Archiving creates a dedicated mono file for each Source.
When the original session has (embedded) stereo files, the
channel needs to be temporarily set to 0.
introducing a new time signature that uses non-quarter notes as the denominator
will move the beat position a given BBT time (since the middle "B" of BBT
refers to "beats" given by the denominator, not quarters).
This issue was introduced in f3423b8a77, which assumed that
number of input channels matches the number of outputs.
With flexible I/O this is not necessarily the case.
This fixes#9106, along with the previous commit.
If Route::configure_processors fails at session start,
meters are not configured (#9106), leading to a crash when
::run() is called (insufficient peak/max/midi buffers).
Previously the flag was not honored. AudioSource::write() calls
-> SndFileSource::write_unlocked()
-> SndFileSource::nondestructive_write_unlocked() which calls
-> AudioSource::compute_and_write_peaks
This produced "cannot open _peakpath" messages during
session-archive FLAC encoding. Likewise closing an audio file
calls touch_peakfile(). Although this simply failed silently.
Keep file-system paths and PBD::Searchpath mostly separate.
This amends 58c2b0a848 libs/fst directly includes relevant
ardour C++ code, so lib/fst must not link against libardour.
The problem was that 58c2b0a848 introduced additional
dependencies on other libardour functions.
libardourcp and now libardour_midisurface are not control
surfaces, but helper libraries for those.
They need to be deployed to the library folder (shared between
ctrl surfaces) and not scanned as ctrl surfaces at runtime.
Writing partial messages will lead to undefined behavior.
This does not generally happen (LV2 forge prevents overflow
of the Atom buffer itself), however if the GUI is frozen messages
may accumulate in Ardour's Ringbuffer.
Processor::deactivate must not be called concurrently with
processing. e.g. Threading rules https://lv2plug.in/ns/lv2core
This fixes a potential crash when freezing tracks
