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.
If we move UNKN_ID to the bottom of the enum, in the for() cycle inside chunkid() if the value is not found then the "i" variable will be already UNKN_ID.
