Synopsis

#include <wildmidi_lib.h>

Description

Initializes libWildMidi in preparation for playback. This function only needs to be called once by the program using libWildMidi.

config-file
The file that contains the instrument configuration for the library.
rate
The sound rate you want the the audio data output at. Rates accepted by libWildMidi are 11025 - 65000.
options

The initial options to set for the library. see below.

WM_MO_LOG_VOLUME
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.
WM_MO_ENHANCED_RESAMPLING
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.
WM_MO_REVERB
libWildMidi has an 8 reflection reverb engine. Use this option to give more depth to the output.
WM_MO_WHOLETEMPO
Ignores the fractional or decimal part of a tempo setting. If you are having timing issues try WM_MO_ROUNDTEMPO before trying this option. This option added due to some software not supporting fractional tempos allowable in the MIDI specification.
WM_MO_ROUNDTEMPO
Rounds the fractional or decimal part of a tempo setting. Try this option is you are having timing issues, if this fails then try WM_MO_WHOLETEMPO. This option added due to some software not supporting fractional tempos allowable in the MIDI specification.
