History
Cakewalk's Dimension sampler is the new sampler in the Project 5 version 2 package. It's roots can be traced back to Cakewalk SFZ and SFZ+ samplers, as the author of those authored Dimension.

The SFZ sampler is a free SoundFont player, and SFZ+ can play SoundFont's and other formats.

Disk and File Format
Dimension uses regular DOS format and use a text-based file format, which is really handy if you want to bulk edit something.
