This allows to move or copy whole sections of the timline (everything
you hear) to a differnt position on the timeline.
NB. Markers and tempo-map are not yet moved, and interpolated MIDI
events are lost.
Tempo Map updates can change a region's position/length, in which case
region-automation may follow the region, and DiskReader:: playlist_ranges_moved
will save additional undo information.
These MementoCommand(s) need to be included in the undo operation.
Import via Drag/Drop previously worked by selecting a track,
and then importing to the selected track.
This approach fails when the selected track is in a track-group,
and selecting the track also selects other tracks of different type.
Now the track to drop onto is passed directly passed through to
::finish_bringing_in_material as existing_track.
This is really just an example synth (sine wave + fixed
basic ASR envelope).
Note: existing sessions using the synth are not affected, the
script is saved with the session.
Some music using square waves can inadvertently be interpreted as valid
LTC frame. However the encoded data is not a valid timecode, which can
lead huge A/V offsets, or other issues.
Most wscripts use
#!/usr/bin/env python
Use that consistently.
The wscripts are not executed directly and do not need the shebang path,
but it might guide editors and other tools to recognize the files as
being Python-ish.
