Although, contrary to popular belief, you can actually do something about this in software - to make samples play loud on all C64s, generate some additional DC offset by setting each oscillator to 0 pulse width and turning them on with pulse waveform, maximum sustain. It might also be possible to get some extra offset with certain filter settings. Richard - This message was sent through the cbm-hackers mailing list.
