Hi, I'm planning to get a secondhand SP4-7 next week and I'm intrigued by the possibility of adding some of the sounds from the PC3Le as well as the other free soundbanks on the Kurzweil site. My question is this: are there sounds that are on this massive list from the PC3LE that crossover with the SP4-7 factory sounds and the Kurzweil site downloads or are they all unique?

For instance, I see a sound called Turntbltron on one of the free download zips on the Kurzweil site and a sound called Moby Turntbltron on the list of PC3LE list and was wondering if they are the same?

The reason I ask is I need as many mellotron sounds as I can get on this thing so the more possibilities the better!
