* prevent duplicate names when pulling-in external sources
* drop "origin" after including external sources
* don't include unused playlists
(they may reference sources that are not included)
* likewise exclude unused regions
* Processor implement get_state(), classes derived from Processor
implement protected ::state() -- as documented in processor.h
* likewise for Route, Track: make ::state() a protected interface
* removal of "full_state", use explicit "template_save"
* use RAII/Unwind to skip saving automation-state
- Fix API call to add region(midi_region) -- set count to "1"
- Forward DataRecorded() signal
- remove botched merge/rebase"
a4a87f56 accidentally brought back code from old-destructive API
which was removed in af103cf3 and 08c13007
There is no per track NonLayered record mode anymore, it's session global.
- set can_record correctly to not accidentally clear last capture sources
for cont'd recording (toggle track's rec-arm)
* use start/end frame
* differentiate nframes and disk_samples_to_consume
* add global Port::port_offset () when writing data.
* add a note about b0rked vari-speed ..
Immediate events are used for MIDI-Panic and to inject GUI generated
events e.g. patch-changes, note-events from the track-header
(scroomer-keyboard) and patch-change audition.
Current behavior:
- snapshot copy immediate events from ringbuffer into a buffer at
the beginning of each the cycle.
- Inject immediate events into input-buffer directly after reading the input
- process "normally"
- pass immediate event-buffer to disk-writer, so it can skip them
(don't write immediate events to disk)
- if the Route is not monitoring input: clear buffer before disk-reader
and re-inject (original) immediate events after the disk-reader
- immediate events process normally and are also sent to outputs.
This moves common code (get and fill buffers) into ::passthru()
and renames ::passthru() to ::run_route().
passthru_silence() is no longer used (it was only needed A5 style
Track::no_roll_unlocked for no-roll + disk-monitoring)
Currently ::roll() may actually be a ::no_roll() under some circumstances.
This can also happen during count-in:
transport_stopped () == transport_rolling()
and during latency-preroll:
Global session-transport speed != 0, some tracks already roll,
read data from disk and feed latent plugins.
but other non-latent tracks or busses don't roll and still have to
behave like the switch from no_roll() to roll() has not yet happened.
This changes the game WRT to monitoring as well, previously, Route:roll()
called Route::no_roll_unlocked () for conditions outlined above.
Now Track::no_roll_unlocked is called and in some cases wrongly clears
the buffers before the signal hits the disk-writer. (more work is needed
related to 61f8e53b)
On the upside this also fixes an issue with MidiTrack::no_roll not keeping
a lock while pushing data into the step-edit-ringbuffer.
This is also a step towards consolidating all entry points:
::roll(), ::no_roll(), ::silent_roll() in the Route class.
Individual Routes cannot split the process-cycle in no_roll(); roll()
by themselves. Each of the calls will flush output buffers (and offset
port-buffers). If a route feeds another route the inputs of the other
route will only see partial data.
