When fluidsynth is run as a service using systemd, make sure
the service is considered started only when it is ready to process events.
In order to do so:
- Add an optional runtime dependency to libsystemd to the fluidsynth executable
- Change the systemd service type to "notify"
- Have fluidsynth notify systemd that the service is started after the server is started
- Have fluidsynth notify systemd that the service is stopping after joining the server thread
possibly due to glibc-2.29 commit 424c4f60ed6190e2ea0e72e0873bf3ebcbbf5448
pow is using fused-multiply-add (fma) if available.
That caused the fluidsynth binaries to differ depending on
the build machine's CPU.
This was visible among others in
grep '7.58577575029183[56]e-04' fluidsynth-2.0.3/build/fluid_conv_tables.c
See https://reproducible-builds.org/ for why this is matters.
Closes#512.
Normalized value of MIDI sources (before unipolar or bipolar mapping) is always in the range [0..+1], regardless of MIDI event (even for FLUID_MOD_PITCHWHEEL).
- When primary source input (src1) is set to General Controller
'No Controller', output will be forced to 0.0 at synthesis time
(see fluid_mod_get_value()).
That means that the minimum value of the modulator will be always 0.0.
We need to force amount value to 0 to ensure a correct evaluation of the
minimum value later (see fluid_voice_get_lower_boundary_for_attenuation()).
- When secondary source input (src2) is set to General
Controller 'No Controller', output will be forced to +1.0 at synthesis time
(see fluid_mod_get_value()).
That means that this source will behave unipolar only. We need to force the
unipolar flags to ensure the modulator will behave correctly later in
fluid_voice_get_lower_boundary_for_attenuation().
This change removes the warning message if retrieving the soundfont file
modification time fails in the sample cache loader. The warning made sense
while we didn't have mtime support on all platforms, but after switching
to GLibs g_stat, it's no longer needed.
To reduce the number of calls to fluid_get_file_modification_time and also
get rid of a possible race condition, getting the mtime has been moved to
fluid_samplecache_load.
This change also fixes#483 because it removes the bogus warning messages
if a soundfont was loaded from memory by abusing the filename to store a
pointer.
- v variable is renamed min_val for clarity.
- This fix a bug when calculating the possible minimun
value (min_val) of a modulator. min_val should only
be dependant of:
- signs of mapped sources (ie bipolar [-1..+1] or unipolar [0..+1])
- sign of amount.
- absolute value of amount.
