Yes, FLAC is not optimal in many ways...

James, does my thought that "a simple piano or sax waveform, would compress better than a complex song" have any logic? If yes, maybe that is the way they do it.

Of course all of the thread is based on the condition "we at Ketron managed to compress losslesly on a 12:1 ratio", being true.

(true as in Boolean logic, I am not implyying they lie to us)
