Well because of this and a couple other issues I tend to use 32 bit most often myself. Sometimes I've played around with the jaws curser and got things to work too. I notice that some of the larger samples load up quite abit faster with the 64 bit version. Is there any other reason we're suppose to figure 64 bit is better? I know I can't use my rex or sfz files with the 64 bit sonar.
