They are small in size and can be converted to STS, Giga, Kontakt and many apps w/ decent conversion utilities.
My interest in STS has grown lately because I am hoping that SC's 64bit drivers might address the STS limitation w/ 32bit O.S.'s.
I will still use Kontakt 3.0 and Gigastudio in 64bit thanks to Kontakt 3,5 now being 64bit and converting Gigastudio libraries.
It would be sweet to have limitless RAM is STS for loops and one shot SFX with that great 32bit Integer sound that I love from VDAT.
I might even get some Bass Pedals like my Brotha' from down under Wayne.
