Can somone tell me the main advantages of saving a sequence file as sd sound vs technics? I'm not hearing too much difference in sound quality between the two when played back and load time appears to be the same as well..From my little experience with it is as follows: if you save the song as a technics file on the sd card, you can alter volumes on each track when playing it back live. the disadvantage is only 3 user groups? If saved to SD sound, you cannot alter individual track volumes but you can have access to larger play lists. I'm sure there are other pro's and con's as I eventually want to add real audio tracks to my sequences so I'm unsure what format would be best? One think I noticed is that when you save a sequence as SD audio, the changes in sound (such a key shift) that were altered under part setting do not carry over. any input on this topic would be appreciated!
