2020-04-07use shared_ptr to manage backend port lifetimes (Pulse,ALSA,Dummy,JACK)Paul Davis
JACK is not yet finished. Changes also include minor reformatting and a spelling correction (latecies to latencies)
2019-11-06fix unconditional note resolution during DiskReader::realtime_locate()Paul Davis
When looping, we do not want to resolve notes at the end of the loop via ::realtime_locate() - ::get_midi_playback() has already taken care of this. But when not looping, we need this. So, add an argument to tell all interested parties whether the locate is for a loop end or not

2018-11-26Fix various issues when the engine disconnects:Robin Gareus
Previously Port::PortDrop was never handled. The signal was disconnected directly when the connection is re-used by Port::PortSignalDrop. Ports::drop() was not called when the engine was stopped or disconnected, and port-handles were not invalidated. This lead to crashes whenever a port-related operation was performed while the engine was stopped. e.g. adding/removing tracks or plugins (latency recompute, notify port-engine) and various other operations.

waf (as it only gets generated when building with waf) When building with MSVC this was getting #included in a few places which had the effect of making my session files get generated in a very old format.
2017-11-04Add some notes for future optimizations (and prepare API)Robin Gareus
2017-10-29Remove unused per-port buffer offsetRobin Gareus
2017-10-29Move vari-speed into backend (resample ports)Robin Gareus
Previously Ardour used a /local/ per track vari-speed mechanism. Now that the disk-reader is a latency-compensated processor, the speed of each disk-reader would need to be maintained locally, offset by each disk-reader's output latency. Furthermore each disk-reader may produce a different number of samples, depending on its global alignment. This commit introduces port-data resampling directly at the engine-level: Up/down-sample all input ports at the beginning, and down/up-sample output port-data using the inverse ratio at the end of the session's process cycle. The session itself is unaware of the speed-change, and only needs to handle transport speeds {-1, 0, +1}. This also allows for aligned cue-monitoring and vari-speed recording, and also pitch-shifts synthesized MIDI along.
