It can happen that the main AlsaAudioBackend::_device_reservation
is still busy while I/O devices are set. In this case a
dedicated AlsaDeviceReservation needs to be used which can fail
silently.
A common example is disconnecting a USB device while it is in
use. The Halted signal can show the session dialog, which calls
set_input_device_name before the device reservation of the
unplugged device terminated.
ALSA backend modified the internal state when different devices
were used, re-assigning one (usually input-device) to "None"
when it's resampled. This lead to EngineHints not matching the
EngineState, and autostart was disabled, and a dialog
"Engine I/O device has changed since you last opened this session."
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.
Playlist::add_region copies regions as needed (see 8d045e15dc),
without forking the Source.
This fixes an issue when importing MIDI files. When
midi-copy-is-fork is enabled (enabled by default), the
RegionFactory::create call used during import forked the
region. This resulted in two Sources being created for each
imported MIDI file.
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).
Make MainClock more self-contained and generic by moving logic from the
Config system and to the class itself, while making the class less aware
of how it is used in the config system.
It is slightly dirty to store the initial AudioClock widget name in
MainClock, but less dirty than having to pass the whole name correctly
every time the delta mode changes.
Also avoid confusing use of 'mode', which in AudioClock is used for the
units/formatting of the clock.
We would like to introduce an actual setter, but the most appropriate
name for it was used by something else: the high level callback invoked
when selecting the menu item.
* use UTF-8 music symbols for both
- note length
- dynamics (velocity)
This allows for both color theming as well as scaling. Previously
fixed size, black icons were used.
* directly rely on ActionManager actions for radio actions
This simplifies code and removes ambiguities.
* hide Bank/Patch buttons. Those actions are not implemented
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.
