Yes I am a beta tester as well, but that does not change the fact that Gigastudio is a huge upgrade in features from Gigasampler. Anyone that is looking to get more out of Gigasampler will not be disappointed with Gigastudio. Tom has already mentioned many of the great new features, so I won\'t add my list except for the 64 midi channels, but this program is simply awesome. Once you get the hang of the new mixer interface, I doubt you will miss the old Gigasampler. Simply put, the Gigastudio is better than the Gigasampler in every way.
