This needs further work:
Type-1 SMF are always
"One [Ardour] track per [MIDI] track"
Only type-0 SMF have the option
"One [Ardour] track per [MIDI] channel"
and
"One [Ardour] track per [MIDI] file"
This is ambiguous with multi-channel audio or multiple selection,
mixed audio+midi and worse with mixed type0/1 .mid selection.
This calls for a dedicated dropdown to select MIDI Import Disposition
for type-0 SMF.
I used the Widget::on_hide method in the ExportFileDialog to defer the saving
of changes in state of the analysis and soundcloud-upload checkboxes as it was
not possible to save the format xml state directly from the
ToggleButton::toggled() signal as it created a recursive loop and also to
prevent saving the state more than once.
Even though the ExportProfileManager::FormatListChanged signal is no longer
emitted when saving format state and the crash no longer occurs without this
change. I think it is worth saving explicitily from in the toggle callbacks to
reduce the complexity of understanding what is taking place and when even if it
is less efficient.
There is definitely more opportunity for refactoring and redesign.
This is not caused by commit_reversible_command, but because
NoteDrag::total_dx calls Evoral::Note<Evoral::Beats>::time()
with invalid MIDI note (deleted).
This should be a proper fix for bug #7003, now that I've spent a bit more time
reading the code. The options are now stored as part of the export format
state.
There were two issues:
The first is that TrimDrag::aborted was calling TrimDrag::finished with a null
GdkEvent which caused a segfault when dereferencing. So avoid that by passing
in a dummy event as we are just going to undo the operation in the next step
anyway so it shouldn't matter if it is valid(AFAICT).
The other is that TrimDrag:aborted was calling Editor::undo() which was in turn
calling TrimDrag::aborted leading to infinite recursion and stack overflow.
Calling Session::undo() directly seems to avoid that issue.
This fix feels like a bit of a hack...but it seems to work and is better than a
crash.
