this solves the oft-recurring problem where we assign
a beat-count of '3' or '7' because minipm mis-detected the tempo,
and that situation is vanishingly rare. it's better to assume 4 or 8
the user always has the option to change the number of beats (and
therefore the detected tempo) manually, for those clips that are
in a different time signature. but minibpm cannot be expected
to help us there.
NOTE: this is a fallback to make things 'just work' lacking any other context.
* if the tempo is detected in the filename, we use that instead
* clips that were recorded to the timeline use that bpm+timesig
* in the future we can use file-metadata (acidized wave?) instead
* this is audio-only: midi files can have an embedded timesignature
but... given no other information, experience says the vast majority
of downloaded/purchased clips will be 1,2 or 4 bars at 4/4.
omega can be computed from Beat or superclock duration. This gives rise to
different units for omega, and we must use the correct value in a given
context.
This commit also changes the way that the audio time omega is computed during
TempoMap::reset_starting_at()
Rampable only existed to provide exclusive access to ::set_end() for the
TempoMap. More idiomatic C++ but now that _type has also gone away, so has
::set_ramped() and it really was not worth keeping it around.
Ramped/Constant is really a function of start/end note_types_per_minute. Having
a separate member is really just caching it and leads to errors or risk thereof.
MidiBuffer::read_from() clears the buffer, so events were not
accumulated into the delay-buffer.
This also includes a small optimization and comments for the
variable delayline.
* when you copy a Range into a playlist, the playlist's 'timeline' should
begin at the start of the selected Range. Regions should retain the
offset they had from the Range's start.
* this fixes the Draw tool when adding notes; if you tried to draw in
a region with a trimmed front, the note would not get added in the correct
location
syntax for beginning and ending a diff command is:
"new_diff_command" -> "apply_diff_command"
syntax for applying a diff_command is:
"_as_commit" : Begins and Commits a standalone undo Command
"_as_subcommand" : adds to undo but does not Begin or Commit a Command
"_only" : (new) applies the note_diff but does not have any effect on undo
This is useful after a freewheel export, where a realtime-stop
is called, but the actual Locate/MustStop event is only processed
later. Once the session switches back to normal processing after
export the transport is still rolling, TSFM schedules a de-click
locate. This may play some remaining audio.
This new API allows to hard stop the transport, without going
via any session-events and process_with_events. It is intended to
be called from the freewheel process-callback in the last export
cycle.
The idea is to run a plugin outside the process graph, and provide
its I/O as port (much like an external JACK app).
The intended use-case is NDI (provide additional I/O), but it could
also be useful for other cases.
