C++ (Cpp) SetVoiceVolume Examples

Example #1

File: i_oplmusic.c Project: tm512/Mint-Doom

static void I_OPL_SetMusicVolume(int volume)
{
    unsigned int i;

    // Internal state variable.

    current_music_volume = volume;

    // Update the volume of all voices.

    for (i=0; i<OPL_NUM_VOICES; ++i)
    {
        if (voices[i].channel != NULL)
        {
            SetVoiceVolume(&voices[i], voices[i].note_volume);
        }
    }
}

Example #2

File: Ims.cpp Project: sopepos/imsplayer_osx

    if (m_ims == NULL) return false;

//	YM3812ResetChip(ym3812p);
