This "high resolution" mode comes from the 6 bit amplitude control on each channel. Since most DAC sound generators don't have this, then the only resolution available is the bits going into the DAC itself. And the only way to change the volume is to change the waveform, hence losing resolution. With the extra 6 bit amplitude, you can use the fully detailed waveform so that quieter notes still have the full 8 bit resolution of the original waveform. Net effect, it sounds better. (Another way this could be used is to have the CPU create sound and volume data "on the fly" at full speed and feed it into both sound & volume regs, hence gaining a "true" 14 bit resolution.) –>Steve Bennett
