I am describing the Freeze, but I figure that having different tones ready to be sustained would give me a broader pallette. For instance there are some songs we do in church where having a quiet "pad" would be great and that can be programmed with perhaps less initial "thud" from the bass. The element of progammability is what does it for me.
Obv, when I talk of programmability I am talking about the geeks at work doing that for me.
