WildMidi_SetOption - Set a library option for a specific midi




#include <wildmidi_lib.h>

int WildMidi_SetOption (midi *handle, uint16_t options, uint16_t setting)


Set a library option for a specific midi.

The identifier obtained from opening a midi file with WildMidi_Open(3) or WildMidi_OpenBuffer(3)

options The option or options you wish to change.

By default the library uses linear volume levels typically used in computer MIDI players. These can differ somewhat to volume levels found on some midi hardware which may use a volume curve based on decibels. This option sets the volume levels to what you'd expect on such devices.
By default libWildMidi uses linear interpolation for the resampling of the sound samples. Setting this option enables the library to use a resampling method that attempts to fill in the gaps giving richer sound.
libWildMidi has an 8 reflection reverb engine. Use this option to give more depth to the output.
Makes libWildMidi to automatically rewind when it reaches the end, so the file would play in continuous loop.
Strips silence at song start.
This option tells WildMidi_GetMidiOutput(3) to output type-0 format data for type-2 files.
Some files have the lyrics in the text meta event. This option reads lyrics from there instead.
To turn on an option, repeat that option here. To turn off an option, do not put the option here.
WildMidi_SetOption(handle, WM_MO_REVERB, WM_MO_REVERB);
WildMidi_SetOption(handle, WM_MO_REVERB, 0);


Returns -1 on error, otherwise returns 0.
