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.
I tried to check the generated ASM code when WITH_FLOAT macro is defined and when it is undefined. In both cases I noticed that there are some points where the math number are converted from float to double and viceversa. Actually this happens whether the FPU is present or not, perhaps for granting the right precision in digits. I also noticed few points that could be simplified a bit by using integer math, so I also included them.
* Since fluid_voice_get_actual_key() returns an integer value, the value 60 could be subtracted directly as integer, the code generated looks a bit better.
* FLUID_NOISE_FLOOR needs to be cast to fluid_real_t to generate a bit more efficient code.
* DC_OFFSET needs a cast to fluid_real_t to generate a bit more efficient code.
* "last_fres" and "output_rate" are already fluid_real_t, so they do not need type cast.
* "chan_add", "par1_add" and "par2_add" are integer types, so they can be added without FPU. "chan_mul", "par1_mul" and "par2_mul" are already fluid_real_t, so they do not need type cast. Instead, the constant 0.5 needs cast to fluid_real_t to be more efficient.
Libreadline is already used into fluid_istream_readline().
In my opinion, there is no need to have this duplicated code, so I would suggest to move the call to add_history() into fluid_sys.h
Closes#460.
Since 'data' is an integer value clipped between +/-8192 and 'nrpn_scale' is a char value, this calculation could be done with integers and then return the fluid_real_t value.
Addresses #455.
