This document explains what sostenuto pedal is compared to sustain pedal. It is intended for a musician playing live. It gives information about specifications and implementation in fluidsynth.
Fixes a use-after-free when the MIDI player is deleted before the audio
driver, because the synthesis thread is still actively making callbacks
on the sample timer, which is deleted by the player though.
Enabling the option supresses the default welcome message and
some other text output that normally gets printed to stdout.
It also slightly changes the way the welcome message and argument
errors are handled: in case of an argument error, the welcome message
is never printed.
Previously, sample timers were deleted in fluid_player_stop() which caused a use-after-free when at the same time the sample timers were advanced by the synthesizer thread. This was incorrectly addressed in 5d3f727547 . Deleting sample timers is now done in delete_fluid_player(). A broken application could still crash if it does not respect the order of object creation though. At least now, this issue is properly documented.
In an out of memory situation, fluid_synth_t::voice and fluid_synth_t::channel may not be fully initialized, causing a NULL dereference and heap corruption in delete_fluid_synth().
By default, libinstpatch silently adds all SF2 default modulators to the
converted DLS voices. Since fluidsynth respects the modulators provided
by libinstpatch, those modulators would conflict with the default
modulator list managed by fluidsynth. This is only noticeable, if the
user used fluidsynth's API to manipulate default modulators.
When compiled with compatibility for WinXP (toolset v141_xp), read() may return 0 (EOF) rather than '\n' which led to an early exit of the shell after a single user input.
