Hi Sissle,

how many files are saved depends on which parts of the instrument are used in a song. If you only play melodietracks in the sequencer it would be enough to store only the SEQ-file. If the song is also using patterns which are in the composer you have to store SEQ and CMP. If you also use edited sounds out of the SOUND MEMORY area you also have to store TM and so on. Of course if you store everytime all parts you will be save that the song will sound correctly anyway but in this case the loading time will be longer as necessary. Hope this explanations will help you for a better understanding.
