Example #1

void CVRC6Sawtooth::RefreshChannel()
{
	unsigned int Period = CalculatePeriod();

	unsigned char HiFreq = (Period & 0xFF);
	unsigned char LoFreq = (Period >> 8);

	unsigned int TremVol = GetTremolo();
	int Volume = (m_iSeqVolume * (m_iVolume >> VOL_COLUMN_SHIFT)) / 15 - TremVol;

	Volume = (Volume << 1) | ((m_iDutyPeriod & 1) << 5);
