a few hours
in the future.
conclusion: import-at-timestamp is not a good default.
* pressing Esc or WM close button did not cancel import thread
* proper Abort does not wait for import thread either
It was possible to launch a 2nd (and Nth) import thread, all sharing
the Editor's ImportStatus data-structure, all having the same
registered thread-name and same thread-pool name. Plenty of room for
crashes.
opening a recent session from a session can result in: Editor::constructed
and session_loaded() being true. A partial instant_save can occur (not
to mention: invalid XMLnode iterators)
