Bounce (Session::write_one_track) uses bounce_chunk_size = 8192
to process data. This requires gain_automation_buffer, and
scratch buffers that can hold 8k samples.
Previously the buffers were not allocated when bounding MIDI
(no synth), leading to a crash when automation was used.
Previously there was only a PostDisconnect() signal.
When a port connection is made directly e.g. recorder_ui.cc
r->input()->audio(..)->connect(...), or when connecting
using an external jack control app, Ardour::IO is not informed.
no IOChange::ConnectionsChanged signal is emitted and
Track::set_align_choice_from_io() is not called. This leads to
incorrec capture alignment.
To minimize signal emission the static global PostDisconnect
is changed into a per port ConnectedOrDisconnected signal.
IOs subscribes to signals from owned ports only.
Rely on previously collected I/O port-list, skip expensive call
to get_physical_inputs() and rely on RCU port list alone.
Also skip port_is_mine() test in optimized builds.
* You can now show a selector for each track, rather than one global dialog
* Removed the 'cancel' button: it was too easy to unintentionally revert your selection
* Correctly sort and name new playlists when they are added or renamed from the P menu
* Fix problem where list contents disappeared when changing desktops (on_unmap_event)
* avoid memory allocation (remove std:set<>&)
* skip nested loop using port-names as IDs
However this adds a bit of extra cost in case input ports are
monitored: get_port_by_name() and get_buffer()
glib atomic operations include a complete act as a full
compiler and (where appropriate) hardware memory barrier.
std::atomic<> allows dedicated acquire and release barrier
semantics which are not available with glib.
* Add an option to use a playlist without stealing its ownership. (libardour)
* Tracks emit PlaylistAdded when a new playlist is created either by copying or by creating a new empty pl
* no version-check should be necessary because when opening an old session,
playlists can be looked-up by discrete names and will be tracked by ID thereafter
