When a non-existent file-path is given, GTK falls back to show the
containing folder and automatically goes up to parent folders until
the root.
This removes the explicit file/folder check and delegates the
behavior to GTK, allowing to set a folder for a non-existent file.
Loading a session includes setting the sync-source, this is queued
to happen during process(), which may or may not be while Session::Loading
is still set.
This change only catches the common case: internal transport, no slave.
This fixes an issue with the session being marked as dirty without
any actual change. Also this method indirectly called during session-load
when the UI state is restored, a potential race with "Session::Loading"
being unset.
We no longer assume that Snap always uses the visible ruler lines.
If you want to snap to the grid, and ignore the users zoom scale, use SnapPref::SnapToGrid_Unscaled
This fixes 2 (known) oversights: "snap region(s) to grid" and "regions whose start are left of the canvas edge".
config_map.erase() is only called in ExportHandler::finish_timespan().
When an export fails (throw) or is aborted, the export-handler's
config remains as is and the next export will run it again.
The export-handler is global, per session and
ExportHandler::add_export_config() only ever inserts or ignores insert.
This is in preparation to fix:
1) export to invalid path -> fail, error is thrown
2) correct path -> new config is inserted in the map
3) try to export again, first runs the not-completed export from (1)
-> constant errors.
Some MIDNAM files use Patch-Banks that do *not* have a common midi bank
(CC0, CC32) but the Patchbank is instead just a collection of patches.
There may be more than 127 patches in a patch-bank and each of those
may be in a different midi-bank (e.g. Roland SC-88 Pro).
Midnams like these are now properly supported via dropdowns (in the
patch add/modify dialog and timeline), but ignored by the grid
(patch-widget). More work is needed.
