plSynthInit :: Ptr CFloat -> IO ()

Initialize the lookup table for all instruments. This needs to be done only once.

The table will be written to the memory pointed to by tab_buffer, which must be PL_SYNTH_TAB_LEN elements long or PL_SYNTH_TAB_SIZE bytes in size.

plSynthTabSize :: Int

Amount of memory needed for plSynthInit.

plSynthSoundLen :: Ptr PlSynthSoundT -> IO Int

Determine the number of samples needed for one channel of a particular sound effect.

plSynthSound :: Ptr PlSynthSoundT -> Ptr Int16 -> IO Int

Generate a stereo sound into the buffer pointed to by samples.

The buffer must be at least pl_synth_sound_len() * 2 elements long.

plSynthSongLen :: Ptr PlSynthSongT -> IO Int

Determine the number of samples needed for one channel of a particular song.

plSynthSong :: Ptr PlSynthSongT -> Ptr Int16 -> Ptr Int16 -> IO Int

Generate a stereo song into the buffer pointed to by samples, with temporary storage provided to by temp_samples.

The buffers samples and temp_samples must each be at least pl_synth_song_len() * 2 elements long.
