These two files are not ordinary C files, and are being compiled
through #include's in other C source files, not through invoking
compiler on generated files. This might confuse both developers and
automated systems.
For longer explanation see discussion in #800.
Resets the default sample timer properly, allowing the internal
MIDI file player to restart its playlist on any other time but
the initial first.
Lets Qsynth play any MIDI files that are drag-n-dropped, anytime
after the first, following synth engine initialization.
In `fluid_rvoice_mixer.c`:`fluid_rvoice_mixer_process_fx()`:
If an audio processing callback is used, `mix_fx_to_out` would be `FALSE`. As a result, `in_ch` and `out_ch_l` points to the same buffer.
In `fluid_chorus.c`:`fluid_chorus_processreplace()`:
```C
/* process stereo unit */
/* store the chorus stereo unit d_out to left and right output */
left_out[sample_index] = d_out[0] * chorus->wet1 + d_out[1] * chorus->wet2;
right_out[sample_index] = d_out[1] * chorus->wet1 + d_out[0] * chorus->wet2;
/* Write the current input sample into the circular buffer */
push_in_delay_line(chorus, in[sample_index]);
```
Here the chorus processing code writes to the left output buffer (which will overwrite the input buffer in this case) before the sample from the input buffer is stored into the delay buffer, making the chorus output all zeros. If no audio processing callback is used, `mix_fx_to_out` would be `TRUE` and `in` and `left_out` will not point to the same buffer, therefore the order doesn't matter.
Simply swapping the two steps should be a sufficient fix. This patch also apply the same change to `fluid_chorus_processmix` only for the sake of consistency (since they are almost exact copies of each other).
Resolves#751.
If polyphony is exceeded and FluidSynth has to allocate a voice by
calling fluid_synth_free_voice_by_kill_LOCAL(), two problems occur:
1)The value returned by fluid_synth_get_active_voice_count() never
returns back to 0.
2)SoundFont samples are not unref'd properly, and therefore if an attempt is
made to unload the SoundFont, the deferred unload timer is started, and
fluid_synth_sfunload_callback() unsuccessfully tries to unload the SoundFont forever.
These 2 issues are fixed by this commit.
It could be that during runtime an older version of libinstpatch is used than the one fluidsynth was compiled against. In this case, libinstpatch will fail to load DLS fonts, because libinstpatch's initialization semantics don't match those compiled into fluidsynth.
This PR allows the reverb to pre-allocate the memory needed for the maximum sample-rate of the synth. That means that on sample rate change there are no memory allocation and the function fluid_revmodel_samplerate_change() should always return FLUID_OK.
The PR addresses discussion in #608.
Stopping `dsound `before stopping `audio thread` avoid dsound playing transient glitches between the time audio task is stopped and dsound will be released. These short trailing glitches are particularly audible when captured by a reverb connected on output.
For some reason, the configure command must be specified explicitly in the `gentables` build step. Otherwise, the ARM target compiler will be used to build `make_tables` rather than the host compiler.
Now that microsoft/vcpkg#10485 has been completed, an ARM CI build can be added to AppVeyor. Also, the build status table in the README has been updated.
